CSS body gradient

CSS body gradient - css

I am making a background in the body element but when I make a background it uses the window height (only the visible height) and if the user scrolls the page down the background repeats it self. If I use no-repeat the rest of the page is in solid color.
I have used background-size: 100% 100%; but still not working.
I only want a background that goes from #ccc to #000 and fills the entire page without repeating itself.....
Can anyone be so kind and help me? Thanks in advanced!
EDIT:
My code is:
body {
padding: 0;
margin: 0;
width: 100%;
height: 100%;
background-repeat: no-repeat;
background: rgb(204,204,204);
background: -moz-linear-gradient(top, rgba(204,204,204,1) 0%, rgba(0,0,0,1) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(204,204,204,1)), color-stop(100%,rgba(0,0,0,1)));
background: -webkit-linear-gradient(top, rgba(204,204,204,1) 0%,rgba(0,0,0,1) 100%);
background: -o-linear-gradient(top, rgba(204,204,204,1) 0%,rgba(0,0,0,1) 100%);
background: -ms-linear-gradient(top, rgba(204,204,204,1) 0%,rgba(0,0,0,1) 100%);
background: linear-gradient(top, rgba(204,204,204,1) 0%,rgba(0,0,0,1) 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#cccccc', endColorstr='#000000',GradientType=0 );
}
LAST EDIT:
body {
background: #000;
background-repeat: no-repeat;
background-image: -webkit-gradient(linear, left top, left bottom, from(#ccc), to(#000)); /* for webkit browsers */
}
note: The best solution I found. When I scroll the window you can see the background color because the background-image does not repeat and as the background-image ends with the same background color everything is ok!

Unfortunately, you cannot stretch out background images, so what you are seeing is actually what you're supposed to see. Normally when sites use gradients as background images, they make it so the top of the gradient is flush with the top of the screen by setting background-position: 0 0, the gradient repeats itself horizontally by setting background-repeat: no-repeat, and then they set the background-color of the site to be the same color as the bottom of the gradient.
There are ways using CSS3 and filters in which you can create gradients for users, but there is a limited amount of browser-compatibility for these features. Here is a fiddle containing a gradient: http://jsfiddle.net/Wexcode/qhMx9/. See this article for more information about those features.

Display Sunset Effect with Gradients Above Background Image in Body

I'm trying to create a gradient based sunset effect on my website's background.
Example Link (with sunset effect, in the background) https://web.archive.org/web/20161017071941/https://www.embroideryaffair.com/about/
Try to scroll down on the example link & you will notice the "sunset" effect.
This is what I've achieved so far: https://sirsakisan101.provenreviews.com/
I was able to display the two palm images, side-by-side, by using the following code.
body {
background-image: url(https://sirsakisan101.provenreviews.com/wp-content/uploads/2019/01/left.png), url(https://sirsakisan101.provenreviews.com/wp-content/uploads/2019/01/right.png), url(https://sirsakisan101.provenreviews.com/wp-content/uploads/2019/01/sunsetbgbottom.png);
background-repeat: no-repeat, no-repeat, repeat-x;
background-attachment: fixed, fixed;
background-position: left top, right top, bottom;
}
Now, I'm trying to use the following code (mentioned below) for achieving the sunset effect on my background images, but it is not working. I've also tried removing the "before" element & adding the background images, along with gradients but then, it is appearing above the background images.
body:before {
background: linear-gradient(bottom, rgb(255,203,112) 0%, rgb(107,138,169) 30%, rgb(1,44,87) 100%);
background: -o-linear-gradient(bottom, rgb(255,203,112) 0%, rgb(107,138,169) 30%, rgb(1,44,87) 100%);
background: -moz-linear-gradient(bottom, rgb(255,203,112) 0%, rgb(107,138,169) 30%, rgb(1,44,87) 100%);
background: -webkit-linear-gradient(bottom, rgb(255,203,112) 0%, rgb(107,138,169) 30%, rgb(1,44,87) 100%);
background: -ms-linear-gradient(bottom, rgb(255,203,112) 0%, rgb(107,138,169) 30%, rgb(1,44,87) 100%);
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#012c57', endColorstr='#ffcb70');
background: -webkit-gradient( linear, left bottom, left top, color-stop(0, rgb(255,203,112)), color-stop(0.3, rgb(107,138,169)), color-stop(1, rgb(205,217,230)) ) !important;
}
I want to display this code behind my background images, to achieve the sunset effect from the example website. I can't understand why it is not working. I will be grateful for any help.
Thank You.

You can do it with another html element inside the background image one.
<div> // has your background image
<div class="gradient"> // will have the gradiant style
</div>
</div>
css
.gradient {
background: linear-gradient( rgba(255,255,255,0.23) 0%, rgba(164,49,34, .85) 100%);
}
Here is an example fiddle
Note i just simplified the gradient css. Keep your own styling.
Consider the way you use the body tag like you currently do. You need to make sure the div inside (with the gradient) spans directly on top of the other div. Maybe you have to do something like
.parent {
// The element with the image
position: relative;
}
.child {
// the element with the gradient
position absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
}

You can directly add the gradient to the other background-images (since the gradient property is considered a background image) like this:
body {
background-image: url(https://sirsakisan101.provenreviews.com/wp-content/uploads/2019/01/left.png),
url(https://sirsakisan101.provenreviews.com/wp-content/uploads/2019/01/right.png),
url(https://sirsakisan101.provenreviews.com/wp-content/uploads/2019/01/sunsetbgbottom.png),
-webkit-linear-gradient(bottom, rgb(255,203,112) 0%, rgb(107,138,169) 30%, rgb(1,44,87) 100%);
}
That worked for me and it's much easier than adding additional elements ;)

how to implement css3 gradient property with image [duplicate]

How do I use CSS3 gradients for my background-color and then apply a background-image to apply some sort of light transparent texture?

Multiple backgrounds!
body {
background: #eb01a5;
background-image: url("IMAGE_URL"); /* fallback */
background-image: url("IMAGE_URL"), linear-gradient(#eb01a5, #d13531); /* W3C */
}
These 2 lines are the fallback for any browser that doesn't do gradients.
See notes for stacking images only IE < 9 below.
Line 1 sets a flat background color.
Line 2 sets the background image fallback.
The final line sets a background image and gradient for browsers that can handle them.
Line 3 is for all relatively modern browsers.
Nearly all current browsers have support for multiple background images and css backgrounds. See http://caniuse.com/#feat=css-gradients for browser support. For a good post on why you don't need multiple browser prefixes, see http://codepen.io/thebabydino/full/pjxVWp/
Layer Stack
It should be noted that the first defined image will be topmost in the stack. In this case, the image is on TOP of the gradient.
For more information about background layering see http://www.w3.org/TR/css3-background/#layering.
Stacking images ONLY (no gradients in the declaration) For IE < 9
IE9 and up can stack images this same way. You could use this to create a gradient image for ie9, though personally, I wouldn't. However to be noted when using only images, ie < 9 will ignore the fallback statement and not show any image. This does not happen when a gradient is included. To use a single fallback image in this case I suggest using Paul Irish's wonderful Conditional HTML element along with your fallback code:
.lte9 #target{ background-image: url("IMAGE_URL"); }
Background position, sizing etc.
Other properties that would apply to a single image may also be comma separated. If only 1 value is supplied, that will be applied to all stacked images including the gradient. background-size: 40px; will constrain both the image and the gradient to 40px height and width. However using background-size: 40px, cover; will make the image 40px and the gradient will cover the element. To only apply a setting to one image, set the default for the other: background-position: 50%, 0 0; or for browsers that support it use initial: background-position: 50%, initial;
You may also use the background shorthand, however this removes the fallback color and image.
body{
background: url("IMAGE_URL") no-repeat left top, linear-gradient(#eb01a5, #d13531);
}
The same applies to background-position, background-repeat, etc.

If you also want to set background position for your image, than you can use this:
background-color: #444; // fallback
background: url('PATH-TO-IMG') center center no-repeat; // fallback
background: url('PATH-TO-IMG') center center no-repeat, -moz-linear-gradient(top, #startColor, #endColor); // FF 3.6+
background: url('PATH-TO-IMG') center center no-repeat, -webkit-gradient(linear, 0 0, 0 100%, from(#startColor), to(#endColor)); // Safari 4+, Chrome 2+
background: url('PATH-TO-IMG') center center no-repeat, -webkit-linear-gradient(top, #startColor, #endColor); // Safari 5.1+, Chrome 10+
background: url('PATH-TO-IMG') center center no-repeat, -o-linear-gradient(top, #startColor, #endColor); // Opera 11.10
background: url('PATH-TO-IMG') center center no-repeat, linear-gradient(to bottom, #startColor, #endColor); // Standard, IE10
or you can also create a LESS mixin (bootstrap style):
#gradient {
.vertical-with-image(#startColor: #555, #endColor: #333, #image) {
background-color: mix(#startColor, #endColor, 60%); // fallback
background-image: #image; // fallback
background: #image, -moz-linear-gradient(top, #startColor, #endColor); // FF 3.6+
background: #image, -webkit-gradient(linear, 0 0, 0 100%, from(#startColor), to(#endColor)); // Safari 4+, Chrome 2+
background: #image, -webkit-linear-gradient(top, #startColor, #endColor); // Safari 5.1+, Chrome 10+
background: #image, -o-linear-gradient(top, #startColor, #endColor); // Opera 11.10
background: #image, linear-gradient(to bottom, #startColor, #endColor); // Standard, IE10
}
}

One thing to realize is that the first defined background image is topmost in the stack. The last defined image will be bottommost. That means, to have a background gradient behind an image, you would need:
body {
background-image: url("http://www.skrenta.com/images/stackoverflow.jpg"), linear-gradient(red, yellow);
background-image: url("http://www.skrenta.com/images/stackoverflow.jpg"), -webkit-gradient(linear, left top, left bottom, from(red), to(yellow));
background-image: url("http://www.skrenta.com/images/stackoverflow.jpg"), -moz-linear-gradient(top, red, yellow);
}
You could also define background positions and background size for the images.
I put together a blog post about some interesting things you can do with CSS3 gradients

you could simply type :
background: linear-gradient(
to bottom,
rgba(0,0,0, 0),
rgba(0,0,0, 100)
),url(../images/image.jpg);

my solution:
background-image: url(IMAGE_URL); /* fallback */
background-image: linear-gradient(to bottom, rgba(0,0,0,0.7) 0%,rgba(0,0,0,0.7) 100%), url(IMAGE_URL);

I always use the following code to make it work. There are some notes:
If you place image URL before gradient, this image will be displayed above the gradient as expected.
.background-gradient {
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -moz-linear-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -webkit-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -webkit-linear-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -o-linear-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -ms-linear-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, linear-gradient(135deg, #6ec575 0, #3b8686 100%);
height: 500px;
width: 500px;
}
<div class="background-gradient"></div>
If you place gradient before image URL, this image will be displayed under the gradient.
.background-gradient {
background: -moz-linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: -webkit-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: -webkit-linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: -o-linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: -ms-linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
width: 500px;
height: 500px;
}
<div class="background-gradient"></div>
This technique is just the same as we have multiple background images as describe here

I had an implementation where I needed to take this technique a step farther, and wanted to outline my work. The below code does the same thing but uses SASS, Bourbon, and an image sprite.
#mixin sprite($position){
#include background(url('image.png') no-repeat ($position), linear-gradient(#color1, #color2));
}
a.button-1{
#include sprite(0 0);
}
a.button-2{
#include sprite (0 -20px);
}
a.button-2{
#include sprite (0 -40px);
}
SASS and Bourbon take care of the cross browser code, and now all I have to declare is the sprite position per button. It is easy to extend this principal for the buttons active and hover states.

If you have strange errors with downloading background images use W3C Link checker: https://validator.w3.org/checklink
Here are modern mixins that I use (credits: PSA: don't use gradient generators):
.buttonAkc
{
.gradientBackground(#imageName: 'accept.png');
background-repeat: no-repeat !important;
background-position: center right, top left !important;
}
.buttonAkc:hover
{
.gradientBackgroundHover('accept.png');
}
.gradientBackground(#startColor: #fdfdfd, #endColor: #d9d9db, #imageName)
{
background-color: mix(#startColor, #endColor, 60%); // fallback
background-image: url("#{img-folder}/#{imageName}?v=#{version}"); // fallback
background: url("#{img-folder}/#{imageName}?v=#{version}") no-repeat scroll right center, -webkit-linear-gradient(top, #startColor 0%, #endColor 100%) no-repeat scroll left top; // Chrome 10-25, Safari 5.1-6
background: url("#{img-folder}/#{imageName}?v=#{version}") no-repeat scroll right center, linear-gradient(to bottom, #startColor 0%, #endColor 100%) no-repeat scroll left top;
}
.gradientBackgroundHover(#imageName)
{
.gradientBackground(#fdfdfd, #b5b6b9, #imageName);
}

If you want a gradient with a single background image in the center, you can do it with one line of code like this:
body {
background: url(logo.png) no-repeat fixed center center, linear-gradient(#00467f, #a5cc82) fixed;
}

Use background-blend-mode and rgba to mix the background image and color
This is what you need:
.myblendedbg {
background-image: url("some_image.png");
background-color: rgba(0, 0, 0, 0.85); /* use rgba for fine adjustments */
background-blend-mode: multiply;
}
If you adjust the alpha value of the rgba color value (it's at .85 in the example), you can control the transparency.
Also, background-blend-mode has other values you can play with to get some really creative results.
NOTE: background-blend-mode: color; fails on Firefox, while multiply works on all modern browsers

Here is a MIXIN that I created to handle everything that people might like to use:
.background-gradient-and-image (#fallback, #imgUrl, #background-position-x, #background-position-y, #startColor, #endColor) {
background: #fallback;
background: url(#imgUrl) #background-position-x #background-position-y no-repeat; /* fallback */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -webkit-gradient(linear, left top, left bottom, from(#startColor) #background-position-x #background-position-y no-repeat, to(#endColor)); /* Saf4+, Chrome */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -webkit-linear-gradient(top, #startColor, #endColor); /* Chrome 10+, Saf5.1+ */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -moz-linear-gradient(top, #startColor, #endColor); /* FF3.6+ */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -ms-linear-gradient(top, #startColor, #endColor); /* IE10 */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -o-linear-gradient(top, #startColor, #endColor); /* Opera 11.10+ */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, linear-gradient(top, #startColor, #endColor); /* W3C */
}
This can be used like so:
.background-gradient-and-image (#f3f3f3, "../images/backgrounds/community-background.jpg", left, top, #fafcfd, #f2f2f2);
Hope you guys find this helpful.

I was trying to do the same thing. While background-color and background-image exist on separate layers within an object -- meaning they can co-exist -- CSS gradients seem to co-opt the background-image layer.
From what I can tell, border-image seems to have wider support than multiple backgrounds, so maybe that's an alternative approach.
http://articles.sitepoint.com/article/css3-border-images
UPDATE: A bit more research. Seems Petra Gregorova has something working here --> http://petragregorova.com/demos/css-gradient-and-bg-image-final.html

You could use multiple background: linear-gradient(); calls, but try this:
If you want the images to be completely fused together where it doesn't look like the elements load separately due to separate HTTP requests then use this technique. Here we're loading two things on the same element that load simultaneously...
Just make sure you convert your pre-rendered 32-bit transparent png image/texture to base64 string first and use it within the background-image css call (in place of INSERTIMAGEBLOBHERE in this example).
I used this technique to fuse a wafer looking texture and other image data that's serialized with a standard rgba transparency / linear gradient css rule. Works better than layering multiple art and wasting HTTP requests which is bad for mobile. Everything is loaded client side with no file operation required, but does increase document byte size.
div.imgDiv {
background: linear-gradient(to right bottom, white, rgba(255,255,255,0.95), rgba(255,255,255,0.95), rgba(255,255,255,0.9), rgba(255,255,255,0.9), rgba(255,255,255,0.85), rgba(255,255,255,0.8) );
background-image: url("data:image/png;base64,INSERTIMAGEBLOBHERE");
}

If you have to get gradients and background images working together in IE 9 (HTML 5 & HTML 4.01 Strict), add the following attribute declaration to your css class and it should do the trick:
filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0, startColorstr='#000000', endColorstr='#ff00ff'), progid:DXImageTransform.Microsoft.AlphaImageLoader(src='[IMAGE_URL]', sizingMethod='crop');
Notice that you use the filter attribute and that there are two instances of progid:[val] separated by a comma before you close the attribute value with a semicolon. Here's the fiddle. Also notice that when you look at the fiddle the gradient extends beyond the rounded corners. I don't have a fix for that other not using rounded corners. Also note that when using a relative path in the src [IMAGE_URL] attribute, the path is relative to the document page and not the css file (See source).
This article (http://coding.smashingmagazine.com/2010/04/28/css3-solutions-for-internet-explorer/) is what lead me to this solution. It's pretty helpful for IE-specific CSS3.

I resolve the problem in that way. I define Gradient in HTML and background image in the Body
html {
background-image: -webkit-gradient(linear, left bottom, right top, color-stop(0.31, rgb(227, 227, 227)), color-stop(0.66, rgb(199, 199, 199)), color-stop(0.83, rgb(184, 184, 184)));
background-image: -moz-linear-gradient(left bottom, rgb(227, 227, 227) 31%, rgb(199, 199, 199) 66%, rgb(184, 184, 184) 83%);
height: 100%
}
body {
background: url("http://www.skrenta.com/images/stackoverflow.jpg");
height: 100%
}

this is a background image with Gradient overlay, the 26% is the opacity and 7deg is the gradient position
CSS Gradient Generator
backgroundImage: `linear-gradient(7deg, rgba(2,0,36,1) 0%, rgba(39,17,68,1) 26%, rgba(10,19,20,0.49343487394957986) 100%), url('backgroundImg.jpeg')`,

I wanted to make span button with background image, background gradient combination.
http://enjoycss.com/ helped to do my work task. Only I have to remove some auto generated additional CSS. But it's really nice site build your scratch work.
#nav a.link-style span {
background: url("../images/order-now-mobile.png"), -webkit-linear-gradient(0deg, rgba(190,20,27,1) 0, rgba(224,97,102,1) 51%, rgba(226,0,0,1) 100%);
background: url("../images/order-now-mobile.png"), -moz-linear-gradient(90deg, rgba(190,20,27,1) 0, rgba(224,97,102,1) 51%, rgba(226,0,0,1) 100%);
background: url("../images/order-now-mobile.png"), linear-gradient(90deg, rgba(170,31,0,1) 0, rgba(214,18,26,1) 51%, rgba(170,31,0,1) 100%);
background-repeat: no-repeat;
background-position: 50% 50%;
border-radius: 8px;
border: 3px solid #b30a11;
}

For my responsive design, my drop-box down-arrow on the right side of the box (vertical accordion), accepted percentage as position. Initially the down-arrow was "position: absolute; right: 13px;". With the 97% positioning it worked like charm as follows:
> background: #ffffff;
> background-image: url(PATH-TO-arrow_down.png); /*fall back - IE */
> background-position: 97% center; /*fall back - IE */
> background-repeat: no-repeat; /*fall back - IE */
> background-image: url(PATH-TO-arrow_down.png) no-repeat 97% center;
> background: url(PATH-TO-arrow_down.png) no-repeat 97% center, -moz-linear-gradient(top, #ffffff 1%, #eaeaea 100%);
> background: url(PATH-TO-arrow_down.png) no-repeat 97% center, -webkit-gradient(linear, left top, left bottom, color-stop(1%,#ffffff), color-stop(100%,#eaeaea));
> background: url(PATH-TO-arrow_down.png) no-repeat 97% center, -webkit-linear-gradient(top, #ffffff 1%,#eaeaea 100%);
> background: url(PATH-TO-arrow_down.png) no-repeat 97% center, -o-linear-gradient(top, #ffffff 1%,#eaeaea 100%);<br />
> filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#eaeaea',GradientType=0 );
P.S. Sorry, don't know how to handle the filters.

I hope this is cross-browser enough:
(modified base from gradient editor with black to transparent vertical gradient on top of image)
background-image: url('YOURIMAGE.JPG');
background-image: -moz-linear-gradient(left, rgba(0,0,0,1) 0%, rgba(0,0,0,0) 100%),url('YOURIMAGE.JPG'); /* FF3.6-15 */
background-image: -webkit-linear-gradient(left, rgba(0,0,0,1) 0%,rgba(0,0,0,0) 100%),url('YOURIMAGE.JPG'); /* Chrome10-25,Safari5.1-6 */
background-image: linear-gradient(to right, rgba(0,0,0,1) 0%,rgba(0,0,0,0) 100%),url('YOURIMAGE.JPG'); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#000000', endColorstr='#00000000',GradientType=1 ), progid:DXImageTransform.Microsoft.AlphaImageLoader(src='YOURIMAGE.JPG', sizingMethod='crop'); /* IE6-9 */

As a sure method way, you can just make a background image that is say 500x5 pixels, in your css use:
background-img:url(bg.jpg) fixed repeat-x;
background:#<xxxxxx>;
Where xxxxxx corresponds with the color that matches the final gradient color.
You could also fix this to the bottom of the screen and have it match the initial gradient color.

Vertically stacking a css gradient on top of a background image (not overlaid)

I've got a background image where the top row of pixels is a solid colour (it's a photo of a landscape). The idea would be to have this at the bottom of the page and then a CSS gradient above it that will stretch from the top of the page, stopping at the height of the image. There are lots of tutorials showing how to overlay/underlay the gradient, but they all assume that you want a full page gradient or the gradient overlaid on top of the background image.
What I have now is:
background: rgba(30, 53, 192, 1);
background: url("myimage.jpg") no-repeat center bottom, -moz-linear-gradient(top, #000 0%, #1E35C0 100%);
background: url("myimage.jpg") no-repeat center bottom, -webkit-gradient(linear, 0% 0%,0% 100%, from(#000), to(#1E35C0));
background: url("myimage.jpg") no-repeat center bottom, -webkit-linear-gradient(top, #000 0%,#1E35C0 100%);
background: url("myimage.jpg") no-repeat center bottom, -o-linear-gradient(top, #000 0%,#1E35C0 100%);
background: url("myimage.jpg") no-repeat center bottom, -ms-linear-gradient(top, #000 0%,#1E35C0 100%);
background: url("myimage.jpg") no-repeat center bottom, linear-gradient(top, #000 0%, #1E35C0 100%);
background-size: contain;
This has almost the desired effect. The CSS gradient is fine and the image is in the right place, but I don't know how to make the gradient stop above the image in a way that's nice and responsive. I can play with the percentages, but again, that only works if I know how tall the image is.
I know this is probably fairly easy in javascript, but I was hoping there's a clean CSS way to do it.

Assuming that your image has an aspect ratio of 4:1 (i.e. height is 25% of width), you can do this:
html, body {
margin: 0;
height: 100%;
}
body {
background-color: #ccc;
background-image: url("http://ima.gs/transparent/000/000/200%C3%9750-200x50.png")
, linear-gradient(to top, transparent 25vw, #fff 25vw, #00f 100%);
background-repeat: no-repeat;
background-position: center bottom;
background-size: contain;
}
The vw unit there in the gradient means percent of viewport width. So if the background image will stretch the full width of the viewport, and its height is 25% of its width, then its height will be equal to 25vw and you can start the gradient at 25vw from the bottom, and end at the page top.

Trouble getting a CSS vertical linear background gradient to display properly in all major browsers

I got it to display exactly how I want it in Firefox, but with every other browser there seems to be some problems. This website isn't exactly public (as in, no one knows of it) yet as I'm still trying to get things to display properly, but the URL is: http://www.mixbin.net (just view:source for the code - there's nothing server side interfering)
Firefox: Perfect.
Chrome: Perfect except the bottom margin is being ignored in the .content class.
Opera: Perfect except the bottom margin is being ignored in the .content class.
Safari: Displays gradient properly but forces a refresh as soon as you scroll halfway down the page.
Internet Explorer: Displays gradient properly but .content div is cut off where the gradient stops.
background:linear-gradient(top, #000000 0%, #353535 100%); /*W3C*/
background:-moz-linear-gradient(top, #000000 0%, #353535 100%); /*FF3.6+*/
background:-ms-linear-gradient(top, #000000 0%, #353535 100%); /*IE10+*/
background:-o-linear-gradient(top, #000000 0%, #353535 100%); /*Opera 11.10+*/
background:-webkit-gradient(linear, left top, left bottom, color-stop(0%, #000000), color-stop(100%, #353535)); /*Chrome,Safari4+*/
background:-webkit-linear-gradient(top, #000000 0%, #353535 100%); /*Chrome10+,Safari5.1+*/
filter:progid:DXImageTransform.Microsoft.gradient( startColorstr='#000000', endColorstr='#353535',GradientType=0 ); /*IE6-9*/
No images wanted. So please don't reply with, "just make a background image".
Update 2: Everything (including IE), is now working. I switched these two lines from:
background:-webkit-linear-gradient(top,#000000 0,#353535 100%);
background:-webkit-gradient(linear,left top,left bottom,color-stop(0,#000),color-stop(100%,#353535));
To:
background:-webkit-linear-gradient(top, #000000, #353535);
background:-webkit-gradient(linear, left top, left bottom, from(#000000), to(#353535));

If your CSS for the gradient is:
background: linear-gradient(top, #000000 0%, #353535 512px);
there will be no need for a <div> with height 512px. Unfortunately, this solution works for every browser except IE.
Back to your extra background <div> approach. I copied and modified your code a little. This works for all browsers.
body {
background: #353535;
}
.content {
background-color: white;
height: 1000px;
margin: 20px auto;
width: 300px;
z-index: 2;
position: relative;
}
#background {
position: absolute;
top: 0;
height: 512px;
width: 100%;
background: linear-gradient(top, #000000 0%, #353535 100%); /*W3C*/
background: -moz-linear-gradient(top, #000000 0%, #353535 100%); /*FF3.6+*/
background: -ms-linear-gradient(top, #000000 0%, #353535 100%); /*IE10+*/
background: -o-linear-gradient(top, #000000 0%, #353535 100%); /*Opera 11.10+*/
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #000000), color-stop(100%, #353535)); /*Chrome,Safari4+*/
background: -webkit-linear-gradient(top, #000000 0%, #353535 100%); /*Chrome10+,Safari5.1+*/
filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#000000', endColorstr='#353535', GradientType=0); /*IE6-9*/
}
<body>
<div id="background"></div>
<div class="content"></div>
</body>

This might not be the solution you are looking for but, since you will have to use hacks to make it looks the same on different browsers, why wont you use an image of the gradient and repeat it in the background.
If your background gradient is 300px, make the image with 300px height and 1px width (image size wont be over 1KB), and repeat it in your background
background: url('bg_gradient.jpg') repeat-x 0px 0px;
It will work on all the browsers without any hassle;

How do I combine a background-image and CSS3 gradient on the same element?

How do I use CSS3 gradients for my background-color and then apply a background-image to apply some sort of light transparent texture?

If you also want to set background position for your image, than you can use this:
background-color: #444; // fallback
background: url('PATH-TO-IMG') center center no-repeat; // fallback
background: url('PATH-TO-IMG') center center no-repeat, -moz-linear-gradient(top, #startColor, #endColor); // FF 3.6+
background: url('PATH-TO-IMG') center center no-repeat, -webkit-gradient(linear, 0 0, 0 100%, from(#startColor), to(#endColor)); // Safari 4+, Chrome 2+
background: url('PATH-TO-IMG') center center no-repeat, -webkit-linear-gradient(top, #startColor, #endColor); // Safari 5.1+, Chrome 10+
background: url('PATH-TO-IMG') center center no-repeat, -o-linear-gradient(top, #startColor, #endColor); // Opera 11.10
background: url('PATH-TO-IMG') center center no-repeat, linear-gradient(to bottom, #startColor, #endColor); // Standard, IE10
or you can also create a LESS mixin (bootstrap style):
#gradient {
.vertical-with-image(#startColor: #555, #endColor: #333, #image) {
background-color: mix(#startColor, #endColor, 60%); // fallback
background-image: #image; // fallback
background: #image, -moz-linear-gradient(top, #startColor, #endColor); // FF 3.6+
background: #image, -webkit-gradient(linear, 0 0, 0 100%, from(#startColor), to(#endColor)); // Safari 4+, Chrome 2+
background: #image, -webkit-linear-gradient(top, #startColor, #endColor); // Safari 5.1+, Chrome 10+
background: #image, -o-linear-gradient(top, #startColor, #endColor); // Opera 11.10
background: #image, linear-gradient(to bottom, #startColor, #endColor); // Standard, IE10
}
}

One thing to realize is that the first defined background image is topmost in the stack. The last defined image will be bottommost. That means, to have a background gradient behind an image, you would need:
body {
background-image: url("http://www.skrenta.com/images/stackoverflow.jpg"), linear-gradient(red, yellow);
background-image: url("http://www.skrenta.com/images/stackoverflow.jpg"), -webkit-gradient(linear, left top, left bottom, from(red), to(yellow));
background-image: url("http://www.skrenta.com/images/stackoverflow.jpg"), -moz-linear-gradient(top, red, yellow);
}
You could also define background positions and background size for the images.
I put together a blog post about some interesting things you can do with CSS3 gradients

you could simply type :
background: linear-gradient(
to bottom,
rgba(0,0,0, 0),
rgba(0,0,0, 100)
),url(../images/image.jpg);

my solution:
background-image: url(IMAGE_URL); /* fallback */
background-image: linear-gradient(to bottom, rgba(0,0,0,0.7) 0%,rgba(0,0,0,0.7) 100%), url(IMAGE_URL);

I always use the following code to make it work. There are some notes:
If you place image URL before gradient, this image will be displayed above the gradient as expected.
.background-gradient {
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -moz-linear-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -webkit-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -webkit-linear-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -o-linear-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, -ms-linear-gradient(135deg, #6ec575 0, #3b8686 100%);
background: url('http://trungk18.github.io/img/trungk18.png') no-repeat, linear-gradient(135deg, #6ec575 0, #3b8686 100%);
height: 500px;
width: 500px;
}
<div class="background-gradient"></div>
If you place gradient before image URL, this image will be displayed under the gradient.
.background-gradient {
background: -moz-linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: -webkit-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: -webkit-linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: -o-linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: -ms-linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
background: linear-gradient(135deg, #6ec575 0, #3b8686 100%), url('http://trungk18.github.io/img/trungk18.png') no-repeat;
width: 500px;
height: 500px;
}
<div class="background-gradient"></div>
This technique is just the same as we have multiple background images as describe here

I had an implementation where I needed to take this technique a step farther, and wanted to outline my work. The below code does the same thing but uses SASS, Bourbon, and an image sprite.
#mixin sprite($position){
#include background(url('image.png') no-repeat ($position), linear-gradient(#color1, #color2));
}
a.button-1{
#include sprite(0 0);
}
a.button-2{
#include sprite (0 -20px);
}
a.button-2{
#include sprite (0 -40px);
}
SASS and Bourbon take care of the cross browser code, and now all I have to declare is the sprite position per button. It is easy to extend this principal for the buttons active and hover states.

If you have strange errors with downloading background images use W3C Link checker: https://validator.w3.org/checklink
Here are modern mixins that I use (credits: PSA: don't use gradient generators):
.buttonAkc
{
.gradientBackground(#imageName: 'accept.png');
background-repeat: no-repeat !important;
background-position: center right, top left !important;
}
.buttonAkc:hover
{
.gradientBackgroundHover('accept.png');
}
.gradientBackground(#startColor: #fdfdfd, #endColor: #d9d9db, #imageName)
{
background-color: mix(#startColor, #endColor, 60%); // fallback
background-image: url("#{img-folder}/#{imageName}?v=#{version}"); // fallback
background: url("#{img-folder}/#{imageName}?v=#{version}") no-repeat scroll right center, -webkit-linear-gradient(top, #startColor 0%, #endColor 100%) no-repeat scroll left top; // Chrome 10-25, Safari 5.1-6
background: url("#{img-folder}/#{imageName}?v=#{version}") no-repeat scroll right center, linear-gradient(to bottom, #startColor 0%, #endColor 100%) no-repeat scroll left top;
}
.gradientBackgroundHover(#imageName)
{
.gradientBackground(#fdfdfd, #b5b6b9, #imageName);
}

If you want a gradient with a single background image in the center, you can do it with one line of code like this:
body {
background: url(logo.png) no-repeat fixed center center, linear-gradient(#00467f, #a5cc82) fixed;
}

Use background-blend-mode and rgba to mix the background image and color
This is what you need:
.myblendedbg {
background-image: url("some_image.png");
background-color: rgba(0, 0, 0, 0.85); /* use rgba for fine adjustments */
background-blend-mode: multiply;
}
If you adjust the alpha value of the rgba color value (it's at .85 in the example), you can control the transparency.
Also, background-blend-mode has other values you can play with to get some really creative results.
NOTE: background-blend-mode: color; fails on Firefox, while multiply works on all modern browsers

Here is a MIXIN that I created to handle everything that people might like to use:
.background-gradient-and-image (#fallback, #imgUrl, #background-position-x, #background-position-y, #startColor, #endColor) {
background: #fallback;
background: url(#imgUrl) #background-position-x #background-position-y no-repeat; /* fallback */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -webkit-gradient(linear, left top, left bottom, from(#startColor) #background-position-x #background-position-y no-repeat, to(#endColor)); /* Saf4+, Chrome */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -webkit-linear-gradient(top, #startColor, #endColor); /* Chrome 10+, Saf5.1+ */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -moz-linear-gradient(top, #startColor, #endColor); /* FF3.6+ */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -ms-linear-gradient(top, #startColor, #endColor); /* IE10 */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, -o-linear-gradient(top, #startColor, #endColor); /* Opera 11.10+ */
background: url(#imgUrl) #background-position-x #background-position-y no-repeat, linear-gradient(top, #startColor, #endColor); /* W3C */
}
This can be used like so:
.background-gradient-and-image (#f3f3f3, "../images/backgrounds/community-background.jpg", left, top, #fafcfd, #f2f2f2);
Hope you guys find this helpful.

I was trying to do the same thing. While background-color and background-image exist on separate layers within an object -- meaning they can co-exist -- CSS gradients seem to co-opt the background-image layer.
From what I can tell, border-image seems to have wider support than multiple backgrounds, so maybe that's an alternative approach.
http://articles.sitepoint.com/article/css3-border-images
UPDATE: A bit more research. Seems Petra Gregorova has something working here --> http://petragregorova.com/demos/css-gradient-and-bg-image-final.html

You could use multiple background: linear-gradient(); calls, but try this:
If you want the images to be completely fused together where it doesn't look like the elements load separately due to separate HTTP requests then use this technique. Here we're loading two things on the same element that load simultaneously...
Just make sure you convert your pre-rendered 32-bit transparent png image/texture to base64 string first and use it within the background-image css call (in place of INSERTIMAGEBLOBHERE in this example).
I used this technique to fuse a wafer looking texture and other image data that's serialized with a standard rgba transparency / linear gradient css rule. Works better than layering multiple art and wasting HTTP requests which is bad for mobile. Everything is loaded client side with no file operation required, but does increase document byte size.
div.imgDiv {
background: linear-gradient(to right bottom, white, rgba(255,255,255,0.95), rgba(255,255,255,0.95), rgba(255,255,255,0.9), rgba(255,255,255,0.9), rgba(255,255,255,0.85), rgba(255,255,255,0.8) );
background-image: url("data:image/png;base64,INSERTIMAGEBLOBHERE");
}

If you have to get gradients and background images working together in IE 9 (HTML 5 & HTML 4.01 Strict), add the following attribute declaration to your css class and it should do the trick:
filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0, startColorstr='#000000', endColorstr='#ff00ff'), progid:DXImageTransform.Microsoft.AlphaImageLoader(src='[IMAGE_URL]', sizingMethod='crop');
Notice that you use the filter attribute and that there are two instances of progid:[val] separated by a comma before you close the attribute value with a semicolon. Here's the fiddle. Also notice that when you look at the fiddle the gradient extends beyond the rounded corners. I don't have a fix for that other not using rounded corners. Also note that when using a relative path in the src [IMAGE_URL] attribute, the path is relative to the document page and not the css file (See source).
This article (http://coding.smashingmagazine.com/2010/04/28/css3-solutions-for-internet-explorer/) is what lead me to this solution. It's pretty helpful for IE-specific CSS3.

I resolve the problem in that way. I define Gradient in HTML and background image in the Body
html {
background-image: -webkit-gradient(linear, left bottom, right top, color-stop(0.31, rgb(227, 227, 227)), color-stop(0.66, rgb(199, 199, 199)), color-stop(0.83, rgb(184, 184, 184)));
background-image: -moz-linear-gradient(left bottom, rgb(227, 227, 227) 31%, rgb(199, 199, 199) 66%, rgb(184, 184, 184) 83%);
height: 100%
}
body {
background: url("http://www.skrenta.com/images/stackoverflow.jpg");
height: 100%
}

this is a background image with Gradient overlay, the 26% is the opacity and 7deg is the gradient position
CSS Gradient Generator
backgroundImage: `linear-gradient(7deg, rgba(2,0,36,1) 0%, rgba(39,17,68,1) 26%, rgba(10,19,20,0.49343487394957986) 100%), url('backgroundImg.jpeg')`,

I wanted to make span button with background image, background gradient combination.
http://enjoycss.com/ helped to do my work task. Only I have to remove some auto generated additional CSS. But it's really nice site build your scratch work.
#nav a.link-style span {
background: url("../images/order-now-mobile.png"), -webkit-linear-gradient(0deg, rgba(190,20,27,1) 0, rgba(224,97,102,1) 51%, rgba(226,0,0,1) 100%);
background: url("../images/order-now-mobile.png"), -moz-linear-gradient(90deg, rgba(190,20,27,1) 0, rgba(224,97,102,1) 51%, rgba(226,0,0,1) 100%);
background: url("../images/order-now-mobile.png"), linear-gradient(90deg, rgba(170,31,0,1) 0, rgba(214,18,26,1) 51%, rgba(170,31,0,1) 100%);
background-repeat: no-repeat;
background-position: 50% 50%;
border-radius: 8px;
border: 3px solid #b30a11;
}

For my responsive design, my drop-box down-arrow on the right side of the box (vertical accordion), accepted percentage as position. Initially the down-arrow was "position: absolute; right: 13px;". With the 97% positioning it worked like charm as follows:
> background: #ffffff;
> background-image: url(PATH-TO-arrow_down.png); /*fall back - IE */
> background-position: 97% center; /*fall back - IE */
> background-repeat: no-repeat; /*fall back - IE */
> background-image: url(PATH-TO-arrow_down.png) no-repeat 97% center;
> background: url(PATH-TO-arrow_down.png) no-repeat 97% center, -moz-linear-gradient(top, #ffffff 1%, #eaeaea 100%);
> background: url(PATH-TO-arrow_down.png) no-repeat 97% center, -webkit-gradient(linear, left top, left bottom, color-stop(1%,#ffffff), color-stop(100%,#eaeaea));
> background: url(PATH-TO-arrow_down.png) no-repeat 97% center, -webkit-linear-gradient(top, #ffffff 1%,#eaeaea 100%);
> background: url(PATH-TO-arrow_down.png) no-repeat 97% center, -o-linear-gradient(top, #ffffff 1%,#eaeaea 100%);<br />
> filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#eaeaea',GradientType=0 );
P.S. Sorry, don't know how to handle the filters.

I hope this is cross-browser enough:
(modified base from gradient editor with black to transparent vertical gradient on top of image)
background-image: url('YOURIMAGE.JPG');
background-image: -moz-linear-gradient(left, rgba(0,0,0,1) 0%, rgba(0,0,0,0) 100%),url('YOURIMAGE.JPG'); /* FF3.6-15 */
background-image: -webkit-linear-gradient(left, rgba(0,0,0,1) 0%,rgba(0,0,0,0) 100%),url('YOURIMAGE.JPG'); /* Chrome10-25,Safari5.1-6 */
background-image: linear-gradient(to right, rgba(0,0,0,1) 0%,rgba(0,0,0,0) 100%),url('YOURIMAGE.JPG'); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#000000', endColorstr='#00000000',GradientType=1 ), progid:DXImageTransform.Microsoft.AlphaImageLoader(src='YOURIMAGE.JPG', sizingMethod='crop'); /* IE6-9 */

As a sure method way, you can just make a background image that is say 500x5 pixels, in your css use:
background-img:url(bg.jpg) fixed repeat-x;
background:#<xxxxxx>;
Where xxxxxx corresponds with the color that matches the final gradient color.
You could also fix this to the bottom of the screen and have it match the initial gradient color.
