body {
background-image: url('cloud.png');
background-color: rgba(255, 255, 255, 0.6);
}
I tried using the above to produce a semi-transparent white background above a background-image. It doesn't work, only the background image is shown and the background-color appears to be ignored. How can I adjust the opacity of a body background image?
You can use the css "before" pseudo class to create the white overlay and place before all the content in your DOM. Add z-index:-1 to ensure it doesn't sit on top of other elements:
body {
background: url("image.jpg");
}
body:before {
content: "";
display: block;
position: fixed;
width: 100%;
height: 100%;
left: 0;
top: 0;
z-index: -1;
background-color: rgba(255, 255, 255, 0.6);
}
jsfiddle
background-color is placed underneath background-image, not above it (when rendered in the web-browser). To put a semi-transparent white block over an image, you will need to place another different HTML element on top of it with background-color.
I've done this using two separate images when announcing a special sale. One is the permanent image in the background and the other is a temporary sale image with semi-transparent background floated over the other image, that can be easily removed after the sale is over. The main div holding the background image needs to be Position:relative so you can position the semi-transparent image with position:absolute over the other image.
Here is the HTML:
<div class="tempsale" >
<img src="images/ULR FOR YOUR BANNER GOES HERE.jpg" width="800" height="100" border="0" alt="banner">
<div class="tempsaletext">
<img src="images/URL FOR YOUR TEMPORARY SALE GOES HERE.jpg" width="500px" height="80px" alt="Sale">
</div>
</div>
Here is the CSS:
.tempsale {
text-align:center;
position:relative;
}
.tempsaletext {
positon:absolute;
top:10px;
left:20%;
}

Is it possible to apply a css blend mode to an element in a different div?
E.g, I have a large background hero image in one div. Above that image (in a different div) I have a blue semi-transparent box with text in it. This transparent box is what I would like to apply a blend to, but it seems to not work perhaps because they are not in the same div, like in the example https://css-tricks.com/basics-css-blend-modes/
I am working in wordpress, so it will be a bit hard to re-structure the HTML in order to put the image and the colored box in the same div.
Does anybody know of a trick I can use to achieve this method?
Thanks in advance!
Use mix-blend-mode.
DEMO:
http://plnkr.co/edit/R5TBohMs1jKfsPj7zcXt?p=preview
There are two ways to use blend-modes:
background-blend-mode: If both the background are in same div, then this property can be used.
mix-blend-mode: When you want to blend background of 2 different elements, then you can use the mix-blend-mode property.
code:
HTML:
<div class="wrapper">
<div class="first"></div>
<div class="second"></div>
</div>
CSS:
div.wrapper {
position: relative;
}
div.first,
div.second {
width: 300px;
height: 200px;
position: absolute;
}
div.first {
background: url(http://images.all-free-download.com/images/graphicthumb/male_lion_193754.jpg) 0 0 no-repeat;
z-index: 9;
top: 0px;
left: 0px;
}
div.second {
background: url(http://images.all-free-download.com/images/graphicthumb/canford_school_drive_dorset_514492.jpg) 0 0 no-repeat;
z-index: 10;
mix-blend-mode: difference;
top: 30px;
left: 120px;
}
Here is a trick:
you can add both divs in a single div.
Then in css You can add the two backgrounds for a single div. This way, you can use the background-blend-mode property to blend the two images.
Here's an example: https://jsfiddle.net/4mgt8occ/3/
You can use :after or :before to create another element in the img-div. Then set the background color with rgba(). The 0.2 here is the opacity of the background color. For the text div, you don't have to do anything about it.
div#wrapper::after {
background-color: rgba(216, 223, 228, 0.2);
display: block;
width: 100%;
height: 100%;
content: ' ';
}
I am trying to create a transparent border for my image and place it over the image using CSS.
For example please see the image below:
To achieve this I tried the following code but I am facing the following problems:
The border is not over the image; its around the image and not allowing the image to fit 100% inside the parent div
To Make the border transparent I used "opacity" but its making the image transparent too which I don't want.
You can check the code live here: http://jsfiddle.net/6GK45/
I could create a div and made the border color transparent and then place it over the image but the problem is the width of my image is fixed (277px) but the height is not. So this will not work for me.
Could you please tell me how to create the transparent image border and place it over the image just like in the image above.?
HTML:
<div class="box" >
<img class="lightbox" src="myimage.jpg" />
This is text
</div>
CSS
.box {
width:277px;
background:#FCFBDF;
}
.lightbox {
border: 5px solid red;
z-index:999;
opacity:0.3;
}
img {
width:277px;
}
How's this - it uses :after to create a pseudo-element which places the border on top of the image, not outside it. http://jsfiddle.net/6GK45/8/
.imgWrap:after{
content:"";
position:absolute;
top:0; bottom:0; left:0; right:0;
opacity:0.5;
border:5px solid red;
}
UPDATE: If it's important to preserve the ability to right-click on the image, you can do it like this with an additional wrapper: http://jsfiddle.net/6GK45/24/
For anyone still googling for this: It is possible to achieve this effect with CSS only by using the outline property:
img {
outline: 15px solid rgba(255, 0, 0, .75);
outline-offset: -15px;
}
<img src="http://i.dailymail.co.uk/i/pix/2012/12/04/article-2242647-0F79C42300000578-201_634x429.jpg" width=250 />
As Donovan said, rgba for the border-color – but the border on an element containing the image, and then the image “pulled” outwards under the border using a negative margin and z-index – like this, http://jsfiddle.net/6GK45/7/
<div class="box" >
<span class="lightbox"><img …></span>
…
</div>
.lightbox{
display:block;
width:267px;
border:5px solid rgba(255,255,255,.75);
}
.lightbox img{
display:block;
width:277px;
margin:-5px;
position:relative;
z-index:-1;
}
If you want a border with opacity, you can use RGBA code. The 'A' signify alpha, so you can modify opacity.
border: 5px solid rgba(255,0,0, 0.3) ;
You can use z-index to put your box with border above your image if you put image and box in position absolute, relative.
I updated your fiddle. http://jsfiddle.net/6GK45/21/
What you need to do is set the image as the background of the parent div and then adjust the width/height of the child div to hug the image accordingly.

I need to figure out how to overlay an image of my logo on top of another repeating image that is being used as a background for the nag bar at the top of my site.
The CSS for the nag bar image looks like this:
.header {
background:url(../images/bg-header.jpg) repeat-x;
height:125px;
is there a way to add another image on top of this and have it aligned to the left side of the underlying image?
Something like this?
http://jsfiddle.net/aJEwZ/
<style>
.nav {
background: url(http://www.psdgraphics.com/file/light-wooden-background.jpg) repeat-x;
height: 250px;
width: 500px;
border:1px solid black;
}
img {
padding:20px;
}
</style>
<div class='nav'>
<img src="http://a.deviantart.net/avatars/h/a/haz-elf.jpg?1" />
hello</div>
Here you go.
here's a DEMO
and here's the CODE
Here's the css
.header {
background: url("http://fc04.deviantart.net/fs70/i/2013/266/7/3/sydneigh_logo_by_robberbutton-d6nmaox.png") top left no-repeat ,url("http://subtlepatterns.com/patterns/sandpaper.png") repeat-x;
background-size: 571px 125px, auto;
height:125px;
width: 100%;
}
notice how the background attribute has two shorthand backgrounds with images written out seperated by a comma. The first image is on top of the second image and so on.
The first property of attribute background-size only applies to the first property in the background attribute (the first image in the declared background attribute.) The second applies to the second image in the background attribute.
This works the same way with other background-properties such as background-repeat, and background-image.
Here's an article on having multiple background images:
http://www.css3.info/preview/multiple-backgrounds/
I have used a background image on the webpage and used this code in the css which makes it nicely resize when browser is resized.
body{
background: url("images/back.jpg") no-repeat ;
background-size: cover;
}
I need to place some other image on top of the background image at a specific place ( vase on table) .but when i do that then the background gets resized but the vase image remains in the same place and same size when browser is resized as shown in second picture below.
see the vase in these two images
browser in full size
resized browser
how can i make the vase image also get resized just like the background
I recently ran into exactly the same issue creating a hidden object game which needed images placed on top of a background image to maintain their position regardless of browser dimensions.
Here's what I did:
You can include a template version of the background image as an actual <img> with visibility:hidden (so it's not visible but still takes up it's space in the DOM and base the size (and background image size) based on that.
HTML:
<div class="image-container">
<img src="http://www.w3.org/html/logo/downloads/HTML5_Logo_512.png" class="img-template">
<div class="item"></div>
</div>
CSS:
/* This is your container with the background image */
.image-container {
background:url('http://www.w3.org/html/logo/downloads/HTML5_Logo_512.png') no-repeat;
background-size:100%;
overflow-x: hidden;
position:relative;
}
/* This is the template that resizes the DIV based on background image size */
img.img-template {
visibility: hidden;
width:100%;
height:auto;
}
/* This is the item you want to place (plant pot) */
.item {
position: absolute;
left: 14.6%;
bottom: 80.3%;
width: 15%;
height: 15%;
background: yellow;
border: 2px solid black;
}
Here is a working example: http://jsfiddle.net/cfjbF/3/
Try making the image relative position and setting the alignment manually.
http://jsfiddle.net/cfjbF/1/
<head>
<style>
body {
background: #000000;
}
#image1 {
background: #008000;
position: relative;
left: 50px;
height: 50px;
width: 50px;
}
</style>
</head>
<body>
<div id="image1"></div>
</body>

I have a site design that uses background images and textures as a feature of the site.
See background design concept here: http://www.flickr.com/photos/54233587#N03/6145240784/in/photostream
The background is intended to work like this:
The page background has a tiled pattern (or on some pages there will be solid background colour).
The top part of the background is overlayed with a background image. The background image is a large image (2000px wide) and needs to be centred in the window. Depending on the page, the height of the image will crop from the bottom (that is, on one page the image may need to be 400px, while on others it may be 450px). This background image also has a CSS3 box-shadow applied so there is a slight shadow at the bottom of the image. This background image cannot use a fixed position - that is, it should move with the page if it is scrolled.
All other page content sits on top of the background in a centered div, indicated by the black box in the screenshot.
I have tried to achieve this by targeting the HTML5 html node for the tiled background.
html {
background: url(../img/pegboard.jpg) repeat center;
}
Then, for the overlaying background image I've been using a div element to insert an image.
<div id="bgimage"><img src="mybgimage.jpb"></div>
Then styling the img to try and center, not be fixed when scrolling, and resize the div to crop image from bottom. All without much success.
Thanks.
I would do something like this.
HTML:
<div id="bgimage"></div>
<div id="content">
Actual content goes here.
</div>
CSS:
body {
background: url(../img/pegboard.jpg) repeat center;
}
#bgimage {
position: absolute;
top: 0;
left: 0;
right: 0;
background: url(../img/mybgimage.jpg) no-repeat center;
height: 400px;
box-shadow: 0 5px 5px -5px #000;
}
#content{
margin: 0 auto;
width: 960px;
height: 1000px;
background: #000;
filter: alpha(opacity=50);
opacity: 0.5;
}
