I am a student and I'm having an issue with one of the video tutorials regarding using a background image. I followed the code exactly as is in the video but it's not producing the same results. It just keeps showing the image tiled throughout the whole web-page. Any help would be appreciated.
<style type="text/css">
body {
background-image:url(goku.jpg);
background-repeat:no-repeat;
background-attachment: 50% 60px;
}
</style>
Your background-attachment value is invalid, and you should add a background-sizesetting. In the snippet below I used cover to cover the whole screen, but you can also use other sizes. But then you should also add background-position
EDIT after comment: Well then just change to background-position: 50% 50%;. The image - if you don't use background-size will be displayed at its original size, and with that setting, be centered horizontally and vertically. If you don't like the vertical centering, change the second value to whatever you like, also in pixels, if you want.
html,
body {
margin: 0;
height: 100%;
}
body {
background-image: url(https://placehold.it./240x180/fb4);
background-repeat: no-repeat;
background-attachment: fixed;
background-position: 50% 50%;
}

I'm reading news on this page mostly on my mobile device:
link
The big banner right of the logo is not scaling properly on the mobile device.
So when you resize the window and make it smaller everything is resizing except the banner.
Im learning php, css and just wondering how this could be solved. Ive checked also on stackoverflow and find something like:
img {
max-width: 100%;
height: auto;
width: auto\9; /* ie8 */ }
I've tried this also in the dev. mode of google chrome but it desnt work.
Is this solvable with the provided data from the dev mode?
Code looks like:
<div style="position:relative;
width:728px; height:90px; z-index:10;
background-image: url(http://www.image.jpg);">
Based on your code, the banner is implemented as background image, not an IMG element. To make background image scaled so that it's entirely visible, use background-size: contain. So your user styles could be like this:
.site-header-banner > DIV {
background-size: contain;
background-repeat: no-repeat; // To disable repeating background image.
max-width: 100%;
}
You can use it as a background with the following properties:
background-repeat: no-repeat;
background-position: center center;
background-size: cover;

You can define a fixed size to DIV containing image background and change it by media query.
In my jQuery mobile 1.4.0 app I have a Page which contains a list view the Problem is that when I have added a background image for this page as the list elements are becoming larger as the background stretchs with the content and this apears clearly on mobile devices more than jsFiddle ,this is my jsfiddle .
How can I make the background image to be fullscreen and fixed , not stretched with the content? Please help me ..
Here How I add a background image to my Page:
#EmPListPage{
background-image: url('http://images2.layoutsparks.com/1/218610/just-ducky-dots- pinky.gif') !important;
background-repeat: no-repeat;
background-size: 100% 100%;
}
#PageContent{
background: transparent ;
}
In my case the solution was to use contain, like this:
.ui-page {
background: #000;
background-image: url("http://bettingmasters.info/wp-content/uploads/2013/11/19757-football-stadium-1920x1200-sport-wallpaper.jpg");
background-size: contain;
}
You will want to attach the background image to the document body instead of your container div. Using your CSS in the fiddle:
body {
background-image: url('http://images2.layoutsparks.com/1/218610/just-ducky-dots-pinky.gif') !important;
background-repeat: no-repeat;
background-size: 100% 100%;
}
#EmPListPage, #PageContent{
background: transparent ;
}

I have three problems:
When I tried to use a background image in a smaller size div, the div shows only part of image. How can I show the full or a specific part of image?
I have a smaller image and I want to use in a bigger div. But don't want to use repeat function.
Is there any way in CSS to manipulate the opacity of an image?
Resize the image to fit the div size.
With CSS3 you can do this:
/* with CSS 3 */
#yourdiv {
background: url('bgimage.jpg') no-repeat;
background-size: 100%;
}
How Do you Stretch a Background Image in a Web Page:
About opacity
#yourdiv {
opacity: 0.4;
filter: alpha(opacity=40); /* For IE8 and earlier */
}
Or look at CSS Image Opacity / Transparency
To automatically enlarge the image and cover the entire div section without leaving any part of it unfilled, use:
background-size: cover;
This worked perfectly for me
background-repeat: no-repeat;
background-size: 100% 100%;
Try below code segment, I've tried it myself before :
#your-div {
background: url("your-image-link") no-repeat;
background-size: cover;
background-clip: border-box;
}
Rather than giving background-size:100%;
We can give background-size:contain;
Check out this for different options avaliable: http://www.css3.info/preview/background-size/
This will work like a charm.
background-image:url("http://assets.toptal.io/uploads/blog/category/logo/4/php.png");
background-repeat: no-repeat;
background-size: contain;
I agree with yossi's example, stretch the image to fit the div but in a slightly different way (without background-image as this is a little inflexible in css 2.1). Show full image:
<div id="yourdiv">
<img id="theimage" src="image.jpg" alt="" />
</div>
#yourdiv img {
width:100%;
/*height will be automatic to remain aspect ratio*/
}
Show part of the image using background-position:
#yourdiv
{
background-image: url(image.jpg);
background-repeat: no-repeat;
background-position: 10px 25px;
}
Same as the first part of (1) the image will scale to the div so bigger or smaller will both work
Same as yossi's.
I want that my background image stretch and scale depending on the browser viewport size.
I've seen some questions on Stack Overflow that do the job, like Stretch and scale CSS background for example. It works well, but I want to place the image using background, not with an img tag.
In that one an img tag is placed, and then with CSS we tribute to the img tag.
width:100%; height:100%;
It works, but that question is a bit old, and states that in CSS 3 resizing a background image will work pretty well. I've tried this example the first one, but it didn't work out for me.
Is there a good method to do it with the background-image declaration?
CSS3 has a nice little attribute called background-size:cover.
This scales the image so that the background area is completely covered by the background image while maintaining the aspect ratio. The entire area will be covered. However, part of the image may not be visible if the width/height of the resized image is too large.
You could use the CSS3 property to do it quite nicely. It resizes to ratio so no image distortion (although it does upscale small images). Just note, it's not implemented in all browsers yet.
background-size: 100%;
Using the code I mentioned...
HTML
<div id="background">
<img src="img.jpg" class="stretch" alt="" />
</div>
CSS
#background {
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
z-index: -1; /* Ensure div tag stays behind content; -999 might work, too. */
}
.stretch {
width:100%;
height:100%;
}
That produces the desired effect: only the content will scroll, not the background.
The background image resizes to the browser viewport for any screen size. When the content doesn't fit the browser viewport, and the user needs to scroll the page, the background image remains fixed in the viewport while the content scrolls.
With CSS 3 it seems this would be a lot easier.
CSS:
html,body {
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover; /* For WebKit*/
-moz-background-size: cover; /* Mozilla*/
-o-background-size: cover; /* Opera*/
background-size: cover; /* Generic*/
}
background-size: 100% 100%;
stretches the background to fill the entire element on both axes.
The following CSS part should stretch the image with all browsers.
I do this dynamically for each page. Therefore I use PHP to generate its own HTML tag for each page. All the pictures are in the 'image' folder and end with 'Bg.jpg'.
<html style="
background: url(images/'.$pic.'Bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=\'images/'.$pic.'Bg.jpg\', sizingMethod=\'scale\');
-ms-filter: \"progid:DXImageTransform.Microsoft.AlphaImageLoader(src=\'images/'.$pic.'Bg.jpg\', sizingMethod=\'scale\')\
";>
If you have only one background picture for all pages then you may remove the $pic variable, remove escaping back-slashes, adjust paths and place this code in your CSS file.
html{
background: url(images/homeBg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='images/homeBg.jpg', sizingMethod='scale');
-ms-filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='images/homeBg', sizingMethod='scale');
}
This was tested with Internet Explorer 9, Chrome 21, and Firefox 14.
Use this CSS:
background: url('img.png') no-repeat;
background-size: 100%;
You can actually achieve the same effect as a background image with the img tag. You just have to set its z-index lower than everything else, set position:absolute and use a transparent background for every box in the foreground.
You can add this class into your CSS file.
.stretch {
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
It works in:
Safari 3 or later
Chrome Whatever or later
Internet Explorer 9 or later
Opera 10 or later (Opera 9.5 supported background-size, but not the keywords)
Firefox 3.6 or later (Firefox 4 supports non-vendor prefixed version)
It is explained by CSS tricks: Perfect Full Page Background Image
Demo: https://css-tricks.com/examples/FullPageBackgroundImage/progressive.php
Code:
body {
background: url(images/myBackground.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
In order to scale your images appropriately based on the container size, use the following:
background-size: contain;
background-repeat: no-repeat;
I use this, and it works with all browsers:
<html>
<head>
<title>Stretched Background Image</title>
<style type="text/css">
/* Remove margins from the 'html' and 'body' tags, and ensure the page takes up full screen height. */
html, body {height:100%; margin:0; padding:0;}
/* Set the position and dimensions of the background image. */
#page-background {position:fixed; top:0; left:0; width:100%; height:100%;}
/* Specify the position and layering for the content that needs to appear in front of the background image. Must have a higher z-index value than the background image. Also add some padding to compensate for removing the margin from the 'html' and 'body' tags. */
#content {position:relative; z-index:1; padding:10px;}
</style>
<!-- The above code doesn't work in Internet Explorer 6. To address this, we use a conditional comment to specify an alternative style sheet for IE 6. -->
<!--[if IE 6]>
<style type="text/css">
html {overflow-y:hidden;}
body {overflow-y:auto;}
#page-background {position:absolute; z-index:-1;}
#content {position:static;padding:10px;}
</style>
<![endif]-->
</head>
<body>
<div id="page-background"><img src="http://www.quackit.com/pix/milford_sound/milford_sound.jpg" width="100%" height="100%" alt="Smile"></div>
<div id="content">
<h2>Stretch that Background Image!</h2>
<p>This text appears in front of the background image. This is because we've used CSS to layer the content in front of the background image. The background image will stretch to fit your browser window. You can see the image grow and shrink as you resize your browser.</p>
<p>Go on, try it - resize your browser!</p>
</div>
</body>
</html>
I wanted to center and scale a background image, without stretching it to the entire page, and I wanted the aspect ratio to be maintained. This worked for me, thanks to the variations suggested in other answers:
INLINE IMAGE: ------------------------
<div id="background">
<img src="img.jpg" class="stretch" alt="" />
</div>
CSS ----------------------------------
html {
height:100%;
}
#background {
text-align: center;
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
z-index: -1;
}
.stretch {
margin: auto;
height:100%;
}
Thanks!
But then it was not working for the Google Chrome and Safari browsers (stretching worked, but the hight of the pictures was only 2 mm!), until someone told me what lacks:
Try to set height:auto;min-height:100%;
So change that for your height:100%; line, gives:
#### #background {
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
z-index: -1;
}
.stretch {
width:100%;
height:auto;
min-height:100%;
}
Just before that newly added code I have this in my Drupal Tendu themes style.css:
html, body{height:100%;}
#page{background:#ffffff; height:auto !important;height:100%;min-height:100%;position:relative;}
Then I have to make a new block within Drupal with the picture while adding class=stretch:
< img alt="" class="stretch" src="pic.url" />
Just copying a picture with the editor in that Drupal block doesn't work; one has to change the editor to non-formatted text.
I agree with the image in absolute div with 100% width and height. Make sure you set 100% width and height for the body in the CSS and set margins and padding to zero. Another issue you will find with this method is that when selecting text, the selection area can sometimes encompass the background image, which has the unfortunate effect of making the full page have the selected state. You can get round this by using the user-select:none CSS rule, like so:
<html>
<head>
<style type="text/css">
html,body {
height: 100%;
width: 100%
margin: none;
padding: none;
}
#background {
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
z-index: -99999;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-o-user-select: none;
user-select: none;
}
#background img {
width: 100%;
height: 100%;
}
#main{ z-index:10;}
</style>
</head>
<body>
<div id="main">
content here
</div>
<div id="background"><img src="bg.jpg"></div>
</body>
</html>
Again, Internet Explorer is the bad guy here, because it doesn't recognise the user-select option - not even Internet Explorer 10 preview supports it, so you have the option of either using JavaScript to prevent background image selection (for example, http://www.felgall.com/jstip35.htm ) or using CSS 3 background-stretch method.
Also, for SEO I would put the background image at the bottom of the page, but if the background image takes too long to load (that is, with a white background initially), you could move to the top of the page.
I used a combination of the background-X CSS properties to achieve the ideal scaling background image.
background-size: cover;
background-repeat: no-repeat;
background-position: center;
background-attachment: fixed;
This makes the background always cover the entire browser window and remains centered when scaling.
Use the Backstretch plugin. One could even have several images slide. It also works within containers. This way for example one could have only a portion of the background been covered with an background image.
Since even I could get it to work proves it to be an easy to use plugin :).
The following worked for me.
.back-ground {
background-image: url("../assets/background.png");
background-size: 100vw 100vh;
}
that worked to cover the entire background on different dimensions
If you want to have the content centered horizontally, use a combination like this:
background-repeat: no-repeat;
background-size: cover;
background-position: center;
This will look beautiful.
Use this CSS:
background-size: 100% 100%
You can use the border-image : yourimage property to scale the image up to the border. Even if you give the background-image, the border image will be drawn over it.
The border-image property is very useful if your style sheet is implemented somewhere which doesn't support CSS 3. If you are using Google Chrome or Firefox, then I recommend the background-size:cover property itself.
Do you want to achieve this just using one image? Because you can actually make somewhat similar to a stretching background using two images. PNG images for instance.
I've done this before, and it's not that hard. Besides, I think stretching would just harm the quality of the background. And if you add a huge image it would slow down slow computers and browsers.
