So far I have managed to get the background image to stretch:
XHTML:
<div id="background">
<img src="images/background.jpg" alt="Background" />
</div>
CSS:
#background
{
width: 100%;
height: auto;
position: fixed;
left: 0px;
top: 0px;
}
#background img
{
width: 100%;
height: 100%;
}
This works well, except the image is being displayed from the top when the height of the image exceeds the window height. This means that the top of the image is always displayed but the bottom is cut off. I want to change this so that the image is always displayed from the centre (so that both the top and bottom of the image is cut off and the centre is of the image is displayed).
Here is a good tutorial on creating a perfect full page background image. The same concept can be applied to any ol' div as well.
In general, images that are meant to be background images shouldn't appear in the markup itself. You're mixing presentation with content.
If having the img tag is not an absolute necessity remove it and add the following three lines in your #background class,
background-image:url(images/background.jpg);
background-position:center;
background-repeat:no-repeat;
The first line sets your background for the DIV. The second line positions it to centre always. The third line makes sure the background is not repeated which is what I assumed you needed by looking at your HTML structure.
More than happy to suggest further is required.

I have specified a div in my HTML code then defined the div in the stylesheet with a background image, height, width and a repeat-x value. My image does not repeat though.
This does work if I specify an image on the HTML file but then it overlaps the repeating image on the webpage.
CSS:
.header {
height: 120px;
width: 120px;
display:block;
background-image:url(logo.gif);
background-repeat: repeat-x;
background-size: contain;
}
HTML:
<div class="header" id="header">
<!--<img src="logo.gif" name="logo" width="181" height="119"
id="logo"/> -->
</div>
The expected results is my logo.gif being repeated to the right side of the page on the x axis. Actual results (as mentioned above) are that nothing comes up. The only time something comes up, is when I uncomment that HTML code above and then the image repeats (although its the CSS image repeating, not the HTML one) and there is a HTML image on top of it with the CSS image repeating beneath it, which looks weird because some of the logo sticks out from the HTML image. I tried to fix this problem by commenting out the HTML image because, hopefully, the CSS one would repeat but when commenting out the HTML img tag, the CSS one disappears too.
To get the effect that you want, first the width of the div needs to be bigger than height in order to see the repeat image in x-axis for example:
CSS:
.header {
height: 120px;
width: 460px; // <-- this needs to be bigger than height
display:block;
background-image:url(logo.gif);
background-repeat: repeat-x;
background-size: contain;
}
Here's the: example
I've started with this code. Results as expected, I have a image as the background of my first div, and it takes up the whole space.
<div id="Page1"></div>
<style>
height: 100vh;
background-image: url("/someImageLink");
background-size: 100vw 100vh;
</style
Every thing is fine, now I want to add...
position: fixed;
bottom: 0;
right: 0;
...in the css. Now the background image disappears all the way.
Is it possible to use a <img> to do the same thing as css background-image, or make it clip without it going blank?
Additional Information: I want a few of these divs in a row.They will appear and disappear as needed.
There will be buttons and text within the divs.
Your div does not have a width. It is necessary to add one now that you have changed its position from static to fixed
I have the following element in my initial page concept:
http://tinyurl.com/bcmcxp9
The ribbon is a PNG image. What I'd like to be able to do is position this image exactly over the border of a box-shadowed div (representing the page content), without affecting the page width.
I've tried a couple of techniques.
By using position:absolute, I've been able to achieve the visual effect I was looking for, but it brings up the dreaded horizontal scrollbars! I want the edge of the div (not the edge of the image) to represent the edge of the page.
#banner-ribbon {
background-image: url(ribbon-right.png);
background-repeat: no-repeat;
position: absolute:
width: 419px;
height: 114px;
left: 700px;
top: 400px;
}
By using a div that sits between the content wrapper and the background, I've been able to position the image in the right place without affecting the horizontal scrollbars (sort of, I might need a little javascript to absolute-position it relative to the center), but I can't raise the image's z-index above its child divs!
#banner-ribbon-wrapper {
background-image: url(ribbon-right.png);
background-repeat: no-repeat;
background-position: 90% 400px;
z-index: 70; /* does nothing */
}
Any ideas?
It sounds like the image is extending the boundaries of the page, causing the horizontal scroll bars. One way to fix this may be to set a width for your page and then hide anything that goes outside of it. Something like this may work for you:
body {
width: 100%;
overflow-x: hidden;
}
Example jsFiddle
Give your content div
position: relative
and to your ribbon
position: absolute
right:0
Make sure your image don't extend boundaries uncontrollably.

The PNG image is the sidebar, and the black part is the CSS background, the PNG's alpha seems to override the black box.
When I change the image's opacity, you can see the box continues through the entire image, but is still overridden and I double-checked the sidebar's transparency, but it's set up properly.
It does this on Google Chrome as well as Firefox.
Relevant CSS:
.sidebar{
background: url('side1.png') lightgray 10% 50%;
background-repeat: no-repeat;
background-size: 100%;
height: 600px;
width: 173px;
z-index:1;
float:left;
position:relative;
opacity:0.5;
}
.header{
background: black;
background-position: top right;
float:right;
width:100%;
height: 200px;
z-index:0;
position:absolute;
}
Relevant HTML:
<div class="sidebar">
<img src="images/pic1.png" class="icon">
</div>
<div class="header"></div>
This appears to be just a simple case of the division going back behind the floated content. Most people don't realize that just because there is floated content there, the division still expands back behind it all the way to the edge, like it normally would if the floated content wasn't there.
That division is taking up its maximum amount of available space like it is expected too. The floated content is only pushing the content, which at this point, there isn't any. Making your sidebar partially opaque, this issue becomes visible as you can see that box behind your image now. A quick fix, per say, would be to add a margin to the division to push it out from behind the sidebar, like so:
.header {
margin-left: 173px; /* The width of your sidebar */
}
Note, however, that you would have to apply this margin to the left side of all your block-level elements that need pushed out from under. So it would make sense to put all the right content into a single box that gets pushed out, to prevent confusion.
Edit: The reason your black background doesn't pull through on the sidebar image is that you're setting it's background to light grey here:
background: url('side1.png') lightgray 10% 50%;
This will put a light grey background behind the image rather than letting the transparent part of your image go through to whatever is behind it. Try removing it:
background: url('side1.png') 10% 50%;
See the jsFiddle example.
I want to display images in a 144px x 144px div element.
Images are always larger than 144px and so I want to zoom scale them. By that I mean that the smallest side will touch the edge of the div, cutting a bit from the other side - the opposite of letterbox.
How can I do this and have it work on older browsers like IE as well?
EDIT:
Changed the image, the first was wrong, sorry.
Resize the image so that inside the div there is no space without image
My first answer addressed intentionally blocking out the part of the image while intentionally keeping the space occupied. If you just want part of the image visible with no space or anything else taken up, the best option will be to use CSS Sprite techniques.
Here's an example:
HTML (copy and paste into your own file for a full test):
<html>
<head>
<style type="text/css">
.clippedImg {
background-image: url("http://www.grinderschool.com/images/top_main.jpg");
background-position: -75px -55px;
height: 100px;
width: 235px;
}
</style>
</head>
<body>
<div class='clippedImg'> </div>
</body>
</html>
CSS (this is really the key):
.clippedImg {
background-image: url("http://www.grinderschool.com/images/top_main.jpg");
background-position: -75px -55px;
}
You can adjust the position numbers to get exactly the portion and size of the image that you want.
Note also that if you want a black box around this, it's even easier than the other post I made. Just put a parent div around this one:
<div class='blackBox'>
<div class='clippedImg'> </div>
<div>
With a padding and width set to create the black-box effect you want:
.blackBox {
background-color: black;
padding: 0 20px;
width: 235px;
}
Set only the width of the image to 144px in CSS or in the attribute. The height will scale automatically. I'm fairly certain this works as low as IE 6. I'm not certain about anything older than that.
If I read your question right, you aren't trying to resize the image, but rather to actually cut off part of the image. If you just want to resize the image, then follow the other answers about that.
The simplest way I can think of to actually cut off the image this is to add <div class='blockOut'> </div> and then use CSS to place & size the div, make it's color match the background color of your page, and put it in front of the image. Example CSS:
.blockOut {
position: relative;
top: -100px;
left: 100px;
background-color: white;
z-index: 2; //this is the important part for putting this div in front of the other one
}
Edit: Note that since you added an example showing that you want all sides blacked out, this would require separate divs for blacking out the top, each side, and the bottom. Also, if you want part of the image to show through (as it does in your example) you can use CSS transparency options.
div{height:114px;width:114px;overflow:hidden;}
div img{position:relative;left:-100px /*or whatever you want. can change it with js*/;top:-100px;}
that is masking to only show a part of the img, as you say in the title. but in the description says you want to resize the img. decide yuorself
to do what you want with css, you should use max-height:144px;max-width:144px. but ie6 doesn't implements those simple properties, so you'll have to use js
