I have an image set as a background image of a div. The DIV size is changing and inside their is the image which is a gradient.
CSS:
#scroller_shadow{
background-image:url(../img/ui/shadow.png);
background-repeat:repeat-x;
background-position:top;
}
I need a cross-browser solution for making the image fit the height of the div in the y-axis only, keeping the repeat-x. The DIV is being resized dynamically via JQuery.
Their might be a cross-browser option using JQuery. I don't mind using scripts to achieve that in order to get cross-browser support (IE7+). I don't want to stretch the image because it loses the intensity when you stretch the image on the x-axis, making a semi-transparent png image almost transparent.
Thanks.
I had this problem too. It's easy in most browsers, but IE8 and below it's tricky.
Solution for modern (anything not IE8 and below) browsers:
#scroller_shadow {
background: url(../img/ui/shadow.png) center repeat-x;
background-size: auto 100%;
}
There are jQuery plugins that can mimic background-size for IE8 and below, specifically backgroundSize.js but it doesn't work if you want it to repeat.
Anyways thus begins my terrible hack:
<div id="scroller_shadow">
<div id="scroller_shadow_tile">
<img src="./img/ui/shadow.png" alt="" >
<img src="./img/ui/shadow.png" alt="" >
<img src="./img/ui/shadow.png" alt="" >
...
<img src="./img/ui/shadow.png" alt="" >
</div>
</div>
Make sure to include enough <img>
's to cover the area needed.
CSS:
#scroller_shadow {
width: 500px; /* whatever your width is */
height: 100px; /* whatever your height is */
overflow: hidden;
}
#scroller_shadow_tile {
/* Something sufficiently large, you only to make it unreasonably wide if the width of the parent is dynamic. */
width: 9999px;
height: 100%;
}
#scroller_shadow_tile img {
height: 100%;
float: left;
width: auto;
}
Anyways, the idea is to create the stretch effect from the images.
