Background-position not working for CSS sprites
I can't get the "background-position" CSS to target a specific part of the image, I've set the position and can get all the images to load but the area specified does not show. I have written this code so far to no avail:
<head>
<style type="text/css">
ul#links {
list-style: none;
}
ul#links li a{
float: left;
padding: 40px;
background: url('http://static.tumblr.com/wgijwsy/ixYlr91ax/sprite_colored.png') no-repeat;
}
#customlink {
width: 24px;
height: 24px;
background-position: -0px -0px ;
background-repeat: no-repeat;
}
#rss {
width: 24px;
height: 24px;
background-position: -24px -0px;
background-repeat:no-repeat;
}
#facebook {
width: 24px;
height: 24px;
background-position: -0px -24px;
background-repeat:no-repeat;
}
#flickr {
width: 24px;
height: 24px;
background-position: -24px -24px;
background-repeat:no-repeat;
}
#twitter {
width: 24px;
height: 24px;
background-position: -0px -48px;
background-repeat:no-repeat;
}
#linkedin {
width: 24px;
height: 24px;
background-position: -24px -48px;
background-repe开发者_JAVA百科at:no-repeat;
}
#google {
width: 24px;
height: 24px;
background-position: -0px -72px;
background-repeat:no-repeat;
}
#foursquare {
width: 24px;
height: 24px;
background-position: -72px -0px;
background-repeat:no-repeat;
}
</style>
</head>
<body>
<ul id="links">
<h2>Social Networks</h2>
<li><a href="" id="customlink"></a></li>
<li><a href="" id="rss"></a></li>
<li><a href=""id="facebook"></a></li>
<li><a href=""id="flickr"></a></li>
<li><a href="" id="twitter"></a></li>
<li><a href="" id="linkedin"></a></li>
<li><a href=""id="google"></a></li>
<li><a href=""id="foursquare"></li>
</ul>
</body>
</html>
Due to ul#links li a being more specific than for example #facebook, the background rule inside ul#links li a is overriding the background-position on #facebook.
Splitting background into background-image and background-repeat is a simple fix:
ul#links li a{
float: left;
background-image: url('http://static.tumblr.com/wgijwsy/ixYlr91ax/sprite_colored.png');
background-repeat: no-repeat;
width: 24px;
height: 24px;
}
#facebook {
background-position: -0px -24px;
}
Think you were getting a bit confused between styling the LI's and the actual A's, things are overriding what you've set.
here is a working fiddle for you - hope this points you in the correct direction :)
