Comments on: Extremely efficient image rollovers using CSS sprites and NO Javascript

If I may suggest something :

a.sprite{
background:url(/images/sprite.png);
width:102px;
height:26px;
display:block;
}

a:link.rollover,a:visited.rollover{
background-repeat:no-repeat;
background-position:left top;
}

a:hover.rollover,a:active.rollover{
background-repeat:no-repeat;
background-position:left bottom;
}

…

this way you decide with the second class if the image is rollover. And with the position “top” and “bottom”, you don’t have to specify an exact amount of pixels. Infact, you could give every hyperlink the rollover class, because if the image has the same height of the “sprite”, the image will not move.

hmmm… Why do you need “# padding-top:20px; ” when you have background position as 0?

@Art, I’m not sure if I understand your question. It scales like any other image based rollover would.

Great solution! How well does it scale though? If the user enlarges the page, will the link’s image scale correctly along with the page text?

good article, I find topic similar all over internet, but not yet find a topic that talk deep into using sprite of large scale, which is a major hedache if you try to ram 50+ image in one background, and still maintain the image size edge and the efficiency.

@billy, you must mean the javascript:void(0); … that doesn’t affect the rollover. It’s just a quick hack to keep the link from going anywhere.

@billy, are you sure about that? ;)

#header ul li a:link{ background: transparent url(/images/sprite-aaa.png) no-repeat scroll 0 -63px; }

#header ul li a:hover { background-position: 0 0; }

I call shenanignas! Looking at your source code I see javascript for your example rollovers. Cheater!
