CSS rollovers don't work in Safari???

[pulleys]

My CSS rollovers work in everything but Safari. I can't figure out why. Here is my code contained in my style sheet.

a#rollover:hover {
display:block;
width:125px;
height:12px;
background-color:#FFCC00;
}

and the ID gets added in the html file like this for example:

<a href="../projects/projects.html" id="rollover">PROJECTS</a>

Any idea's?

Thanks for the help in advanced.
