Hiya Chris.
Okay, here is your solution:
Contain the content of each half and provide it with an ID. For example.
Code:
<div id="blue">
blue half
<a href="#">link</a>
</div>
<div id="white">
white half
<a href="#">link</a>
</div>
The CSS will look something like this. The second section (Link Styles) is what you're most interested in.
Code:
/* Site Structure */
#blue {
float: left;
width: 300px;
background-color: blue;
}
#white {
float: left;
background-color: white;
}
/*Link Styles*/
#blue a:link, #blue a:active, #blue a:visited {
color: white;
}
#blue a:hover {
color: green;
}
#white a:link, #white a:active, #white a:visited {
color: blue;
}
#white a:hover {
color: red;
}
Let me know how you fare. I'd rather you post here instead of emailing me, though. I'm sorry for being somewhat unreachable, but it's dissertation season.
