menu, or in your case, ul properties are the same for every page, so when you need to modify these properties for just one page, the way to do it would be by adding some dynamic css to the exhibition plugin you use for that page -- save the plugin with some other name, so that it doesn't affect other pages using the same plugin but without the same effect
add this to the plugin, or just build one exclusively for this if you're not going to have any exhibition on that page. For example, like this:
at the beginning of the file, you may need to define defaults from general libraries (not sure this is strictly necessary for this, but it doesn't hurt):
$exhibit['dyn_css'] = dynamicCSS();
and the you can define your function for dynamic css, somewhere near the end of the plugin:
function dynamicCSS()
{
return "#menu { background-color: #A0E3F9; }
#menu ul li.section-title { color: #330066; font-size: 1.2em; } ";
}
Check a few of the plugins to see how they are written, for example exhibit.over_and_over.php. There are also variations that would also work well for what you want to do, for example: exhibit.horizontal.php
