I have a pretty basic site that has two levels of navigation... primary links and secondary links under each primary link. I need to display specific css based on the primary link and/or any of its children (secondary) links that are clicked on. I have the snippet for displaying different css files figured out. Now, I need to know what arguement I need to pass to my if statements in order to display the correct css. I'd like to assign a category to each primary and secondary link but don't want the category name displayed anywhere in my content. I just want to use it as an arguement to pass to my if statments for importing specific css files.
So, how would I go about grabbing the category arguement if I don't want the category displayed anywhere on the page??
