[thelist] SSI if/include/css

I'm wanting to load certain fragment files based on the stylesheet that is
loaded... I know you can set variables, and then <!--#if expr="(insert
variable here)=">  blah blah blah and on and on.. 

but the Variables seem limited to date, time, browser, screen res, and a
few others...   Is it possible for me to set a variable name to the style
sheet that's loaded?  I have no idea if i'm making sense? or if there
might be a better way to go about it.

Thanks,
Jeana
