Wow! Didn't even know this existed. I do a lot with CSS, and will caution anyone wanting to play with this to make sure you maintain good "habits" (i.e., make a backup before you begin). Things can really go south if you don't watch what you're doing. The CSS file in iSiloX is not a typical stylesheet, so be careful!
To really understand what the stylesheet settings impact, you'd have to see the native code and find the tags...but you can't see in a .pdb file like that, so it will take some trial and error to discover what does what (other than the obvious tags).
One interesting note is that there's a class in the sheet called "@media_speech"...what is that for? Indicates voice-based playback of some type, with both a male or female voice. Is anyone's PDA talking to them?
