I haven\'t seen any docs saying jQuery can change any CSS definition such as changing
td { padding: 0.2em 1.2em }
to
td {
Nope, it just doesn't work this way...not sure any better way to explain it than that :)
jQuery was designed to work on elements...if you're doing this for testing, Firebug of the Chrome console are options though.
Something you could do, is have a server-side generated stylesheet, for example how ThemeRoller does it, and jQuery (or vanilla JS) dynamically adds that into your header, something like:
If it was the last link, it'd override the previously defined style...in fact this is exactly how ThemeRoller works.
