So using Chrome to "inspect element", I noticed that my added tweaks do not overwrite those found in tabber.css (Tabber's base css styles). Not sure what "!important" means, exactly, but using that tag overwrites tabber.css' and removed the padding.

Stranger still is that this default "3px" padding doesn't seem to affect other wikis :/ Anyways, Tabber tabs now look better. As for replacing HTML declarations with CSS, that's a different story and something I'll leave for someone else :P
