You can style Tabbers (example), just not through inline styles as you probably mean. In order to style them you can use your MediaWiki:Wikia.css (or MediaWiki:Common.css). If you need different tabber styles you will need to put them all in specific classes, like:

And then put your styles in the CSS page. Of course, this is assuming you have admin access.
