[Plugin: Section Widget] Tab padding

Great plug-in, I love the simplicity of it all. One catch I’m running into is the tab padding. I have to admit I’m not the greatest with CSS. I checked out the themeroller (beautifully easy), but it doesn’t allow padding modification. I tried copied the based theme and started editing, but I can’t seem to get the padding to shrink around the text in the tabs. I thought it would be in ui.tabs.css, but changing the padding values in this don’t seem to change the style.

The reason I’m doing this is because I’d like to use narrower tabs as my widget space is limited.
