Remove Underline from vb4

I'm wondering how vBSEO did this,

In postbit, how do you remove the underline from the links ?

I'm not exactly sure where it is, but basically you need to find the "a" super elements
a, a:hover, a:link, a:visted , etc and add
text-decorartion: none;

to the css rule

Added to the locations described for postbit.css in CSS templates, but doesn't seem to have any effect.
