effect, only on roll over, and not by default?
In the default skin which comes with 3.0.7, i found no option in main CSS for this.

well, normally it would be easier just to do a rollover image in HTML. CSS just allows more versatility when it comes to placing images on a site via per pixel.

In the default skin which comes with 3.0.7, i found no option in main CSS for this.You will have to add some css.

In the main CSS panel, you will see the style rules for various elements. The first one is "Body." Along the bottom of the Body box, there are three little boxes labled "Normal Links CSS," "Visited Links CSS," and "Hover Links CSS." At the bottom of each of these boxes is a field labled "Text Decoration." This is what you have to change. Put "none" in the field for normal links and visited links; put "underline" in the field for hover links.

Go through each of the style definition boxes on that panel and do the same thing.
