New Post: Editing the Styleseet.css and removing borders isnt working for me...

ok, normally you'd just use this for the list items - Put this into the stylesheetoverride.css template so that you don't have to mess with the stylesheet.css template.

.ListItem{

background: none;
border: none;
box-shadow: none;

}

And this will get rid of the boxes around the gallery thumbs:

.Detail .GalleryInner {

background: none;
border: none;
box-shadow: none;

}

However, there's also a stylesheet named foundation.css that for some reason is applying those very same styles to all tables, so you'll need to clear that. That is what is causing you grief.
