I am using jquery UI tabs and I need to majorly change the styling on it. I need to rempve the background image, the borders, almost everything. I need it to look minimal, and not like it's self contained.

What's the best way to do this? I need to use the default UI styling for the calendar widget however, which is on the same page. I've done a lot of research and everyone seems to point to the theme-roller. However, i do not just want to change the colors and border radii. I need to delete crap. theme-roller seems to be just change things like colors (not really useful for the real world). How do I adapt the css for the tabs without changing the styles of the other UI widgets on the same page (I want the calendar to stay as it is)?

Is it even worth using jquery UI for my tabs?
