Currently, the wiki I'm working on has the blank, default infoboxes, seen in this image.



However I've noticed some advanced versions and designs on other wikia, notably [this really fancy one.]

I'd like to know how to edit the design of the infobox to get similar effects, such as a gradient background and those custom-designed corners.

Also, what is an 'Ambox'? I've seen this all over the CSS editor but I can't figure out what it is.
