This page describes MediaGoblin's appearance and style. If you're looking to contribute to its design, this is good reading material.
MediaGoblin's default.... FIXME.
Besides the regular theme, we've created a lighter version for use on the wiki, documentation and other places that might require reading longer pieces of text. It is meant to increase readability through the use of a light background and higher contrast.
