Learn something new everday! I just added the following to the css for this site:
a {
outline: none;
}
Which will remove that little dotted line you get when you click on a linked image. I just learned that from Deziner Folio.
I got to that site because I recently installed the Sphere plugin for WordPress – (which I found out from reading Matt's blog) and Deziner Folio was one of the links that popped up from one of my css-related posts.
Incidentally, poking around there I also found a bunch of pre-made for-photoshop gradients and cool "badges" (starbursts, etc.) he was offering up free for the taking. As well as a really neat way to center a single div in the middle of the page using CSS.
