Font

Typetester (http://www.typetester.org allows you to fiddle around with CSS font settings until you find the right one for your site. You can adjust the font’s family (websafe and not), size, leading, tracking, alignment, word space, underline, color, background color and font weight, with a live preview on the same page. Once you’re done, the page will spit you out a list of CSS properties that you can paste directly into your stylesheet.

Also, the site’s design packs 3 testers onto the same page, so you can lay your fonts out next to each other and see how they work together. You can also use this to test alternative fonts for dimensional compatibility. Nifty!
