Browser Quirks

I just found this great site put together by a guy in Amsterdam, named Peter-Paul Koch. The site is basically a study on the quirks and differences between browsers.

It contains more than 150 pages with CSS and JavaScript tips and tricks, and is one of the best sources on the WWW for studying and defeating browser incompatibilities.

The site's very well done, and has some great information about how each of the browsers handles different CSS styles and javascript. It even has some in depth "experiements", showing you the effects of various scripts and styles in each browser.

If you're a web developer, I'd recommend you keep this site handy.
