Pretty Validation Pages

The validators at w3.org have been given a face lift. They are much prettier now than they were the last time I checked my pages. I use the Markup Validation Service and the CSS Validation Service very frequently. These tools are a great way to validate your HTML/XHTML markup and CSS. Incidentally the css validator can be downloaded for use on your own system.

For info about downloading see ...

I didn't see anything on a download for the markup validator but there are links to source code and lots of other documentation.
