Well, for simple HTML and CSS, I like to use these validation tools:

   http://validator.w3.org/     and    http://jigsaw.w3.org/css-validator/

Granted these two won't even begin to deal with all the complexities of 
dynamic web
pages.  I'm somewhat surprised there aren't more complex (and probably 
costly) page
validators available that will do more comprehensive checks.
