I will be the first to admit that I rarely think about validating my pages while I work. Okay, sometimes I don’t validate at all. I know I should, but I can usually come up with a good excuse for not doing it – an elephant ate my homework still works on occasion. ;-) And as a Dreamweaver user, validating against the W3C validator was always that “extra step” that I didn’t feel like taking. But with Dreamweaver CS5.5, there really is no excuse anymore – it’s now built directly into the app!
When you’re ready to validate your page, simply click the W3C Validator button and choose whether you want the local page on your computer validated or a page on a server.
