HTML & CSS validator

Hello,

With these 2 websites below from the W3C, you can validate your HTML & CSS. It's free and you can correct any errors with ease! You can do this in 3 different ways: validate by URI, uploading your .html/.css file or by direct input.

HTML: http://validator.w3.org/

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

Regards,

Andrew

I'm a big fan of using HTML Lint for making sure that I have clean html.

Thx James!
