Site Wide HTML Markup Validator: W3Clove
The official W3C validator does not yet provide a way to submit several URLs at once. So, if you want to check your whole website, you need to submit each of your URLs individually, which is a slow process. W3Clove provide a simpler, faster way to submit several pages at once.
W3Clove is a site-wide HTML markup validator. It allows you to check the validity of the markup of several pages from your website, and gives you a summary of the most common errors and warnings, with a single click.
it’s really nice
