be valid, or die learning This is a website that helps you check the markup and style validity of web pages. It does this by submiting the urls that you want to check to the W3C Markup and the W3C CSS Validators.

These validators send back validations resulats in SOAP format, which this website internaly consumes in order to produce the result you're seeing.

What's that β on your logo?

This means that this service is still in beta stage of developpement. We're sorry about that. But just as Paul Graham would say: It's more important to get it up than to get it right. :)

What does it use?

This website proudly uses some nice tools/technologies like: python, web.py, xml, xslt & xpath, javascript/jquery, yahoo pipes and mysql.

Be informed.

This is just the beginning, and there's lots of updates and new features to come. There's articles and very intersting blog posts about what gather us here: Web developpement and web evolution.
