Welcome to the W3C HTML Validation Service; a free service that checks documents like HTML and XHTML for conformance to W3C Recommendations and other standards.

Why does this page render badly?

Most likely this is due to a bug in your browser's support for the W3C Cascading Style Sheets Recommendation.
