GlyphGate contains a built-in HTML and CSS validator that will assist you in creating web pages that are syntactically correct. The validator will find things like missing end tags and illegal constructs in the pages processed. GlyphGate can be configured to enable the validator for all pages on the site, or only certain directories, etc. Optionally, and as a great help during page development, GlyphGate can be configured to visually indicate if a page contains syntax errors. Just follow the link below to see the validator tool in action.
