BlueGriffon is an intuitive application that provides Web authors (beginners or more advanced) with a simple User Interface allowing to create attractive Web sites without requiring extensive technical knowledge about Web Standards.

Because Gecko lives inside BlueGriffon, the document you edit will look exactly the same in Firefox 4. Advanced users can always use the Source View to hard-code their page.
