BlueGriffon is a new WYSIWYG content editor for the World Wide Web. Powered by Gecko, the rendering engine of Firefox 4, it's a modern and robust solution to edit Web pages in conformance to the latest Web Standards.
It's free to download (current stable version is 0.9) and is available on Windows, Mac OS X and Linux.
BlueGriffon is available in English (en-US), French (fr-FR), Portuguese (pt-PT) and Simplified Chinese (zh-CN).
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.
