BlueGriffon is a new open source WYSIWYG cross-platform editor based on Gecko, the same rendering engine that's used in Firefox.
Because it's WYSIWYG, its easy to use and because its just been developed, it conforms fully with the latest W3C Standards including HTML 5, CSS 2.1 and large parts of CSS 3, CSS Mdia Queries, MathML, SVG etc. The fact that it uses the same rendering engine as Firefox means that its particularly good for designing websites for Firefox users.
The project you edit will look exactly the same in Firefox 4 as it does while you're working on it. If you're an advanced coder, you can switch to Source View mode to hard-code your page so there's something for beginners and experts in BlueGriffon.
BlueGriffon is very impressive although its still very much a work in progress. There's very little in the way of help documentation so using it is a case of trial and error. However, the WYSIWYG interface makes it easy enough to feel your way around. Although BlueGriffon is free to use, it can be extended with add-ons, although some of these aren't free and working out how to add them onto BlueGriffon is a bit tricky.
BlueGriffon is an very impressive up and coming free WYSIWYG website editor which may prove a very solid alternative to commercial options.
