Ok I'll try to do a brief summary The js engine is implemented in mozilla/js/src The newsgroup for it is netscape.public.mozilla.jseng. The documentation is at mozilla.org/js . You are not likely to get answers to your questions about CSS parser and HTML parser etc in this newsgroup. You will have better luck in netscape.public.mozilla.layout or netscape.public.mozilla.style. This newsgroup is about the documentation project, not asking about the code. NGLayout is the official name of the rendering engine, though nobody uses that name anymore. We use the name "Gecko" as a general term, though it doesn't really mean anything either. Basically the "rendering engine" is the HTML Parser + the layout engine + the DOM engine + the Style System. I think you will find http://www.mozilla.org/newlayout/doc/ to be interesting for your purposes. I can answer more precise questions about the DOM if you wish, but that's about it as far as I'm concerned. -Fabian.
