Although most of the team does not spell favourite like this, I originally hail from England and occasionally enjoy antagonizing my colleagues with the British spelling. Here are a few sites that we believe are valuable to web developers.
Dynamic Drive has lots of useful widgets to add to web pages from menus to games.
Web Reference has lots of resources for web authoring. Including a specific DHTML lab http://webreference.com/dhtml/
WebFX has plenty of samples including their constantly evolving menus and the excellent behavior for enabling PNG transparency in IE that I’ve discussed before.
I know many are concerned about the level of CSS support in Internet Explorer and we certainly hope to address some of these issues, in the meantime though there is Dean Edwards excellent work that helps here.
There are lots of great resources out there. Tell us the sites you find most useful for web development in the comments for this blog.
