The metasite at University of Colorado is a good starting place. There are many options for searching specific topics. The simplest way to conduct a keyword search is to select Net Search from Netscape menu. For a search using subject trees, try Net Directory. Metacrawler searches eight of the search engines at once.
Page is a good place to start for a variety of web-building tools.
I highly recommend this site for HTML reference . This is an almost complete HTML reference page. A beginner's guide on how to write HTML documents. Or try this HTML Crash Course. SpiderSchool gives an artist's perspective of the web and good basic design information and resources.
