Tutorials and Tips at W3C: CSS, HTML, Accessibility, SVG, and More
Tutorials @ W3C is a listing of links to tutorials written by the developers of the technologies themselves, when possible. You’ll find tutorials on HTML, CSS, XML Schema, SOAP 1.2, SVG, P3P, VoiceXML 2.0, Semantic Web, and Accessibility. W3C has also provided links to tutorials and resources elsewhere on these and other W3C technologies.
Quality Tips for Webmasters is a new and growing area with helpful tips for web designers and developers about the importance of <title> elements, link text, using h1 for titles, and more. It’s a small section right now, but it’s off to a good start.
More: A CSS 3-column Layout Tutorial
Looking around the W3C site, I also found Tableless layout HOWTO, a CSS tutorial with instructions and markup for creating a 3-column layout with CSS, by W3C’s Dominique Hazaël-Massieux. This tutorial also provides information about HTML tables vs. CSS for layouts. Also included are links to more CSS layout tutorials and W3C specifications.
