Now there's no excuse to not develop sites using open standards - check out Opera's free online curriculum...
Chris at Opera sent this:
I'm contacting you because the first release of the Opera Web Standards Curriculum is now available at http://www.opera.com/wsc.
This is Opera's tutorial course, aimed at improving the level of education in web standards worldwide, and increasing the rate of standards adoption on the Web. Once finished, it will provide a complete coverage of web design theory, HTML and CSS, and a solid grounding in JavaScript basics. Even better, it's completely free to use and distribute - released under a creative commons license.
We think it will be useful to anyone who wants to learn or teach client-side web design/development "the right way", including students and teachers at schools or universities, trainers and employees inside companies, etc. It already has support from several universities and large companies, including Yahoo!
I'd like you to pass this on to anyone you think might find it useful, and blog about it, if you like it. Feel free also to give me feedback - suggestions for improvements etc.
There are over 50 proposed articles, and 23 are currently published.
All the best,
Chris Mills
