This video provides an excellent foundation for responsive design.

Dude love your tutorials on php...thanks for that, i don't think anyone explains stuff so well.

Great videos! I wish there was a set of tutorials included for Photoshop CS6 like the Dreamweaver CS6 tutorials that were very enlightening.
The only thing I didn't like was that it wasn't clear enough as to what ORDER to watch the videos in. They should have simply been put in the right order from the moment I went to download them. Also, referring to the proposed order of watching:
1. Web Design 1 - 225min
2. Dreamweaver CS3 + CS4 - 475min
3. CSS Layouts - 89min
4. CSS Lists - 85min
5. Photoshop for the Web - 300min
6. HTML Forms - 45min
7. Horizontal lists with CSS sprites - 24min
8. Beginners Javascript - 300min
9. Beginners PHP - 146min
10. Wordpress Install - 62min
