This is my first post so go easy.

I just started learning web design about a month ago. I have already gone through a couple HTML/CSS books and completed the Javascript/JQuery lessons on Code Academy, so I know the basics. I tend to learn much better by looking at code and then modifying for my needs. I was thinking of using a framework in order to see how good HTML/CSS is written. Has anyone done this? Any recommendations for a framework? I was thinking Foundation.
