Question: What's a good book, or a good way to learn HTML, XHTML, and CSS? I recently graduated from school and I only know Java, and C++.

I would like to learn some web development so I am looking for some good books and resources.

Answer: 
If you are interested in online resources, The [SitePoint Reference](http://reference.sitepoint.com/) seems good. It covers HTML, CSS, and JavaScript. The information seems clear, and there is the capability to add user notes as well.

If you prefer printed material, I started out with HTML for Dummies - despite the common opinion on For Dummies books, they are actually useful for picking up a new subject. I keep handy the HTML/XHTML Definitive Guide and the CSS Definitive Guide - both from O'Reilly. Those two are good for references.

For JavaScript, I recommend Simply JavaScript from SitePoint, and Dom Scripting from Friends of Ed.
I'm working through Head First HTML with CSS & XHTML. I have found it to be quite useful in staring me off with these technologies.
