I dislike reviews that don't tell you the verdict until the end. I won't do that. You'll get my verdict in the very beginning, every time.
Treehouse is an online technology school and it's amazing. Anytime someone asks me the best way to learn the basics of web development, I point them to Treehouse first. It's reliable, fun, incredibly high quality, and they're always adding new content.
What you can learn
With Treehouse, you can learn web development, web design, iOS programming, Android programming, and how to start a business. The "web development" category has the most content. You can learn HTML/CSS, JavaScript/jQuery, Ruby on Rails, PHP, and even Wordpress, all through tidy packages called Learning Adventures.
