If your goal is to build a web application, I'd suggest railstutorial.org. It basically picks up from your HTML skills and shows you how most of the things are done these days. A great alternative would be treehouse, which helps you to answer this question at the first screen (what do you want to learn? web design, development or mobile development?). Go through the tutorials, build some stuff and use stackoverflow when stuck.
