Also, something that I've found is that if you go wrong somewhere instead of mindlessly searching for the error (assuming there are multiple or you don't know the error's location) just start from the beginning and go down seeing that if this works. If you see a break and something disconnects, in all probability that's where the error is. It's all logic.

Coding is all in the details, which is why you need to “celebrate small victories,” as one of our programming professors put it. It takes practice to make each element work on its own, as well as constant testing to ensure each line of code will work with all the rest—without errors. If you don’t do seemingly minor things right like closing a HTML tag, you’d be stuck debugging a simple syntax error rather than writing more impressive and complex code.
EdX is another leading online-learning platform that is open source instead of for-profit.
