Web coding goals/challengs?

Question

So with my skill level (check my codes), what are some interesting challenges I can do to improve my coding skills? I want to learn, but I'm running out of ideas.

Answer 1

I like playing here (entered 31 challenges so far.) Even if you don't try for the shortest code, the challeges are fun. You don't need an account to read them (only to post an answer.)

How about I give you a challenge?..
Build a real website from Heroku hosting.
