Well i found a really good coding site that will help you code, do some coding for you, teach you alot of stuff, well here it is!

Hope you like!
w3schools gets my vote, hands down.
W3 Schools is way better I learned from my cousin, Sams Guide to Learn HTML in 24 hours, and W3 Schools, also a little help from Faltzer and Coolmaster
Lissa Explains is best if you're a complete beginner since w3 schools was way more confusing for me way back when I had zero HTML knowledge. But yeah, if you want to learn more advanced stuff, W3 schools is definitely the way to go.
I know w3chools is better but It's a bit complicated if you don't know any HTML, Lissa explains is for newbies to HTML and I'd say echoecho is about inbetween.
I found a new one too,

W3 schools gets my vote. Taught me lots of good PHP stuff in less than a day.
I've never liked W3Schools that much. Lissa for me! ;D That's totally where I learned, and the first ever PJN was a result of it.
