Ok, here's where a lot of people will appear to say I'm wrong.
Use
http://www.w3schools.com/ They do have errors and are slow to correct them, but you can't beat them for a step by step method to learning. Another site I highly recommend is
https://developer.mozilla.org/en-US/docs.
I do not use Dreamweaver. I did a long time ago, but not now. It is far too expensive. PSPAD
http://www.pspad.com/ is a free editor. I use TSW WebCoder
http://www.tswwebcoder.com/. It has it's flaws, but only costs $50.00.
Google
coding editors and take a look.
And Good Luck to you. We're always here when you need help.
