I'm sure much of this has already been said, I'm just stating my opinion:
First off, videos are way overkill. Once you grasp the concept, HTML will come second nature to you. Spend some time reading through the HTML tutorial on w3schools.org
. I taught myself HTML in a little under a day just by reading W3Schools' tutorials and you can to.
Regarding an editor, IMHO you shouldn't touch anything with advanced features such as Dreamweaver, Coda, or even Notepad+. The best way to start is with a simple monospaced font text file editor (Notepad is the obvious choice). Too many people jump right in and start using editors that do half the work for them (ending tags, listing tag attributes, CSS properties) and they aren't really learning the fundamentals. By using Notepad you have to know what you're doing and it forces you to memorize tags and attributes whereas Notepad+ will provide hints that are useful to experts like myself who are extremely lazy typers (or want to save time), but can negatively affect someone trying to learn the language. I cannot stress enough how using Notepad to being with is important!
Well that's my advice; take it or leave it, but whatever you do, have fun with your programming endeavors.
