If you are looking for tutorials online, as people have said before, w3schools is a very good step-by-step tutorial. One thing you need to do is make sure to read EVERYTHING. I made that mistake when I first started learning HTML. Otherwise
http://tizag.com is another very well made step-by-step tutorial on all kinds of web designs and also has some eaxample scripts where you can try to write some html code without creating a file on your site.
Otherwise if you arent looking for an online source and wish to read it at a local bookstore etc. I suggest O'reily books. They are very well written and give very good examples.
I remember how hard it was to start learning html at first, and I got very frusturated, but if you stick with it and keep trying, youll eventually get it.
