Learning Basic HTML

This stuff is hard!!! I find learning how to work HTML is very difficult to grasp. I have never been a computer junkie, and trying to understand basic HTML flies right over my head. Now, don't get be wrong I can do HTML, but I am not grasping the idea as fast as I would like to. The whole outcome of HTML is very cool. I would love to be good at it. But for me figuring out what tag to do when and where is difficult.
