Learning some HTML......sort of!

I know my brothers are laughing right now.  I did take a class in college on HTML and such but I did not listen or pay attention.  I am figuring out a few things.  I added those tabs all by myself.  Well, I used a great blog to get some answers.  I tried one other thing but he got over my head.  I tried teaching a little to my elementary students but that lesson plan went out the window!
