HTML code

The only time i have used the actual html code is to change my background on myspace. I know there is a lot more u can do with myspace but never took the time to figure it all out. To change your background you just copy a html code from the Internet and paste it into your about me box and magically a new background appears. I really have know idea how the html code works but always wanted to learn. So I am mildly excited about building a actual web page.
