week 4 lecture (crazy using the marquee tag) :P

This week in tutorial, I continued editing my page. We learnt how to add footer, header and creating new tags. It is fun because I can make the texts move by using marquee tag and my page looks great.

The things that I don't really get is to make a side bar and somehow the color that I've chosen in CSS file doesn't match up with the one in HTML. I don't know why. :(

Please someone tell me what i did wrong so I can fix it because at the moment the background color would not appear. :(

thx!
