My blog is red and yellow!!

My blog had a facelift. I hope you enjoy it. I also hope you can tell me how to get that scandelous strip of blue off of my beautiful red, yellow, and brown blog. :(

I'd also like to know how to make my blog wider... I know for my screen it is merely half the width of the screen. Odd. Silly template. I wish I knew more html. Sibling?? Help!!
