Clear float on footer
Changed some formatting

I removed the center on the heading in HTML and moved it to the CSS.  I
then added some CSS formatting and put is a CSS color scheme.  I don't
fully know CSS how to use the colors I added, and it is kind of dark and
monochrome.  But I put it in to show what I know about css formatting.
