Hello,
I'm slowly learning HTML5 and CSS3. While trying to convert one page over, I'm running into problems and I'm not sure how to correctly solve them.

Here is the HTML4 page and corresponding stylesheet: http://www.flimpact.org/html4.html
http://www.flimpact.org/html4css.css

and

Here is the HTML5 page and corresponding stylesheet: http://www.flimpact.org/html4.html
http://www.flimpact.org/html5css.css

To start off with, I'm not sure why the borders on the top two menu bars aren't working or why the brown background color isn't displaying in the div next to the photo.

And of course the display differences in the different browsers are further confusing me. I think I could figure out how to eventually get the HTML5 page to look like the HTML4 page, but I would really like to do it correctly and to understand why certain things aren't working.

Any help is greatly appreciated.
Deborah
