[SOLVED] Why isn't background color of menu bar showing?

Page: http://www.todddawsondesign.com/test/matia/

Code in insert CSS: div#menu1 { background: #384D3E; border: 1px solid #384D3E;}

ATA 3.7.9

I've gotten it to show other times, using the same code. I had some code I commented out above it, moved that code below it, and it worked. Now it's not working and I don't know why.
