Yep, that did it! TY x 1,000
Found this and changed the color hex code to #660099.
div#menu1 {
background: #eee;
}
It's interesting that...
1) The css code in the insert window for div#menu1 does not show in Firebug
and...
2) That I had tried assigning a different background color to div#menu1 at the top of the css insert window in ATO... but I did not realize that my new css definition was being overruled by this other css definition that is just changed because it was appearing further down in the insert window!
Thanks,
Simeon
