Without actually seeing your webpage in questionable
situation, so I don't know what to say.
As in changing color using HTML code around Fireworks, I
don't think so. You need to use a HTML editing authoring app to
change the background color in pop menu. While Fireworks is a web
image or web graphic editing application. Although, it can create
pop-up menu, but it actually does not produce a HTML. It just loads
a pre-scripted html codes somewhere in Fireworks app. It is not
really a html editing app, just to clarify.
Do you have a HTML editing app? If so, what is it?
Additionally, do you know or understand how HTML works?
Furthermore, your question is actually related to HTML stuff and if
you use Dreamweaver, you could post the same question at
Dreamweaver General Discussion forum.
Here's my temporary site. I just want the background color
within the pop menu to change on the first listed item only. the
background is white all listed items, I would like the first item
to have a blue background with white text.
