Theme development

Ive added this to several themes and its gone over well. So far, the only place Ive seen the dl/dt/dd lists is in admin pages and ones like "create content". The following css spaces the descriptions from the text a little more nicely and makes the links bigger than the description text. I found it to be a very functional little ui enhancement:

dl {
	margin: 0.5em 0 1em 1.5em;
}
dl dt {
	font-size: 1.2em;
}
dl dd {
	margin: .5em 0 .5em 1.5em;
}

Hi! I have the chameleon theme right now, and I need some help with a couple things:

I was wondering whether there is any way (perhaps a module) which enables you to edit style.css for a theme from within a Drupal installation itself, perhaps by having the contents of that file in a node? I would like to give my designer control over the stylesheet without him having to upload by ftp.

I have created the new content type "Real Estate", and added 2-3 fields using the CCK module.
I have to change the CCS from dupal's core theme to my own derived css(am not a designer).

I have to display the fields, Title(from content type) and Price(from CCK module) in same line.
Somewhere i have to shorten the length of textbox, whereas somewhere i have to keep it as it is.

AM not able to figure it out, which "div" they had used, and which div i have to copy and reuse in my css?

Please help...

I am working on customizing the VoteBob...I want to change the Primary Links to white, but when I try, it changes all of my links to white (and I've got a white background). Can anyone tell me how to fix this?

Here's parts of my css file that (I think) are relevant:

a { color: #3B5477; }
a:hover { color: #000000; }
a:visited { color: #3B5477; }

#primary-links {
text-align: center;

}

Again, with apologies on my lack of Drupal-ology as I'm a recent convert from WordPress...

Help!
