Here is a program i use to code my css:-
http://www.bradsoft.com/topstyle/
Download the Free version and have a look, thats what i use and it does everything i need.
One thing i do have trouble with is getting something possitioned at the bottom of a page, such as a footer or an image.
At my site
www.wingsofwar.org.uk (still under testing & construction so most links dont work)
I wanted to postion an image at the very bottom right of the page. I couldn't get it there for love-nor-money ! So i went back to putting a table on the page to get it there, then using css for the rest of it (in the main anyway).
Tables are a habit thats hard to quit ! lol
What do you guys use to get something at the bottom ?
Cheers
