I hope this is the correct place to post this:
I am developing a web site for a e-commerce business I will be
running.  The site I'm setting up will be 50% store, 50% content.  I'm
not sure which shopping cart I'll be using yet (am looking at
os-commerce and miva) but the other part will be content.  I will be
writing reviews of products, articles on the industry, and someday may
have some blogging and forums and advertising.  I have to add that I
am not much into programming and I want a good web site but most of
all what is important to me is ease of use and a easy to update web
page.  I will be using Macromeda Studio 8 to develop it (dreamweaver
and flash)
Is CSS (Cascading Style Sheets) a technology I'll have to learn?  What
is it used for?
