There are two approaches. I'm in the minority club on this one (at least on this site) so sometimes I just keep quiet, but for what its worth...
If you want to use the "What You See Is What You Get" approach you use something like Dreamweaver or the others. You drag and drop or whatever and the program writes the code.
If you get familiar with html and css and like working directly with the code you can just use a text type editor (even Notepad) and look at your work on your browser as you go along. This approach gives you great control and you can adjust anything you want easily (if you know the code).
I use NoteTab Pro for my html and Top Style Lite for my css and keep both open at the same time (along with the browser). Both of these work great because they fill in most of the code for you from a menu on the side. For a simple example, when I select a section of text and click "paragraph block" on the side it puts the code <p> and </p> around the selection. If you decide to go the code route I highly recommend these two programs. (NoteTab does the css, too, but I like using both together better.)
