You can edit the CSS file in any text editing software you want. If you are looking to actually 'see' the results however, it isn't going to help you. The only way to do that is to save it up to your skin1 folder and see how it looks live. Same goes for the templates. You can edit them with Dreamweaver to see the table cells, but there will be no content to preview, as it is all populated using smarty tags and database queries.
