hey nicolai,
i'm a little unsure what you mean by 'a site already hosted' but i assume you mean like a cafepress store. To use dreamweaver pages in a cafepress type site you need to just cut the code you want to use and paste it into the appropriate section of the page code. For example in my cafepress store, i took my header code and pasted it into the section for 'header ' in the customization page at cafepress. I guess what i mean is don't expect that you can make an entire page in dreamweaver then simply cut and paste the entire thing into a cafepress type site, because that will definetly not work. Actually, in cafepress you can make your homepage be however you want, but to display your products you will need to just add snippets of code. You need to fit your code around the code that cafepress, or spreadshirt or whatever adds to display items. It can take a bit of trial and error and fiddling around to get things to look exactly how you want them. To use style sheets, you can just make the css file and attach to your page in the head section of your page, or just define the styles in the head section if you dont want to use an external css. If you are using cafepress, i suggest you go to the forum there and get some more ghelp, theres some tutorials and stuff that some very helpful people have put together. I hope that helps a little. Thanks for your thoughts on my site, i like to think a little bit of me comes out in the site, my best attributes are that i'm simple, clean and sometimes friendly
All the best, Andrew
