WYS-isn't WYG in Dreamweaver CS5

Good morning all,

I've been putting together a new site and am struggling with differences between what's in Dreamweaver and what shows up in browsers.

The site will end up as commercial but is currently at the testing stage - you can see the first bits at dedint.co.uk

In Dreamweaver, what I get on the screen and what appears in the browser are markedly different. For example, the text isn't properly aligned, is the wrong colour and the wrong size. The link buttons (the tombstones) aren't centered, etc.

The frustrating thing is that most of the commands make no difference. For example, the text alignment = left in the CS5 window - but the text doesn't shift.

Please let me know if you've an idea what the problem might be. If you wish to see anything more, such as code, please feel free to ask.

All the best,
