Styles show in Dreamweaver but not IE7

I'm building a website with Dreamweaver 8 Pro. I have attached a css style sheet in the head of the page. There are many styles which I have set, such as borders, which display exactly the way they should in Dreamweaver, but when I test it in IE7, it doesn't look right.

EX:
I have the css code for borders:


In Dreamweaver, the borders display exactly the way I want them to. When I view the page in IE7, however, there are no borders at all.

Any ideas on how to fix this?

Thanks in advance,

I think I need for code. Maybe just the page you are trying to display. With the CSS sometimes it isn't in the CSS but maybe where you apply it.

That .body class is being applied to a table. What else do you need to see to help?

Thanks again,

Well I think to start if you are using CSS that don't use tables. You can do everything with CSS and easier. I think that may be the problem table kind of comes with a border. So you are appling a border on top of a border. Don't use the CSS if youare using tables just use the borders it comes with. Or get rid of the table and use CSS.

Thanks for the tip.
