Embedding a Flash Header with a css template?

Hello everyone!

I am very new to css and trying to learn as much as possible.

My school needs a website, so I got a free template that uses css. I'd like to insert a flash header I created, but when I try to do it directly into the html code, it messages everything up. I know you cannot embed the flash into the css, so how can I get around this problem?

Any help you could offer this newbie would be greatly appreciated.

Thank you.

You need to be a little clearer about what you mean by "messed up" and post some code that you have tried.

Since I don't know a lot about CSS please bear with me.
I have a template and I decided to put the flash movie in place of the header image. When I did that, it messed the template up because of the CSS.

I know you can't add the .swf code into the CSS. So in my case, what can I do to insert the movie in place of an image that came with the template and not have the entire template shifted. Hope this makes more sense.
