How to make an Iframe border disapear?

I tried in the past to totally remove the iframe border in FF but it never worked. Now as we all know there are a lot of sponsors out there who supply geobanners etc. and they dont have that border around it.

Is there stylesheet command for it that gives the border a specific colour?!?

Anyone knows how they do it?

style="border:1px solid #000000"

Change 000000 to the colour you want

Thanks guys, train is running again

So you want your Iframe without borders?

you have to set the following attribute:
frameborder="0"

That?s it.
