Topic: Dashed iframe borders?

I'm working on a new site, here it is:
http://www.onefreehost.com/ryanvh22/blockhead/main.html
I want to make the iframe with the marquee in it (on the left of the page) have a dashed black border. I know how to do this in my css

iframe { border: 1px #000000 dashed;}

but I have two iframes in the page, and I don't want both to have borders.

Is there a way to make only one iframe have a dashed black border?

create a class in your stylesheet -

.dashed-border {
border:#000 1px dashed;
}

in your HTML, call the class for the iframe (or any other element) for which you want the dashed border -

<iframe class="dashed-border">

Or, if you have several specific styles you want for that particular iframe, setup an id -

#my-iframe {
styles...
}

and call it in your HTML -

<iframe id="my-iframe">

Awesome, thanks man
