html - How can I scale the content of an iframe?

Question

How can I scale the content of an iframe (in my example it is an HTML page, and is not a popup) in a page of my web site?

For example, I want to display the content that appears in the iframe at 80% of the original size.

Kip's solution should work on Opera and Safari if you change the CSS to:

<style>
    #wrap { width: 600px; height: 390px; padding: 0; overflow: hidden; }
    #frame { width: 800px; height: 520px; border: 1px solid black; }
    #frame {
        -ms-zoom: 0.75;
        -moz-transform: scale(0.75);
        -moz-transform-origin: 0 0;
        -o-transform: scale(0.75);
        -o-transform-origin: 0 0;
        -webkit-transform: scale(0.75);
        -webkit-transform-origin: 0 0;
    }
</style>

You might also want to specify overflow: hidden on #frame to prevent scrollbars.
