Solution 1:

Basically, in an iframe you load a different website or webpage.

The scripts, elements and CSS have to be controlled from within that page.

Solution 2:

var iframe = top.frames[name].document;
var css = '' +
           '<style type="text/css">' +
           'body{margin:0;padding:0;postiton:absolute}' +
           '</style>';
iframe.open();
iframe.write(css);
iframe.close();

You have to do that in HTML not in the css file. But the inner style of the object in the iframe must be handled in the css of the website/server from where the page loads
