Apply CSS to iframe

Question

I add iframe from external site to mine like this:

<iframe src="http://site.com/page/"&gt;&lt;/iframe&gt;

It has some own css and javascript files.

How can I add my own css styles to this iframe?

Answer 1

If the iframe source is not the same domain as your site, you can't add your own CSS to it due to same origin policy.

Answer 2

Are you trying to format the iframe border or its content? The latter isn't allowed for security reasons, the former can be archieved with a simple stylesheet (selector "iframe").
