Not.

If on different domains, then only using JS is not . (Same-origin policy or Rule> domain restrictions)

The restriction of “ one source ” prohibits windows and frames from different sources from invoking each other’s methods and reading data from each other.

At the same time "from one source" means "the protocol, domain and port match ".

If on the same domain, then the usual JS like this:

 var cssLink = document.createElement("link") cssLink.href = "style.css"; cssLink.rel = "stylesheet"; cssLink.type = "text/css"; frames['nameOfElementIframe'].document.body.appendChild(cssLink);
