Way to edit style of another webpage within iframe, even superficially?
Is there any way at all to edit the way a page looks within an iframe? I want to change the color of specific links on, say, a google search within an iframe. 

Also, why doesn't the code below work in javascript console when google.com is loaded normally?

    document.body.getElementsByTagName("a")[0].style.color='red';
