iframe {
  max-width: 100%;
}

responsive-iframes.html

<!-- All you need is a defined width & height -->
<iframe frameborder="0" height="426" src="http://www.slideshare.net/slideshow/embed_code/9812085?rel=0" width="510"></iframe>

responsive-iframes.js

function adjustIframes()
{
  $('iframe').each(function(){
    var
    $this       = $(this),
    proportion  = $this.data( 'proportion' ),
    w           = $this.attr('width'),
    actual_w    = $this.width();
    
    if ( ! proportion )
    {
        proportion = $this.attr('height') / w;
        $this.data( 'proportion', proportion );
    }
  
    if ( actual_w != w )
    {
        $this.css( 'height', Math.round( actual_w * proportion ) + 'px' );
    }
  });
}
$(window).on('resize load',adjustIframes);

Works well. We use it at NPR. If you have any problems file an issue. Always trying to make sure we keep up cross browser compatibility.

Can someone help clean this up for me? I tried embedding this into a WP javascript editor for use in a WP site, it doesn't work. I cleaned up the spacing syntax as they suggested, but I still get this:

function adjustIframes()
{
$('iframe').each(function () {
var
$this = $(this),
proportion = $this.data('proportion'),
w = $this.attr('width'),
actual_w = $this.width();

        if (!proportion)
            {
                proportion = $this.attr('height') / w;
                $this.data('proportion', proportion);
            }

        if (actual_w != w)
            {
                $this.css('height', Math.round(actual_w * proportion) + 'px');
            }
    });
}

$(window).on('resize load', adjustIframes);

!!!!!!!!!!!!!!!!!!!!Sorry for how this window is formatting the code!!!!!!!!!!!!!!!!!!!!!!!!

Thank you!

Works great! Thank you very much!

Great job, thx!

Very cool! Thanks!

Nice work, Aaron. Works like a charm.

For a more complete solution that keeps the iframe size to the content when the content changes, or the browser resizes. Check out this library.

This is using Jquery? how about not using Jquery? :)

Great! It just does the job 😃
