Make WordPress default video embeds responsive

Unfortunately WordPress does not add a div around embed codes by default, so this is the first thing we need to do to get it to work.

Add this to your theme’s functions.php:

/*  Add responsive container to embeds
/* ------------------------------------ */	
function alx_embed_html( $html ) {
	return '<div class="video-container">' . $html . '</div>';

add_filter( 'embed_oembed_html', 'alx_embed_html', 10, 3 );
add_filter( 'video_embed_html', 'alx_embed_html' ); // Jetpack

And next up, we need to add the CSS that makes it responsive to our style.css:

.video-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; }
.video-container iframe, .video-container object, .video-container embed, .video-container video { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

And that’s it! You now make iframe, object, embed and video (html5) elements responsive. The responsive CSS will always show videos in 16:9 aspect ratio, which is HD.

This code will also work with Jetpack embeds.

    Hello, I’m trying to use this but it doesn’t automatically add the div around the iframe code. Also tried with your theme and same result.

    Do I need to add the iframe to the post in a special way? I’m doing it right now changing the post editor to text mode and pasting the youtube iframe code.
