SuperEmbed.js

Live demo now available here.

SuperEmbed.js detects embedded videos from YouTube, Vimeo, Vine, VideoPress, DailyMotion, and more on webpages and makes them responsive. Essentially, this means they stretch to fill their container while still maintaining the content's original aspect ratio.

I created SuperEmbed to fix all my issues with existing solutions, including (but not limited to) unnecessary reliance on other libraries, bloated code, and poor fallback support.

Features

• Works without external libraries like JQuery
• Responsive videos maintain their original aspect ratio
• Responsive layout can be forced or blocked with classes applied to the embed code
• Extremely tiny, the minified version is only 3 KB

Supported Services

SuperEmbed can automatically detect and resize embedded content from these sites:

• YouTube
• Vimeo
• SoundCloud
• Kickstarter
• CollegeHumor
• Hulu
• Flickr
• Vine
• VideoPress
• DailyMotion
• Twitch.tv
• Vid.me
• Facebook
• Gfycat
• LiveLeak
• MSDN Channel 9
• MySpace
• Archive.org

Browser support

IE9 compatibility requires classList.js, included in the 'extras' folder, to be loaded before SuperEmbed.js. This is not needed for IE10 and up.

How to use

You can put the SuperEmbed script wherever you want on the page:

<script src="superembed.min.js"></script> 

Then it will automatically resize any supported embedded videos. That's it.

Note: If you already use JQuery, and you load SuperEmbed sometime after it, SuperEmbed will use JQuery to detect when the page is loaded and the window is resized (instead of DOM JavaScript).

Advanced features

If you want to make an embedded video (or really any element) responsive, but it's not automatically detected by SuperEmbed, you can add the .superembed-force class to it like this:

<iframe src="http://www.example.com/video" class="superembed-force"></iframe> 

You can also tell SuperEmbed to not resize a specific embed by adding the .superembed-ignore class, like this:

<iframe src="http://www.example.com/video" class="superembed-ignore"></iframe> 

And finally, you can force a 1:1 aspect ratio by adding the .superembed-square class, like this:

<iframe src="http://www.example.com/video" class="superembed-square"></iframe>
