An embed displays content from other websites like YouTube videos or Google Maps


When to Use

Responsive Aspect Ratio

Embeds use an instrinsic aspect ratio which allows them to resize responsively based on their expected aspect ratio and not by using a single specified width or height.

Only Load After Interaction

Including an iframe embed directly will automatically load all iframe contents on page load which can drastically reduce the responsiveness of a page.

Semantic's embed combats this by not loading iframe content until a user has interacted with your embed's placeholder content.

To give you an idea of how much file size including an embed will add to your page load see the chart below

The following are download estimates taken from firebug and a single sample embed. Individual results may vary.
Network Embed Size
Google Maps 237kb
YouTube 380kb
Vimeo 81kb



An embed can be used to display YouTube Content


An embed can be used to display Vimeo content.

Custom Content

An embed can display any web content

Embeds use an intrinsic aspect ratios to embed content responsively. Content will preserve their intrinsic aspect ratio for all browser sizes responsively


Aspect Ratio

An embed can specify an alternative aspect ratio


Specifying a URL

Specifying a url will automatically match to an embed source using the domain of the url.

$('.url.example .ui.embed').embed();

Using Content IDs

Embed is designed to automatically generate urls from content ids. This way your site's backend can store meaningful content metadata and not worry about generating urls.

$('.content.example .ui.embed').embed();

Specifying Programmatically

You can also specify embed settings at run-time in the settings object.

$('.custom.example .ui.embed').embed({ source : 'youtube', id : 'O6Xo21L0ybE', placeholder : '/images/bear-waving.jpg' });

Specifying New Sources

Embed comes with two predefined embed sources, but can be extended with custom sources. Each source specifies default parameters and their mappings to settings, a templated url, and what icon should be used for overlays

Extending $.fn.embed.settings.sources allows you to use other proprietary embeds.

// built in $.fn.embed.settings.sources = { youtube: { name : 'youtube', type : 'video', icon : 'video play', domain : '', url : '//{id}', parameters: function(settings) { return { autohide : !settings.showUI, autoplay : settings.autoplay, color : settings.colors || undefined, hq : settings.hd, jsapi : settings.api, modestbranding : 1 }; } }, vimeo: { name : 'vimeo', type : 'video', icon : 'video play', domain : '', url : '//{id}', parameters: function(settings) { return { api : settings.api, autoplay : settings.autoplay, byline : settings.showUI, color : settings.colors || undefined, portrait : settings.showUI, title : settings.showUI }; } } };


All the following behaviors can be called using the syntax:

$('.your.element') .embed('behavior name', argumentOne, argumentTwo) ;
