Start playing videos as they are shown or enter the viewport.

The Video component offers two advanced functions for videos. First, it allows you to pause a video whenever it’s hidden with CSS and resume playing once it becomes visible again. In addition, the video can pause when it’s outside the viewport and start playing when entering it.

Secondly, it allows you to mute YouTube and Vimeo videos, which is often needed if they are used as the background of a section.

For example, the Slideshow, Lightbox and Cover components inherit and make use of both functions.


To apply this component, add the uk-video attribute to a <video> element. The video will be paused whenever it’s hidden with CSS and resume once it becomes visible again.

<video uk-video></video>
<button class="uk-button uk-button-default uk-margin" type="button" uk-toggle="target: +">Toggle HTML5 Video</button>

<video src="" controls playsinline hidden uk-video></video>

Autoplay inview

To play a video when it enters the viewport and pause it again when it leaves the viewport, just add the uk-video="autoplay: inview" attribute to a <video> element.

<video uk-video="autoplay: inview"></video>
<video src="" loop muted playsinline uk-video="autoplay: inview"></video>

Automute YouTube or Vimeo

To mute YouTube or Vimeo videos by default, add the uk-video="automute: true" attribute to the <iframe> element.

<iframe src="" width="" height="" frameborder="0" uk-video="automute: true"></iframe>
<button class="uk-button uk-button-default uk-margin-bottom" type="button" uk-toggle="target: +">Toggle YouTube Video</button>

<iframe src=";showinfo=0&amp;rel=0&amp;modestbranding=1&amp;playsinline=1" width="1920" height="1080" frameborder="0" allowfullscreen uk-responsive uk-video="automute: true"></iframe>
