Video

Use the video component to display video content hosted on YouTube or Vimeo.

How it works

An image and link to the video are displayed if the user has not accepted “campaigns” cookies.

When these cookies are accepted, the image and link is replaced with the embedded video.

By default, all but essential cookies are rejected to prevent YouTube or Vimeo setting their own cookies without the user’s consent.

Important information:

If the example below shows an image and link and you would like to view the embedded video, accept all cookies through the banner example on the cookies pattern page, then reload this page.
