# Embedding video

You can include any iframe in markdown to embed a video. We’ve created a simple way to embed YouTube videos and have them look consistent across your web version.

1. Find the video’s YouTube ID: a code in the URL that looks like this: MqlyxZiDoOA
2. In the markdown, use the ID in this tag: {% include youtube id="MqlyxZiDoOA" %}

This will embed the video in an iframe. (In epub output, you can replace it with a link to watch the video online.)

Note: Our default iframe code gives the iframe a .non-printing class, so that your theme can hide the video from the PDF edition.

For now, this only works with YouTube. If you’re embedding from any other service, instead of using our include tags:

• use their standard embed iframe
• try to select a width of around 850 px
• add style="max-width: 100%;" and class="non-printing" to the iframe tag.
