Embed YouTube Video
1. In order to embed a YouTube video you must first grab the embed code for the video you wish to embed from the YouTube site.
First navigate to the video on the YouTube website and click the “Share”  button located below the video, then click the “Embed” button  and copy the embed code 
2. Now that you have the embed code copied, navigate to the issue you wish to add the video to and go into the enhancement tools.
In Enhancement tools, select the option called “HTML”
3. Once you are in the HTML editor, select the page and draw a box where you want the video to be placed  and paste the embed code you copied from YouTube in the “HTML” tab .
4. All that is left to do now is change the height and width of the embed video so that it takes up the entire space of the box you drew.
