Embed an iframe using the Embed Module. This module will give you a lot of options to make your courses more interactive. As long as your favorite online tool lets you share content with an iframe you will be able to embed it to your course.
Here is a few examples of popular services you can use and a short demonstration on how to embed them in Coursio.
Note: The maximum width of an iframe is 730 px. If wider the content will be cropped.
