This page contains a Javascript accessibility widget from a free trial account with userway.org.
If you want to install something similar on your own Skilljar domain, you'll need to sign up for a userway.org account to generate your own Javascript snippet. Click the button in the middle of this page on the left to open the widget and access the accessibility functions.
This demo acts as a proof of concept to showcase that Skilljar can support any accessibility widget that supports embeddable Javascript. To load a widget like this globally on every page of your Skilljar domain, simply add the embeddable Javascript to your Skilljar Domain Theme's Global Head Snippet.
