It’s very easy to add Common Ninja’s HTML code to Cornerstone.
1. First, copy the app’s HTML code. To do so, in the app’s dashboard, go to “Add to Website”. Here, click on the green button (it will automatically copy the code).
2. Next, go to your Cornerstone dashboard. From the Elements tab, select “Raw Content”.
3. Paste the code you’ve copied before and that’s it. You should see Common Ninja’s app on your page.
