It’s very easy to add Common Ninja’s HTML code to uCoz.
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. Now, on your uCoz dashboard, add a new page.
3. Then, in the window that opens up, choose the HTML option below the editor. Next, copy and paste the code you’ve copied before to the editor and click save. That’s it. You should see Common Ninja’s app on the page.
