Add mobile support

[trvrj]

Is your feature request related to a problem? Please describe.

I think it's probably not, as the app tells me that my mobile browser screen is too narrow and to use at my own risk.

Describe the solution you'd like

I would enjoy using this during downtime at work on my phone. The issue I'm running into is I'm unable to tap the IDE portion and enter text to add or edit the code. When I tap, the cursor appears but the keyboard will not popup. I have tried with Opera Full, Opera Gaming Browser, Chrome, and Samsung's browser with the same issue. It would be great to have mobility functionality so I can learn no matter where I am.

Describe alternatives you've considered

I have used the app on my desktop and it works just fine.

Additional context

The app doesn't support mobile platforms, and adding mobile support for this is not planned. We're working on a new course instead that should support mobile platforms a bit better.

I see. Thank you.
