Thank you

When the screen width gets to mobile size, I can no longer see the coded sections. Why did you remove those? Users on mobile devices would still like to see the coding examples.

The code starts to extend outside the ‘box’ and the only way I could come up with to stop that was reducing the font size, but after an extent the font becomes too small to be legible. I would appreciate any advice you have on how to tackle this problem.
