How to remove the Blue Line around the TinyMCE-5 editor - inline mode

Question

Can anyone help with how to remove the Blue Line around the TinyMCE 5 Editor?

Specifically, when using the 'inline' implementation of Distraction-Free, which shows when the editor is active.

Thanks RobinJoe.

I found the answer on the Tiny 'inline' CodePen. This does it:

  <style>
  * [contentEditable="true"]:focus
  { outline: 0px ; }
</style>
