Many times I have asked myself why there is no longer a grey or other colour background as there was a few months ago using the
> command. Using a smartphone you can see the color of the background. The visual aspect is important. You can only see the background when you set the
>! command, which makes the question visible when you hover the mouse pointer. Is there any possibility to restore it in all communities?
Just an example without gray background.
Just an example without gray background and formula: $a^2+b^2=c^2$.
