Change the appearance of field, while editing!

I use simple decoration in my cards, using simple CSS templates! I was curious, whether is it possible for browser window fields or not?

Is there any way, to change the appearance/properties of the field, while editing? It seems, font size, and font type are provided in stock version.

But, Is there a way to go deeper, such as options to change the appearance i.e. Text colour, background colour, Margin etc. by default!

I am on apple eco system.

Thanks!!

This is not possible at the moment, but may be in the future: https://github.com/ankitects/anki/pull/1049
