Dark mode readibility

[balzdur]

tl;dr:

This is not a bug, but an enhancement. Dark mode related.

Context

By using the dark mode theme in the documentation, I find the colored opacity background distracting due to the blured background image. In comparison, the bg image is removed with the light mode (which I use for that particular reason).

IMO, removing the blured bg image or using non alpha background colors for documentation pannel could really improve the readibility.

Examples with a non alpha bg color

How it is right now (in red, this is the disturbing parts, scrolling makes it worse since the bg image is fixed)
