How to Create an Inverted Color Theme off Existing Theme Using Just Few CSS

[glennrocksvb]

Actually after enabling the 2 preferences I mentioned in my previous post on Firefox, the dark mode works partially. But for some reason, the color inversion does not take effect on the body background whether it's using background image or color. This is weird because the color inversion works for the header section (which has its own background image) as well as on the main content. But it doesn't work on the sides as shown in the screenshot below.
