CSS, PRO Custom CSS, Custom Design

[AlexeiAlexeikov]

Hello, I need help with PRO Custom CSS. I need to make a custom design that turns on when I switch to dark mode (only changing the color of different elements, without changing the font, etc.). The design itself is quite light and does not combine with the elements of a defective dark theme. I use CSS from developers for the dark theme they attach in the training section. There are elements that I can't find how to change their color in this CSS and they don't match at all. For example, the "add" and "edit" buttons (for others they may be called differently, but these functional buttons are still present). Also, some cells in the modal windows are painted in dark-themed flowers (brown).

Questions:

1. Is there a normal commented CSS that we can properly customize ourselves by inserting into "PRO Custom CSS" in the settings, where the color change of each element is specified?

2. This problem leads to the idea of inverting a dark theme to a light one (i.e. when switching to a dark one, we have the same light one) and inserting into "PRO Custom CSS" those changes to the elements from CSS for the dark theme that are clear for what. What will it give us? The elements that were pulled up from the defective dark theme will be pulled up from the default light and at least somehow will be combined with custom CSS, which in my case is executed in a light design. To sum up, how to invert it?
