Changing the parameters of the css styles

[uPagge]

It would be convenient if it was possible to change the css color values through some external file or docker variable

In my example, I need to change the block color to yours in order to fit remark42 into the design. It would be better if there was some kind of file, remark-42.sass, where you could set different colors for buttons, background, etc., it is even possible to redefine icons, and specify it for docker image.

That is, my idea is in simple costomization without the need to assemble my own version of the front
