How to create customization panel for html document?

Question

css

Good day, please advise. How to create a theme customization popup panel for a regular HTML document.

The fact is that I created it, but there is a problem of replacing the color of the elements, in particular on hover. As I understand it, you need to apply styles to all elements through jquery, but the difficulty is that there are a lot of elements. Maybe there is a ready-made plugin to which you can pass classes and values ​​​​for replacement, or is it better to create a separate dynamic class? Or good stuff on the subject.

I want to implement something like this Style Switcher(a) wrapbootstrap.com/preview/WB0412697 , but is it possible not to create several css files, but simply change the representation of the elements themselves.

If anyone has had a similar problem, please don't leave my question unanswered.

This task is for telepaths. Only no offense, it is clear that you tried to convey the problem, but it is not clear from this what needs to be done and what the problem is. Perhaps if you give a link, then there is a chance. And remove the phrase about cookies from the question.
