How to change browser scrollbar?

Question

Python

Hello, how can I change the browser scroll bar?

Already 20 minutes looking for how, but damn it, apparently no way :). I certainly found a couple of examples, but they are not enough.

Please write me the shortest documentation, GetStarted for this. Thanks :).
Or, just write what properties to write, and to which element.
It is desirable without the use of javascript, I read on the zebra that it is very, very harmful.

Answer 1

Create a listener function that puts everything it receives into a queue.
This function simply while executes longpoll requests, writes them to the queue without processing, and immediately starts listening further
Create a function for reading this queue:
1) dequeu, if empty - return
2) processing
Spread the second function into several threads and loop

Answer 2

Better use asyncio.

Answer 3

Without js it is possible, but limited and not the same in browsers.
For webkits (the best features, you can do very well)

There are styles for IE/EDGE too There is
no styling option in FF.
js solutions are more cross-browser and provide more options.
