firefox上的自定义滚动条[关闭]

I need custom scrollbar on my website but i dont know how to do it. Something like this: https://source.nbot.eu/. I alredy tried something but nothing happend.

Thanks!

The scrollbar bugs are already open in Firefox's ToDo list in BugZilla. So technically this is not possible unless you use a JavaScript based solution like NiceScroll JS.

To use NiceScroll JS, you need to include the script:

<script src="jquery.nicescroll.js"></script>

And activate it:

$(document).ready(function() { 
  $("html").niceScroll();
});
