Custom Scrollbar Component
"
react-scrollbars-custom
(RSC) is a cross-browser and cross-platform React component that allows you to easily customize the look and feel of your site's scrollbars.The component only renders the necessary horizontal or vertical scrollbars and calculates the sizes automatically. It doesn't emulate scrolling, the scroll behaviour is still native. The code is highly optimized for scrolling performance.
RSC also supports nesting, RTL direction, proper page zoom handling as well as momentum scrolling on iOS."
