react-gemini-scrollbar

React component for creating custom overlay-scrollbars with native scrolling mechanism for web applications (when needed)

Important:

• It only create the custom scrollbars (bind events, etc) when the OS does not supports “overlay-scrollbars” natively, otherwise leave the scrollbars intact
• IE9+ support

Uses gemini-scrollbar under the hood, check the gemini-scrollbar repo for more information.

Props

name	type	default	description
autoshow	bool	false	Show scrollbars upon hovering

onResize	func	null	Hook by which clients can be notified of resize events.

Customization

You can change the styles of the scrollbars using CSS. Ex:

/* override gemini-scrollbar default styles */

/* vertical scrollbar track */
.gm-scrollbar.-vertical {
  background-color: #f0f0f0
}

/* horizontal scrollbar track */
.gm-scrollbar.-horizontal {
  background-color: transparent;
}

/* scrollbar thumb */
.gm-scrollbar .thumb {
  background-color: rebeccapurple;
}
.gm-scrollbar .thumb:hover {
  background-color: fuchsia;
}

If you want to specify different scrollbar styles for your components, one alternative is to pass a className to the component. Then you can use that className as a namespace when writing your css. Ex:

<GeminiScrollbar className='my-awesome-scrollbar'>...</GeminiScrollbar>

.my-awesome-scrollbar .gm-scrollbar.-vertical {...}
.my-awesome-scrollbar .gm-scrollbar.-horizontal {...}
.my-awesome-scrollbar .gm-scrollbar .thumb {...}
