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

Useful for development. onResize | func | null | Hook by which clients can be notified of resize events. minThumbSize | number | 20 | Sets the minimum size of the thumbs (in pixels).

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 {...}
