Scrollbar is the long thin section at the edge of a computer display by which contents on the screen can be scrolled. In this article, you will learn how to to style scrollbars on a website using CSS.

Components of a scrollbar

A scrollbar is made up of two major components; The Track and The Thumb

The Track serves as the base of the scrollbar while The Thumb is what the user drags to scroll within a page.

How To Create Custom Scrollbars

Scrollbars can be customized using the::-webkit-scrollbar vendor prefix.

The -webkit-scrollbar vendor prefix consists of seven different pseudo-elements for styling. They are;

  • ::-webkit-scrollbar for the scrollbar
  • ::-webkit-scrollbar-button the scrollbar buttons (The arrows pointing upwards and downwards)
  • ::-webkit-scrollbar-thumb the draggable scrolling handle
  • ::-webkit-scrollbar-track the track/progress bar of the scrollbar
  • ::-webkit-scrollbar-track-piece the track/progress bar that is covered by the handle.
  • ::-webkit-scrollbar-corner the bottom corner of the scrollbar, where the horizontal and vertical scrollbars meet.
  • ::-webkit-resizer the draggable resizing handle that appears at the bottom corner of some elements.

Here is an example that uses ::-webkit-scrollbar, ::-webkit-scrollbar-track, and ::webkit-scrollbar-thumb pseudo-elements:

body::-webkit-scrollbar {
    width: 10px;    /* width of the entire scrollbar */
}

body::-webkit-scrollbar-track {
     background: #f1f1f1;     /* color of the track/progress bar */
}

body::-webkit-scrollbar-thumb {
  background-color: darkgrey;    /* color of the scroll thumb */
  border-radius: 10px;       /* roundness of the scroll thumb */
}

Here is a screenshot of the scrollbar that is produced with the above CSS: scrollbareg.PNG

Conclusion

The default scrollbar can make your Web app's UI look boring and inconsistent across multiple operating systems. Custom styling will provide you with the benefit of having a unified style across different operating systems and made your UI look even better.

NOTE: If there is no selector before the pseudo-elements, the styles will apply to any scrollbar that may appear on the page.

NOTE: The -webkit-scrollbar vendor prefix is supported by Chrome, Edge, Safari and Opera.
