The scrollbar-color
CSS property sets the color of the scrollbar track and thumb.
The track refers to the background of the scrollbar, which is generally fixed regardless of the scrolling position.
The thumb refers to the moving part of the scrollbar, which usually floats on top of the track.
Syntax

The first applies to the thumb of the scrollbar, the second to the track. */ /* Global values */ scrollbar-color: inherit; scrollbar-color: initial; scrollbar-color: unset;

Accessibility concerns
When using scrollbar-color
