Web/CSS/scrollbar-color

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.

scrollbar-color: unset;

Values

<scrollbar-color>

Defines the color of the scrollbar.

`auto`	Default platform rendering for the track portion of the scrollbar, in the absence of any other related scrollbar color properties.
`dark`	Show a dark scrollbar, which can be either a dark variant of scrollbar provided by the platform, or a custom scrollbar with dark colors.
`light`	Show a light scrollbar, which can be either a light variant of scrollbar provided by the platform, or a custom scrollbar with light colors.
`<color> <color>`	Applies the first color to the scrollbar thumb, the second to the scrollbar track.

Note: User Agents must apply any scrollbar-color value set on the root element to the viewport.

Accessibility concerns

When using scrollbar-color property with specific color values, authors should ensure the specified colors have enough contrast between them. For keyword values, UAs should ensure the colors they use have enough contrast. See Techniques for WCAG 2.0: G183: Using a contrast ratio of 3:1.
