scrollbar-width
The scrollbar-width property allows the author to set the maximum thickness of an element's scrollbars when they are shown.
Syntax
/* Keyword values */ scrollbar-width: auto; scrollbar-width: thin; scrollbar-width: none; /* Global values */ scrollbar-width: inherit; scrollbar-width: initial; scrollbar-width: revert; scrollbar-width: unset; Values
<scrollbar-width>Defines the width of the scrollbar as a keyword. It must be one of the following values:
auto | The default scrollbar width for the platform. |
thin | A thin scrollbar width variant on platforms that provide that option, or a thinner scrollbar than the default platform scrollbar width. |
none | No scrollbar shown, however the element will still be scrollable. |
Note: User Agents must apply any scrollbar-width value set on the root element to the viewport.
Accessibility concerns
Use this property with caution — setting scrollbar-width to thin or none can make content hard or impossible to scroll if the author does not provide an alternative scrolling mechanism. While swiping gestures or mouse wheels can enable scrolling on such content, some devices have no scroll alternative.
WCAG criterion 2.1.1 (Keyboard) has been in place for a long time to advise on basic keyboard accessibility, and this should include scrolling of content areas. And introduced in WCAG 2.1, criterion 2.5.5 (Target Size) advises that touch targets should be at least 44px in width and height (although the problem is compounded on high-resolution screens; thorough testing is advised).
