CSS overflow: overlay

The overlay property is a non-standard property to make scrollbars display on top of content rather than below it. This feature is being standardized as the scrollbar-gutter property. By default, the overflow-anchor value is auto and it lets you mitigate this jarring user experience by keeping track of the position of an anchor node and adjusting the scroll offset accordingly.
