Web/API/Screen/availTop

Non-standard This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Specifies the y-coordinate of the first pixel that is not allocated to permanent or semipermanent user interface features.

let setX = window.screen.width - window.screen.availLeft;
