utils/dom/isvisible

Checks whether the element is visible to the user in DOM:

• connected to the root of the document,
• has no display: none,
• has no ancestors with display: none.

Note: This helper does not check whether the element is hidden by cropping, overflow, etc.. To check that, use Rect instead.

Note: The ancestor lookup crosses shadow DOM boundaries, so a text node sitting directly in a shadow root is resolved against that root's host rather than reported as invisible. Works for open and closed shadow roots alike.

Parameters

element: HTMLElement | Text | null | undefined

Returns

boolean
