element-is-visible v1.0.0

element-is-visible

Checks whether a DOM element is visible through various heuristics, such as checking CSS properties, sizing and overflow. The code is extracted from the Selenium project.

In comparison to other stand-alone libraries which perform this function, the alogrithm implemented by Selenium is much more comprehensive and checks more edge cases. It is still a best guess as to whether an element really is visible, for example an element with a very low opacity is counted as visible, even though it probably cannot be seen by an actual human.

Supports JSDOM by skipping the layout and sizing based checks.

Usage

import { isVisible } from 'element-is-visible';

let element = document.querySelector('#some-element');

isVisible(element) // => true
