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
;;isVisibleelement // => true
