Perceptible

Perceptible

A basic implementation to detect visibility of DOM Elements with Zero dependencies.

Perceptible can be used to detect viewability of any DOM element that the user is currently looking at. A Element may be part of the page but not under current viewport (due to user scroll), perceptible helps to calculate viewability for such elements for analytics and other purpose.

In addition to view port, it also considers page focus and switching of tabs while calculating the visibility of element. Entire visibility duration of the element is also reported.

Perceptible is highly configurable and easy to use.
