A small javascript plugin for adding an event listener for sticky elements, without the need for an onscroll listener.
Have a look at this demo.
The Sticky Event Listener plugin is licensed under the CC-BY-4.0 license.
This project uses Gulp(4) to compile and minify Typescript to Javascript.
If you are unfamiliar with Gulp, check this tutorial on how to get started.
Run gulp watch in the command-line to put a watch on the files and run all scripts immediately after saving your changes.
