heightGroup is a simple, lightweight es2015 helper for matching the height of multiple DOM elements.
The fastest way to get started is like so:
new HeightGroup('.example').watchElements()
The watchElements method will automatically update on page resize.
You can however set your height group into a variable, and match heights at certain points in your code using the matchHeights method.
let example = new HeightGroup('.example')
setTimeout(() => {
example.matchHeights()
}, 3000)
