<div
x-data="{ isOverlap: $overlap('#TargetEl') }"
x-on:resize.window="isOverlap = $overlap('#TargetEl')"

In this example we check for an initial overlap and then use Alpine JS
resize.window
listener to check while resizing the window.
See the example in action on Check Elements are Overlapping - HyperJS.
