## Description

Animate-css-grid is a JavaScript library that automatically animates CSS grid layout changes by calculating element position differences during DOM updates. It applies hardware-accelerated CSS transforms using initial and final bounding client rectangles to keep layout transitions smooth. 

The library tracks grid container children automatically through a mutation observer system, triggering transition sequences whenever elements are added, removed, or rearranged. It maintains proper visual proportions for internal contents during reflows by calculating counter-scaling and counter-translation transforms. 

Users can control transition durations, stagger delays, and easing curves using flexible configuration options and callbacks to produce wave-like animation sequences across grid layouts.
