This small script makes it super easy to make sure your CSS grid transitions gracefully from one state to another.
If the content of the grid changes, or if the grid or one of its children is updated with the addition or removal of a class, the grid will automatically transition to its new configuration.

## How it works
The script registers a `MutationObserver` that activates when the grid or one of its immediate children adds or loses a class.
It uses the FLIP animation technique to smoothly update the grid, applying a counter transform to the children of each item so that they do not appear distorted while the transition occurs.
## Requirements
1. The updates to the grid will have to come from addition or removal of a class. Currently, inline style updates will not trigger transitions.
1. The updates to the grid will have to come from addition or removal of a class or element. Currently, inline style updates will not trigger transitions. (Although you can manually trigger transitions in that case by calling `forceGridAnimation()`)
2. If a grid item has children, they should be surrounded by a single container element.
OK:
Example:
```html
<!-- grid style applied via a class -->
<div class="some-grid-class-that-changes">
<!-- a grid item with a single child -->
<div class="grid-item">
<ul class="some-grid-class-that-changes">
<!-- each grid item has a single direct child -->
<li class="grid-item">
<div>
...child 1
...child 2
<h3>Item title</h3>
<div>Item body</div>
</div>
</div>
</li>
<div>
```
Not going to work:
## How it works
```html
<!-- grid styles applied inline -->
<div style="[grid styles that change]">
<!-- a grid item with multiple children -->
<div class="grid-item">
...child 1
...child 2
</div>
<div>

It should work on container elements without CSS grid applied as well, but was developed with CSS grid in mind.
