Vertical Scroll Snap

index.html and style.css have already been provided in the VM.

This code creates a scrollable container that snaps to elements while scrolling. To achieve this effect, the following steps are taken:

1. display: grid and grid-auto-flow: row are used to create a vertical layout.
2. scroll-snap-type: y mandatory and overscroll-behavior-y: contain are used to create the snap effect on vertical scroll.
3. scroll-snap-align with either start, stop or center can be used to change the snap alignment.

Here's the HTML and CSS code:

<div class="vertical-snap">
  <a href="#"><img src="https://picsum.photos/id/1067/640/640" /></a>
  <a href="#"><img src="https://picsum.photos/id/122/640/640" /></a>
  <a href="#"><img src="https://picsum.photos/id/188/640/640" /></a>
  <a href="#"><img src="https://picsum.photos/id/249/640/640" /></a>
  <a href="#"><img src="https://picsum.photos/id/257/640/640" /></a>
