Horizontal Scroll Snap

Introduction

In this lab, we will explore the concept of horizontal scroll snap in CSS. The lab will guide you through creating a horizontally scrollable container that will snap on elements when scrolling. You will learn how to use the scroll-snap-type property and scroll-snap-align to create a snap effect and how to control the alignment of the snap. By the end of the lab, you will have a good understanding of how to create a sleek and user-friendly horizontal scrolling layout.

Horizontal Scroll Snap

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

To create a horizontally scrollable container that snaps on elements when scrolling, follow these steps:

1. Use display: grid and grid-auto-flow: column to create a horizontal layout.
2. Use scroll-snap-type: x mandatory and overscroll-behavior-x: contain to create a snap effect on horizontal scroll.
3. Change scroll-snap-align to either start, stop or center to adjust the snap alignment.

Here's an example HTML and CSS code you can use:

HTML

<div class="horizontal-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>
  <a href="#"><img src="https://picsum.photos/id/259/640/640"></a>
  <a href="#"><img src="https://picsum.photos/id/283/640/640"></a>
  <a href="#"><img src="https://picsum.photos/id/288/640/640"></a>
  <a href="#"><img src="https://picsum.photos/id/299/640/640"></a>
</div>

CSS

.horizontal-snap {
  display: grid;
  grid-auto-flow: column;
  gap: 1rem;
  height: calc(180px + 1rem);
  padding: 1rem;
  max-width: 480px;
  margin: 0 auto;
  overflow-y: auto;
  overscroll-behavior-x: contain;
  scroll-snap-type: x mandatory;
}

.horizontal-snap > a {
  scroll-snap-align: center;
}

.horizontal-snap img {
  width: 180px;
  max-width: none;
  object-fit: contain;
