Building slides scrollers has never been so easy! Let’s dive into CSS Scroll Snap and explore how you can create a fully functional, responsive slideshow using nothing but pure CSS. By the end of this, you’ll be confident in building seamless scrolling experiences that are visually engaging and accessible to everyone.

NOTE: this CSS API is widely available since 2018!!!

Introduction

Creating a seamless scrolling experience is no longer a daunting task. With CSS Scroll Snap, you can craft layouts that effortlessly snap to specific elements, making them perfect for slides scrollers, galleries, or even complex navigation interfaces.

This feature is a game-changer for developers who want to create intuitive and user-friendly designs without relying heavily on JavaScript. It’s fast, efficient, and ensures a consistent experience across devices.

The beauty of CSS Scroll Snap lies in its simplicity and wide browser support. Whether you’re designing for mobile or desktop, this technique ensures that your users stay engaged with smooth, predictable scrolling. Let’s explore how you can implement this powerful feature and why it deserves a place in your developer toolkit.

The Magic of CSS Scroll Snap

CSS Scroll Snap is all about making scrolling precise, intentional, and highly customizable. By combining properties like scroll-snap-type and scroll-snap-align, you can control how elements behave when scrolling. It’s supported by all modern browsers, making it a reliable and accessible choice for UI design. You can create stunning interactive experiences that feel polished and professional without needing to write a single line of JavaScript.

Key Properties:

• `scroll-snap-type`: Defines the scrolling axis and behavior (e.g., x mandatory for horizontal scrolling). This property dictates how snapping occurs along the specified axis, providing a smooth and controlled user experience.
• `scroll-snap-align`: Determines where each item aligns during snapping (e.g., start, center, end). It’s incredibly versatile, allowing you to position items exactly where you need them.
• `overflow`: Works hand-in-hand with scroll snapping (e.g., overflow-x: auto). Without proper overflow settings, scroll snap won’t function as intended, so this is a critical part of your CSS setup.
• `scroll-padding`: Ensures spacing around the snapped elements, improving the visual hierarchy and usability of your layout.

By using these properties together, you can create carousels, sliders, and scrollable galleries that are intuitive and delightful to use. Best of all, they work seamlessly on both touch and non-touch devices.
