title: Horizontal scroll snap
tags: interactivity,intermediate
---
Creates a scrollable container that will snap on elements when scrolling.
- Use `display: gird` and `grid-auto-flow: column` to create a horizontal layout.
- Use `scroll-snap-type: x mandatory` and `overscroll-behavior-x: contain` to create a snap effect on horizontal scroll.
- You can use `scroll-snap-align` with either `start`, `stop` or `center` to change the snap alignment.
