What is CSS scroll snap?

CSS scroll snap is a set of CSS properties that let you control where a scroll container stops after the user finishes scrolling. It creates smooth, precise scroll experiences — like a full-page scroll or a horizontal image carousel — without JavaScript.

What is the difference between mandatory and proximity snap?

'Mandatory' forces the browser to snap to the nearest snap point after every scroll, even if the user barely moved. 'Proximity' only snaps if the scroll position is close enough to a snap point — the browser uses a threshold to decide.

Does scroll snap work on mobile?

Yes. CSS scroll snap is supported in all modern browsers including Safari on iOS and Chrome on Android. It is often used for mobile-first horizontal carousels and full-screen vertical scroll experiences.

What is scroll-padding and when should I use it?

scroll-padding offsets the snap point away from the container's edge. This is useful when you have a sticky header or fixed UI element that would otherwise overlap the snapped content.

Is this tool free to use?

Yes. CSS Scroll Snap Generator is completely free, requires no account, and runs entirely in your browser. Your data never leaves your device.

/* Container CSS */

.snap-container {
  overflow-x: scroll;
  scroll-snap-type: x mandatory;
  display: flex;
}

/* Child CSS */

.snap-child {
  scroll-snap-align: center;
  flex-shrink: 0;
}

How it works: The scroll container gets scroll-snap-type and each child gets scroll-snap-align. CSS scroll snap is supported in all modern browsers — no JavaScript required.
