{{CSSRef}}
The **`scroll-snap-type`** [CSS](/en-US/docs/Web/CSS) property sets how strictly snap points are enforced on the scroll container in case there is one.
{{EmbedInteractiveExample("pages/css/scroll-snap-type.html")}}
Specifying any precise animations or physics used to enforce those snap points is not covered by this property but instead left up to the user agent.
## Syntax
```css
/* No snapping */
scroll-snap-type: none;
/* Keyword values for snap axes */
scroll-snap-type: x;
scroll-snap-type: y;
scroll-snap-type: block;
scroll-snap-type: inline;
scroll-snap-type: both;
/* Optional keyword values for snap strictness */
/* mandatory | proximity */
scroll-snap-type: x mandatory;
scroll-snap-type: y proximity;
scroll-snap-type: both mandatory;
/* Global values */
scroll-snap-type: inherit;
scroll-snap-type: initial;
scroll-snap-type: revert;
scroll-snap-type: revert-layer;
scroll-snap-type: unset;
```
### Values
- `none`
- : When the visual {{Glossary("viewport")}} of this scroll container is scrolled, it must ignore snap points.
- `x`
- : The scroll container snaps to snap positions in its horizontal axis only.
- `y`
- : The scroll container snaps to snap positions in its vertical axis only.
- `block`
- : The scroll container snaps to snap positions in its block axis only.
- `inline`
- : The scroll container snaps to snap positions in its inline axis only.
- `both`
- : The scroll container snaps to snap positions in both of its axes independently (potentially snapping to different elements in each axis).
- `mandatory`
- : The visual viewport of this scroll container must snap to a snap position if it isn't currently scrolled.
- `proximity`
- : The visual viewport of this scroll container may snap to a snap position if it isn't currently scrolled. The user agent decides if it snaps or not based on scroll parameters. This is the default snap strictness if any snap axis is specified.
> **Note:** If the content in the snap port is changed (e.g. added, moved, deleted, or resized) or the value of any scroll snap-related property (e.g. `scroll-snap-type` or `scroll-margin`) is changed, the scroll container will be [resnapped](https://drafts.csswg.org/css-scroll-snap/#re-snap) according to the latest value of `scroll-snap-type`.
