scrollsnaptype

Scroll snapping is a CSS feature that allows developers to control how scrolling stops on an element. The scrollsnaptype property is used to define the behavior of snapping for scrollable containers. It specifies which axes scrolling should snap to, and the strictness of the snapping.

The scrollsnaptype property accepts two values, which can be combined. The first value defines the axis to snap to: x mandatory, y mandatory, or both mandatory. The second value, optional, defines the strictness: none, mandatory, or proximity. 'mandatory' means that scrolling must end at a snap point, while 'proximity' allows scrolling to end near a snap point.

When scrollsnaptype is set to 'x mandatory', the scroll container will snap to snap points along the horizontal axis. Similarly, 'y mandatory' enforces snapping along the vertical axis. 'both mandatory' applies snapping to both axes. If only proximity is specified, such as 'x proximity', snapping is less strict and might not always occur if the user scrolls past a snap point.

This property is particularly useful for creating interfaces like image galleries, carousels, or long-form content where you want to ensure that users land on specific, predefined points within the scrollable area. It enhances user experience by providing predictable scrolling behavior and can be used in conjunction with other scroll snap properties like scrollsnapalign and scrollpadding.
