CSS Scroll Snap Generator: Keyboard & Native Preview
Build horizontal or vertical scroll snapping, compare mandatory and proximity, adjust alignment and insets, and copy matching CSS and HTML.
Enabling local controls…
Scroll container and alignment
Lengths: 0–200 px, applied to all sides. Padding insets the container’s snapport; margin expands an item’s snap area without changing layout gaps. Inputs stay in page memory.
Native scroll preview
Build the preview and code after configuring.
The browser decides snap distance and inertia. Mandatory snapping can hinder long content; proximity thresholds are browser-defined. Verify with real long content, zoom and touch devices.
How to use this tool
Choose axis, strictness, alignment, padding and margin. Build, scroll the focusable preview or use previous/next, then copy CSS and HTML.
When not to use it
Proximity snapping is browser-dependent. Test real touch devices and content sizes; snapping must not hide content or trap page scrolling.
