Browser-local color and CSS utility

CSS Box Shadow Generator

Build a validated CSS box shadow with bounded numeric controls and a local live preview.

Shadow preview

Output updated.

Method

Offsets are bounded to ±100px, blur to 0–200px, spread to ±100px, and opacity to 0–1. Only validated tokens enter the preview or CSS.

Boundaries

Every successful output comes from labeled structured controls. Generated colors are not automatically accessible, professionally approved, or suitable for every design. Validate contrast separately when needed.
