Box Shadow Generator

Box shadows help interfaces communicate elevation, focus, depth, and separation. A subtle shadow can make an element feel clickable; a layered shadow can create realistic depth; an inset shadow can suggest pressed or recessed surfaces. The challenge is tuning offsets, blur, spread, and opacity without guessing in code.

This generator provides a live preview on a checkerboard surface, sliders for every shadow value, color and opacity controls, inset toggles, and support for multiple shadow layers. Each layer can be adjusted independently, then the final CSS is copied as a single box-shadow declaration.

For production UI, less is often better. Prefer low opacity, larger blur, and small vertical offsets for soft elevation. Strong shadows can look heavy in light mode and muddy in dark mode, so preview values in context before shipping them into a design system.
