2 layers applied

box-shadow:
  0px 10px 30px -5px rgba(0, 0, 0, 0.10),
  0px 4px 12px -2px rgba(0, 0, 0, 0.08);

How to create soft layered shadows

  1. 1Configure horizontal offset, vertical offset, blur radius, and spread.
  2. 2Add multiple layers to achieve smooth modern elevation styles.
  3. 3Copy the resulting CSS `box-shadow` declaration.

Layered Shadows for Realistic Depth

Single-layer shadows look artificial. Stacking 2 to 4 subtle shadow layers creates the smooth optical falloff used by Stripe and Tailwind CSS.

Architecture & Privacy

  • High-precision multi-layer stacking: Renders composite drop shadows with GPU compositing optimization.
  • Full Inset shadow support: Correctly positions inner depth effects alongside outer elevations.
  • Tailwind arbitrary syntax generator: Outputs ready-to-paste shadow-[...] values with underscore syntax mapping.
  • Adaptive canvas testing: Switch between light, dark, and dot-grid backdrops to audit shadow legibility.
