How to make a box shadow

  1. Start from a ready-made shadow, or adjust the sliders.
  2. Add layers: a tight shadow plus a wide, soft one looks most natural.
  3. Copy the CSS.

Tips

  • Low opacity (8 to 20%) and a negative spread give soft, modern shadows.
  • Inset shadows look pressed in, for inputs and toggles.
  • Change the box and background colors to see the shadow on your own design.

Frequently asked questions

Does box-shadow slow down a page?

Rarely. Very large blurs on many moving elements can, so keep animated shadows simple.
