Pro tips

  • Use one consistent elevation scale across the full app — typically three levels: card, modal, and tooltip.
  • In dark mode, reduce opacity and increase blur radius so shadows remain visible against dark backgrounds.

Common mistakes

  • Applying heavy shadows to every element on the page.
  • Dark shadows on dark backgrounds where they are invisible.
  • Forgetting focus styles when styling interactive elements.

Privacy note

The shadow generator runs entirely in your browser. No CSS values, colors, or configuration data are sent to Sounez servers or stored anywhere.

When not to use this tool

Avoid applying complex multi-layer box-shadow values to long scrolling lists or grids with hundreds of items — this can significantly reduce rendering performance on lower-end devices. For large repeated components, consider simpler borders or background differences instead.

Frequently Asked Questions

Can I create inset (inner) shadows?

Yes — toggle the inset option to create a shadow that appears inside the element rather than outside it. Inset shadows are useful for pressed button states, focused input fields, and inner glow effects.

Can I use box-shadow values in Tailwind CSS?

Yes — map the generated CSS values to Tailwind's shadow utilities, or add them as custom shadow values in your tailwind.config.js under extend.boxShadow. You can then use them as utility classes.

Can I stack multiple shadows in one declaration?

Yes — add multiple shadow layers in the generator and copy a single CSS declaration that includes all of them comma-separated. Layering a tight shadow and a diffuse shadow creates more realistic depth than a single shadow.
