Sobre esta ferramenta

Visually design a CSS box-shadow - adjusting offset, blur, spread, color, and opacity with live preview - and generates the exact CSS syntax to copy, rather than manually guessing values for the notoriously fiddly box-shadow property.

Como usar esta ferramenta

  1. Select base shadow styleStart with outer or inset shadow based on the component type.
  2. Tune offset and blurAdjust X/Y offset and blur radius until depth looks natural.
  3. Set spread and opacityControl edge softness and intensity for subtle or strong elevation.
  4. Copy CSS declarationUse generated `box-shadow` value directly in your stylesheet.

Por que usar

  • Creates precise shadows faster than manual trial-and-error coding.
  • Live preview makes depth tuning intuitive.
  • Helps standardize elevation styles across components.
  • Outputs clean copy-ready CSS values.

Usos comuns

  • Designing card elevation and modal depth effects.
  • Building consistent hover states for interactive elements.
  • Matching product UI shadows to design specs.
  • Creating neumorphic or soft-layered visual styles.

Dicas para melhores resultados

  • Use lower opacity with slightly higher blur for realistic depth.
  • Stack two subtle shadows for cleaner modern UI elevation.
  • Match shadow direction to your overall light source assumption.
  • Check dark-mode shadow appearance separately from light mode.

Erros a evitar

  • Using harsh black shadows that make UI look outdated.
  • Applying identical shadows to every component regardless of hierarchy.
  • Overusing spread values that create muddy boundaries.
  • Skipping dark-theme tuning where shadows can disappear or look dirty.
