CSS Box Shadow Generator

The CSS box-shadow property adds one or more shadow effects around an element. Each shadow is defined by horizontal and vertical offsets, blur radius, spread radius, color, and an optional inset keyword. Multiple shadows can be combined with commas to create complex depth effects.

Click the "Add Layer" button to create a new shadow layer. Each layer has its own independent controls for offsets, blur, spread, color, opacity, and inset. Layers are combined in the generated CSS output separated by commas. You can remove any layer by clicking its delete button.

Blur radius controls how soft or sharp the shadow edge appears — higher values create a more diffused, gentle shadow. Spread radius expands or contracts the shadow size — positive values make the shadow larger than the element, while negative values shrink it.
