The interface supports multi-layer stacking, allowing users to create complex depth effects by adding and configuring multiple shadows simultaneously. The tool generates production-ready CSS code that can be copied with a single click, and all processing occurs within the user's browser, ensuring data privacy.

Questions

Box Shadow Generator FAQ

Can I create multiple shadow layers with this tool?
Yes, the Box Shadow Generator supports adding multiple shadow layers. Users can click the Add Layer button to stack several shadows, adjusting each layer's offset, blur, spread, and color independently for complex depth effects.
Does the tool generate valid CSS code?
The generator produces production-ready CSS box-shadow syntax that includes all specified layers, offsets, blur, spread, and color values, which can be copied directly into stylesheets.
Is my data kept private when using this tool?
All processing happens in the user's browser; no data is sent to the server, so design parameters and generated CSS remain private on the device.
What does the spread radius do in a box shadow?
Positive spread values make the shadow larger, while negative values make it smaller than the element's size. It expands or contracts the shadow beyond the offset positions.
