About this tool

What is Box Shadow Generator?

Box Shadow Generator uses the shared CSS Studio engine to combine up to four independently editable shadow layers.

Three simple steps

01
Add a layer, select it and choose a preset or set offset, blur, spread, color and opacity.
02
Mix outer and inset layers while refining each value in the isolated preview.
03
Copy one valid box-shadow declaration containing every enabled layer.

Common questions

Can I edit a preset after selecting it?

Yes. A preset updates only the selected layer, and every control remains editable afterward.

Is Box Shadow Generator private to use?

Yes. CSS text, values and previews are processed locally in your browser and are not sent to Toolnera.
