Examples
Use presets for cards, buttons, dropdowns, floating panels, glows, and inset controls.
Layered shadows

Copy-ready CSS
The output includes the complete box-shadow declaration.
よくある質問
Can I create multiple box-shadow layers?
Yes. Add layers, tune each offset, blur, spread, color, opacity, and inset setting, then copy one CSS declaration.
What are good examples to start with?
Use subtle card shadows for dashboards, dropdown shadows for menus, glow shadows for focus states, and inset shadows for pressed controls.
Does the tool validate values?
Numeric controls are clamped to practical ranges and color inputs require valid HEX values.
Are settings uploaded?
No. Preview, validation, and copy actions run locally in your browser.
