🌫️ CSS Box Shadow Generator
Build CSS box-shadow styles visually and copy the generated CSS.
Why it is useful
It helps front-end builders tune depth, elevation, cards, buttons, and panels without guessing shadow values.
How it works
The browser updates a preview while you adjust offsets, blur, spread, color, and opacity.
Best input
Start with the component background and page background that match your UI.
Design tip
Use subtle shadows consistently so the interface does not feel noisy.
Privacy note
Shadow generation happens locally in your browser.
Important limitation
CSS shadows can look different across backgrounds and displays; test inside the real layout.
Quick answers
Can I copy the CSS?
Yes. The generated box-shadow value is intended for direct CSS use.
Do shadows affect performance?
Very large or animated shadows can be more expensive to render.
Common Use Cases
Tune card elevation
Adjust offset, blur, spread, color, and opacity until a panel has the right depth for your layout.
Create copyable design specs
Generate an exact box-shadow declaration for a handoff note, Storybook control, or CSS token review.
Compare subtle and strong shadows
Quickly test how different shadow recipes feel before applying them across modals, buttons, or nav bars.
CSS Visual Studio workflow
Move between color conversion, palettes, gradients, contrast checks, shadows, radii, buttons, and glassmorphism while keeping generated CSS local to the browser.
