CSS box-shadow for cards, buttons, and modals

Build card-style depth quickly with `offset-x`, `offset-y`, `blur`, `spread`, `color`, and `inset` in one generated CSS value.

Use offset, blur, spread, and color to control direction, softness, spread range, and contrast. Toggle `inset` to convert outer depth into inner panel depth or surface feel.

This tool is for generating searchable, copy-ready CSS shadow recipes and validating them against real backgrounds, dark mode, and your design-system tone before applying to UI components.

Common scenarios

Cards, buttons, modals, and popovers where you need lightweight elevation and visual hierarchy control.

Parameter intent

offset-x/y defines direction, blur defines softness, spread defines spread width, color defines mood, and inset defines inner-leaning depth.

Display checks

Verify contrast and edge visibility on real backgrounds, compare light and dark mode, and ensure shadows align with your design system tokens.

Use the generated output as a first draft. Confirm final results in actual UI preview because rendering can vary by context.

Frequently asked questions

Which shadow values can I adjust?

You can adjust X/Y offset, blur, spread, color, opacity, and inset, plus add or remove multiple shadow layers.

Can I use the generated box-shadow CSS directly?

Yes. The completed box-shadow CSS appears below the preview, and the copy button copies it to your clipboard.

Does the preview update as I change values?

When you adjust sliders or color values, the preview box and CSS output update immediately.
