Design perfect CSS box shadows visually — tweak every parameter in real time and copy the finished code straight into your project.
The CSS Box Shadow Generator gives you visual sliders and controls for every box-shadow parameter — offset, blur, spread, colour, and inset — and shows a live preview as you adjust them. When you're happy with the result, click to copy the ready-to-use CSS declaration. It removes all the trial-and-error of writing box-shadow values by hand and is useful for designers, front-end developers, and anyone building web UIs.

One job, done well. The CSS Box Shadow Generator was built to solve a specific problem cleanly. No feature bloat, no ads, no distractions — just a fast, visual shadow builder.
What CSS properties does the generator control?
The generator lets you adjust horizontal offset, vertical offset, blur radius, spread radius, shadow colour (including opacity), and whether the shadow is inset. These map directly to the CSS box-shadow property values.
Can I add multiple box shadows to one element?
Yes. CSS box-shadow accepts a comma-separated list of shadows. You can layer multiple shadows for depth effects — the generator outputs the complete multi-shadow declaration ready to paste.
What does the inset option do?
The inset keyword moves the shadow inside the element's border rather than outside. This is useful for creating recessed or pressed-in button effects, inner glows, and depth cues inside containers.
Does the generated CSS work in all browsers?
Yes. The box-shadow property is supported in all modern browsers without vendor prefixes. The generated code is clean, standard CSS that works everywhere.
Can I use RGBA colours for a semi-transparent shadow?
Yes. The colour picker includes an opacity/alpha slider, and the generator outputs the shadow using rgba() so you get soft, semi-transparent shadows that blend naturally with any background.
