About This Tool

Free CSS box-shadow generator — visually adjust horizontal and vertical offset, blur radius, spread, color, and opacity with sliders, stack multiple shadow layers for realistic depth, and copy the exact `box-shadow` CSS instantly. No sign-up, no upload, entirely browser-based. Designers and developers use this to create soft card shadows, glowing button effects, neumorphic UI, and layered depth effects without guessing pixel values through trial and error in dev tools. A live preview card updates in real time as you adjust each control, and you can add multiple shadow layers (comma-separated in CSS) to build more complex, realistic lighting effects.

    Use sliders to set X/Y offset, blur, spread, color, and opacity.

    Click "Add Shadow" to stack multiple shadows for more realistic depth.

  3. 3

    Copy the CSS

    Copy the generated `box-shadow` property directly into your stylesheet.

Frequently Asked Questions

What is the difference between blur and spread in box-shadow?+
Blur radius softens and fades the shadow edges — larger values make it more diffuse. Spread expands or contracts the shadow's size before blurring is applied.
Can I create an inset (inner) shadow?+
Yes, toggle the "inset" option to create a shadow that appears inside the element's border instead of outside it.
How do I stack multiple shadows in CSS?+
Separate multiple shadow definitions with commas in the box-shadow property — this tool generates that comma-separated syntax automatically when you add layers.
