The CSS Box Shadow Generator lets you visually design box shadows and copy the production-ready CSS code with a single click. Box shadows add depth, elevation, and visual hierarchy to UI elements like cards, buttons, modals, and navigation bars. Instead of guessing pixel values and repeatedly refreshing your browser, use the interactive sliders to adjust horizontal offset, vertical offset, blur radius, spread, and color — with an optional inset toggle for inner shadows. The preview updates in real time so you see exactly what your shadow looks like. All processing is client-side in your browser with no server communication, making it fast, private, and always available.

About CSS Box Shadow Generator
The CSS box-shadow property adds one or more shadows to an element. It accepts horizontal offset, vertical offset, blur radius, spread radius, and color — plus an optional inset keyword for inner shadows. While the syntax is straightforward, getting the values right by trial and error in a code editor is tedious. This visual generator provides slider controls for each parameter and a live preview box that shows the shadow in real time. When you are satisfied with the look, copy the generated CSS and paste it directly into your stylesheet. The tool is particularly useful for creating material design elevation, neumorphism effects, and subtle depth cues in modern web interfaces.
How to Use CSS Box Shadow Generator
- Adjust the Offset X and Offset Y sliders to position the shadow horizontally and vertically.
- Set the Blur radius for softness and Spread for shadow size.
- Pick a Color using the color picker (with opacity if needed).
- Check Inset to create an inner shadow instead of an outer one.
- Click Copy CSS to copy the generated code and paste it into your project.

Technical Details
The generated CSS follows the standard box-shadow syntax: [inset] offset-x offset-y blur spread color. Offset values can be negative (shadow moves left or up). Blur radius must be non-negative; higher values produce softer shadows. Spread expands (positive) or contracts (negative) the shadow relative to the element size. The color can include alpha transparency for subtle effects (e.g., rgba(0,0,0,0.2)). The tool outputs standard CSS supported by all modern browsers without vendor prefixes.
Conclusion
The CSS Box Shadow Generator simplifies the process of creating perfect box shadows with a visual, interactive interface. Get production-ready CSS in seconds without trial-and-error coding — all running privately in your browser.
