Design beautiful soft shadows, layered elevation, or trendy Neumorphism effects. Copy the CSS instantly.
Shadows are one of those subtle design details that can completely change how a website feels.
A flat button suddenly looks clickable, a card feels like it’s floating, and a modal gains focus
simply because of the way light and shadow are applied. Writing complex box-shadow rules
by hand, however, can be tedious. You often find yourself guessing pixel values, tweaking blur radii,
and adjusting hex codes until something looks “just right.” Our CSS Box Shadow Generator
takes away that guesswork by giving you a visual interface where you can experiment freely and copy
production-ready code instantly.
If you’re building modern UI components, pairing this tool with others like our HTML Color by Code Generator makes the process even smoother. You can quickly grab exact color values and then apply shadows that complement them perfectly.
Neumorphism, often referred to as “Soft UI,” is a design trend that blends minimalism with realism. Instead of elements floating above the background, they appear to be carved out of it. This effect requires a very specific shadow configuration:
Achieving this by hand can be tricky, but with our generator you can simply click the Neumorphism preset and instantly see the effect applied. Designers love this because it saves time and ensures consistency across components.
Standard drop shadows often look harsh or artificial. Modern design systems, like those used by Stripe or Vercel, rely on “Smooth Shadows.” These are created by stacking multiple shadow layers with varying blur radii and opacities. The result is a soft, realistic diffusion of light that feels natural to the eye. With our generator, you can add three or four layers, adjust their spread, and instantly preview how they interact.
For developers working on polished dashboards or client-facing applications, this technique adds a premium feel. And if you’re juggling multiple design tasks, tools like our Image Format Converter can help you prepare assets in the right formats while you fine-tune shadows for the UI.
When working with shadows, less is often more. A subtle shadow can make a button feel tactile without overwhelming the design. On the other hand, layered shadows can be used sparingly to highlight key components like modals or call-to-action cards. Always consider the light source in your design—consistent directionality makes the interface feel cohesive. And remember, shadows aren’t just decorative; they guide user attention and create hierarchy.
Mastering shadows is about balancing creativity with usability. The CSS Box Shadow Generator gives you the freedom to experiment while ensuring your code is clean and ready for production. Whether you’re exploring neumorphism, building smooth layered shadows, or just adding a subtle drop shadow to a button, this tool helps you achieve professional results without the trial-and-error frustration. Combined with other utilities like color pickers and image converters, it becomes part of a workflow that saves time and elevates your design quality.
Simply toggle the Inset checkbox on any layer. This moves the shadow inside the box, creating a depressed or engraved look, which is crucial for input fields or pressed buttons in Neumorphic design.
Generally, no. However, animating large box-shadows (especially with large blur radii) can be intensive for the browser's painting engine. Use them statically where possible, or animate `transform` and `opacity` for better performance.
Yes. This generator automatically converts your selected color and opacity slider into the correct `rgba()` format, ensuring your shadows blend perfectly with any background.
