Box Shadow Generator

Generate clean, modern CSS box-shadow effects with a visual preview.

A well-placed box-shadow can drastically improve the look of a user interface by creating a sense of depth, hierarchy, and realism. However, typing out the perfect box-shadow CSS parameters can involve a lot of trial and error. The Box Shadow Generator is a powerful yet simple tool that allows developers and designers to visually configure shadow effects. By tweaking sliders for horizontal offset, vertical offset, blur radius, spread, and opacity, you can instantly see the results on a preview element. Whether you need a harsh, solid drop shadow for a retro brutalist design, or a soft, diffuse glow for a modern glassmorphism aesthetic, this tool helps you find the exact settings. Stop guessing numbers and start designing beautiful shadows visually. Once ready, copy the clean CSS code straight into your project.

Frequently Asked Questions

What is the difference between blur and spread?
Blur makes the edges of the shadow soft and fuzzy. Spread increases or decreases the physical size of the shadow block before it begins to blur.
Can I have multiple box-shadows on one element?
Yes, CSS allows you to comma-separate multiple shadows. However, this tool focuses on generating one perfect shadow at a time.
Does box-shadow affect performance?
Large, heavily blurred shadows can occasionally cause performance drops on low-end devices during animations, but static shadows are generally very performant.
How do I make an inset shadow?
You can add the 'inset' keyword to your CSS rule, which changes the shadow from an outer drop shadow to an inner shadow.
