Free Online CSS Box Shadow & Border Radius Generator

Visually design beautiful CSS drop shadows and rounded corners. Export clean, cross-browser CSS code instantly for your web design projects.

Designing the perfect shadow for web elements can be a tedious process of trial and error if you are writing the CSS manually. The right shadow can add depth, hierarchy, and a modern feel (like Soft UI or Neumorphism) to your buttons, cards, and modal windows. Our CSS Box Shadow Generator allows you to tweak X and Y offsets, blur radius, spread radius, and opacity visually in real-time.

💡 Developer Tip: Always use `rgba()` for shadow colors instead of solid Hex codes. A black shadow with 15% opacity blends much more naturally into any background color compared to a solid gray shadow. Our tool handles this conversion automatically!

Frequently Asked Questions (FAQs)

What does CSS Box-Shadow do?

The box-shadow property attaches one or more drop-shadows to an element's frame. It accepts values for horizontal offset, vertical offset, blur radius, spread radius, and color. It can also be set to inset to create an inner shadow.

What is Border-Radius?

The border-radius property rounds the corners of an element's outer border edge. You can use it to create perfectly circular buttons (by setting it to 50%) or soft, rounded cards.

Do I need vendor prefixes like -webkit- or -moz-?

For modern web development in 2026, standard box-shadow and border-radius properties are fully supported across all major browsers (Chrome, Safari, Firefox, Edge). Vendor prefixes are largely obsolete for these specific properties, which is why our tool generates clean, standard CSS.

Can I use this for Neumorphism design?

Yes! To create a Neumorphic effect, you typically need to apply two box-shadows to a single element (one light, one dark) on a matching background. While this tool focuses on single shadows, you can generate both and combine them in your CSS.

How to Use This Generator

  • Shift Right/Down (X/Y Offsets): Controls the direction of the light source. Positive values push the shadow right and down, negative values push it left and up.
  • Blur Radius: Higher values create a softer, more diffused shadow. A value of 0 creates a solid, hard-edged shadow.
  • Spread Radius: Expands or shrinks the shadow before the blur is applied.
  • Inset: Check this box to make the shadow appear inside the element, giving it a sunken or pressed-in look.

Once you are happy with the visual preview, simply click "Copy Code" and paste it directly into your stylesheet. It's that easy!
