What is a box shadow generator?

A box shadow generator is a tool that helps you visually create CSS shadow effects for elements such as cards, panels, buttons, and containers. It lets you adjust the shadow and instantly copy the final CSS.

This page supports both normal and inset shadows and provides a live preview for faster UI styling and cleaner CSS output.

Why use box shadows in CSS?

Shadows can help separate layers, improve focus, and make components feel more tangible. Even subtle shadows can improve visual hierarchy in a design. Stronger shadows can add drama or emphasis, while inset shadows can create recessed or pressed effects.

  • Depth: make elements feel lifted above the surface.
  • Hierarchy: help users notice important components.
  • Feedback: support interactive states like pressed buttons.
  • Visual polish: improve the feel of cards, modals, and UI blocks.

What settings affect a box shadow?

The main box-shadow properties control where the shadow appears, how soft it looks, and how far it spreads. Understanding these values helps you build more intentional UI effects.

  • Horizontal offset: moves the shadow left or right.
  • Vertical offset: moves the shadow up or down.
  • Blur radius: controls softness.
  • Spread radius: changes the shadow size.
  • Color: affects the mood and visibility of the shadow.
  • Inset: switches from outer shadow to inner shadow.

When should you use inset shadows?

Inset shadows are useful when you want an element to feel recessed instead of elevated. They are often used for pressed buttons, input fields, soft inner glow effects, or subtle container styling that feels embedded into the background.

Who should use this tool?

This tool is useful for designers, frontend developers, students, UI builders, agencies, and anyone creating CSS-based interfaces who wants a faster way to build polished shadows.
