CSS Box Shadow Generator — Design Perfect Shadows for Your UI Instantly

The CSS Box Shadow Generator from TechNeg Tools helps designers, developers, and web creators craft beautiful, realistic shadows effortlessly.

Instead of guessing values or tweaking endless CSS lines, you can now adjust sliders, colors, and opacity visually — and get perfect shadow code instantly.

Whether you’re designing cards, buttons, modals, or floating UI elements, this free generator gives you full creative control over your box-shadow styling.

🎨 What Is CSS Box-Shadow?

The box-shadow property in CSS allows you to add shadow effects around an element’s frame. It’s one of the simplest yet most powerful design properties in modern web styling.

It can make elements look elevated, soft, glowing, inset, or even simulate depth and lighting realism — all with a few values.

Here’s the basic syntax:

box-shadow: offset-x offset-y blur-radius spread-radius color inset;

Each parameter defines:

  • offset-x: How far the shadow moves horizontally
  • offset-y: How far the shadow moves vertically
  • blur-radius: How soft or sharp the shadow edges are
  • spread-radius: Expands or contracts the shadow size
  • color: The shadow color (often rgba() for transparency)
  • inset (optional): Creates an inner shadow instead of an outer one

By combining these values cleverly, designers can create subtle elevation, glowing effects, and modern neumorphic designs.

🧩 Example Use Cases

🧱 1. Card Component

.card {
  background: #fff;
  border-radius: 10px;
  box-shadow: 0px 6px 18px -6px rgba(0, 0, 0, 0.15);
}

This produces a subtle lifted card — perfect for modern dashboards and landing pages.

💡 2. Button Shadow

.button {
  background: #111;
  color: #fff;
  box-shadow: 0px 3px 10px rgba(0, 0, 0, 0.25);
}

A soft drop shadow gives depth and tactile feedback to buttons.

🌈 3. Glowing Effect

.glow {
  background: #fff;
  box-shadow: 0px 0px 20px rgba(0, 150, 255, 0.3);
}

This mimics a subtle neon glow — great for highlighting active states.

🧠 4. Neumorphism UI

.neumorphic {
  background: #f0f0f0;
  border-radius: 12px;
  box-shadow: -8px -8px 20px rgba(255,255,255,0.8),
               8px 8px 20px rgba(0,0,0,0.08);
}

A dual-layer shadow creates a soft 3D embossed effect that’s trendy in minimalist interfaces.

📈 Best Practices for Using Shadows in UI Design

  1. Use shadows sparingly – Too many shadows can overwhelm your layout.
  2. Keep opacity low – Subtle shadows (opacity between 0.08–0.15) feel modern.
  3. Use multiple layers – Realistic shadows often have two or more layers (a soft large one and a tighter dark one).
  4. Match light direction – Consistency across elements makes your UI feel coherent.
  5. Avoid pure black – Use semi-transparent gray (rgba(0,0,0,0.1)) for natural softness.
