Box Shadow Generator Online

Create custom CSS box shadows visually with a live preview and generate production-ready CSS in seconds. This free Box Shadow Generator lets you adjust horizontal and vertical offsets, blur radius, spread radius, color, opacity, and inset effects. Stack multiple shadow layers to build realistic depth, soft glows, or modern Material Design-inspired interfaces, then copy the generated CSS with a single click.

Everything runs directly in your browser, so your work stays private and updates instantly.

The CSS box-shadow property adds one or more shadows around an HTML element without requiring image files. Box shadows are widely used in modern web design to create depth, highlight interactive elements, improve visual hierarchy, and make interfaces feel more polished.

Instead of writing CSS manually, this online Box Shadow Generator provides an interactive editor where you can fine-tune every shadow property and preview the results in real time before copying the generated CSS.

• Horizontal Offset

  Moves the shadow left or right. Positive values move it to the right, while negative values move it to the left.

• Vertical Offset

  Moves the shadow up or down. Positive values move it downward, while negative values move it upward.

• Blur Radius

  Controls how soft the shadow appears. Smaller values create sharp shadows, while larger values produce smooth, diffused shadows.

• Spread Radius

  Expands or shrinks the size of the shadow before blur is applied. Positive values increase the shadow size, while negative values reduce it.

• Shadow Color

  Choose any HEX, RGB, HSL, or RGBA color to match your design. Transparent colors are commonly used to create natural-looking shadows.

• Opacity

  Adjust the transparency of the shadow to make it subtle or more prominent without changing its color.

• Inset Shadow

  An inset shadow is drawn inside the element instead of outside it. Commonly used for pressed buttons, input fields, recessed panels, and neumorphic interfaces.

• Select a shadow color.
• Adjust the horizontal and vertical offsets.
• Fine-tune the blur radius.
• Modify the spread radius if needed.
• Change the shadow opacity.
• Enable Inset for inner shadows if desired.
• Add additional shadow layers for more realistic depth.
• Preview the result instantly.
• Copy the generated CSS and paste it into your stylesheet.

• Simple Shadow

  box-shadow: 0 4px 12px rgba(0, 0, 0, 0.15);

• Layered Shadow

  box-shadow:
    0 2px 4px rgba(0,0,0,.08),
    0 8px 24px rgba(0,0,0,.12);

• Inset Shadow

  box-shadow: inset 0 2px 6px rgba(0,0,0,.2);

Writing box-shadow values by hand can be difficult because even small adjustments to blur, spread, or offsets can significantly change the appearance.
