How to Create CSS Box Shadows

  1. 1

    Set Shadow Direction

    Use the horizontal and vertical offset sliders to control where your shadow falls. Positive values push the shadow right and down, while negative values move it left and up. Start with small offsets like 2-4px for subtle, realistic shadows.
  2. 2

    Adjust Blur and Spread

    Increase the blur radius to soften the shadow edges for a natural diffused look. Use the spread radius to expand or shrink the shadow area. A blur of 8-24px with zero spread produces the most realistic results.
  3. 3

    Choose Color and Opacity

    Pick a shadow color that complements your design. For realistic shadows, use semi-transparent black or dark gray with 10-30% opacity. For decorative effects, try colored shadows that match your brand palette.
  4. 4

    Copy the Generated CSS

    Once you are happy with the shadow, click the Copy CSS button to grab the ready-to-use code. Paste it directly into your stylesheet. You can also toggle the inset option to create inner shadows for pressed button or input field effects.

Common Use Cases

1

Card Elevation and Depth

Add subtle shadows to cards, panels, and containers to create a layered interface. Light shadows with moderate blur give elements a floating appearance that guides the user's eye through your layout.
2

Button and Interactive States

Use box shadows to indicate hover, focus, and active states on buttons and links. A shadow that grows on hover and shrinks on click provides clear visual feedback without changing the element's position.
3

Modal and Overlay Backdrops

Apply large, diffused shadows to modals, dropdowns, and tooltips to separate them from the page content. This creates a sense of depth that tells users the overlay sits above the main interface.
4

Inset Effects for Form Inputs

Inset shadows create a recessed look perfect for text inputs, search bars, and toggle switches. They simulate a carved-in surface that invites user interaction.

Why use box shadows?

Box shadows add depth and dimension to UI elements. They help create visual hierarchy, draw attention to important components, and make interfaces feel more tangible and modern.

The CSS Box Shadow Generator lets you visually design and fine-tune box shadows without writing code by hand. Adjust horizontal and vertical offsets, blur radius, spread, color, and opacity using intuitive sliders, then copy the generated CSS with one click. Whether you are building card layouts, styling buttons, or creating layered UI components, this tool gives you pixel-perfect control with instant live preview.

Box shadows are one of the most versatile CSS properties for adding depth and visual hierarchy to web interfaces. Combined with other design properties like CSS gradients and glassmorphism effects, shadows help you build modern, polished designs that feel tangible. You can also layer multiple shadows on a single element to create complex lighting effects or decorative borders that would be difficult to achieve with other techniques.

For a complete design workflow, pair this generator with the Color Palette Generator to pick harmonious shadow tints, use the Contrast Checker to ensure your shadowed elements remain accessible, and run your final styles through the CSS Minifier to optimize your production stylesheets. All processing happens in your browser with no data uploaded to any server.

How It Compares

Many CSS shadow tools online require sign-ups, show intrusive ads, or limit the number of shadows you can layer. The FindUtils Box Shadow Generator is completely free with no account needed, supports unlimited layered shadows, and runs entirely in your browser so your design work stays private. Unlike desktop design applications that cost hundreds of dollars per year, this tool delivers the same visual shadow editing experience at zero cost.

Compared to writing box-shadow values manually in a code editor, the visual approach saves significant time. You can experiment with dozens of shadow combinations in seconds instead of guessing pixel values and refreshing your browser. The live preview updates instantly as you drag each slider, giving you the same real-time feedback as tools like Figma or Sketch but without leaving your browser.

Tips for Better Box Shadows

1
Use multiple layered shadows instead of one heavy shadow for more natural depth. Combine a tight, dark shadow with a wide, light one.
2
Avoid pure black shadows. Use dark gray or a tinted color with reduced opacity for a softer, more realistic look.
3
Match your shadow direction consistently across the page to simulate a single light source, which creates visual coherence.
4
For Material Design style elevation, increase both blur and offset proportionally. Level 1 uses 2px offset and 4px blur, while level 5 uses 10px offset and 20px blur.
5
Test your shadows in both light and dark mode. Shadows that look great on white backgrounds may need adjustments on dark surfaces.

Frequently Asked Questions

1

What are the box-shadow parameters?

Box-shadow has: horizontal offset (X), vertical offset (Y), blur radius, spread radius, color, and optional inset. Positive X moves shadow right, positive Y moves it down.
2

What is an inset shadow?

An inset shadow appears inside the element instead of outside. It creates a pressed or recessed effect, commonly used for input fields and buttons.
3

Can I add multiple shadows?

Yes! Click 'Add Shadow' to layer multiple shadows on one element. Multiple shadows can create depth, realistic effects, or decorative borders.
4

What's the difference between blur and spread?

Blur makes the shadow softer and more diffuse. Spread expands or contracts the shadow size. Combine both for natural-looking shadows.
5

How do I create a realistic shadow?

For realistic shadows: use subtle offsets (2-8px), moderate blur (8-24px), minimal spread, and semi-transparent black or gray colors (rgba with 0.1-0.3 opacity).
