What is CSS Box Shadow Generator?

This CSS box shadow generator lets you visually design a drop shadow by adjusting offset, blur, spread, color, and opacity with sliders, then outputs the ready-to-use box-shadow CSS property. It's built for frontend developers and designers who want precise control without manually guessing pixel and color values. As a css box shadow generator, it also supports layering multiple shadows for more complex, material-design-style depth effects.

How It Works

The tool renders a live preview element and updates its box-shadow style in real time as you adjust horizontal offset, vertical offset, blur radius, spread radius, and color/opacity values using sliders or input fields. Behind the scenes, it simply assembles these values into the standard CSS box-shadow shorthand syntax (and optionally comma-separates multiple shadow layers for compound effects), which you then copy directly into your stylesheet.

Is It Safe to Use?

All shadow generation and preview rendering happens locally in your browser; no design values or project details are sent to or stored on a server.

How to Use CSS Box Shadow Generator (Step-by-Step Guide)

  1. Adjust the horizontal and vertical offset sliders to position the shadow.
  2. Set the blur radius and spread radius to control shadow softness and size.
  3. Choose the shadow color and opacity.
  4. Preview the effect live on the sample element.
  5. Add additional shadow layers for a layered depth effect if desired, then copy the generated box-shadow CSS.

Frequently Asked Questions

What does each value in a box-shadow property control?
The horizontal and vertical offsets position the shadow relative to the element, blur radius softens its edges, spread radius expands or contracts its size, and the final value sets its color and opacity.
Can I create a material design shadow generator style effect with this tool?
Yes, by layering multiple box-shadow values with different blur and opacity settings, you can recreate the soft, multi-layered shadows characteristic of Material Design elevation.
Can I add multiple shadows to one element?
Yes, CSS's box-shadow property accepts comma-separated shadow definitions, and the tool supports building several layered shadows for more realistic depth.
Does a box shadow affect an element's layout or size?
No, box-shadow is purely visual and doesn't affect the element's box model dimensions or push surrounding content, unlike margin or border changes.
What's the difference between blur radius and spread radius?
Blur radius controls how soft and feathered the shadow's edge appears, while spread radius controls how much the shadow itself expands or shrinks beyond the element's size before blurring is applied.
Can I create an inset shadow with this generator?
Yes, most box shadow generators include an inset toggle, which draws the shadow inside the element's border instead of outside it, useful for pressed-button or input field effects.
Is the generated CSS compatible with all modern browsers?
Yes, box-shadow is a well-supported standard CSS property across all current major browsers with no vendor prefixes needed today.
Can I use this box shadow css generator for shadows beyond cards or buttons?
Yes, it works for any element needing depth, such as modals, dropdowns, tooltips, and image overlays, not just the typical card or button use case.
