Create beautiful, smooth CSS box shadows visually. Generate exact CSS code for your modern web designs without writing a single line manually.

Designing Depth

Shadows are essential for creating depth and hierarchy in web design. A subtle shadow can make a button pop, while a deep shadow can create the illusion of a floating card. However, hand-coding the `box-shadow` property involves juggling X/Y offsets, blur radius, spread radius, and color values—often resulting in trial and error.

Our visual Box Shadow Generator lets you tweak these values using intuitive sliders and see the results instantly on a preview element. Once you're happy, simply copy the generated CSS snippet.

CSS Box Shadow Explained

box-shadow: 10px 10px 5px 0px rgba(0,0,0,0.75);
  • 10px (X-offset): Horizontal distance. Positive moves right, negative moves left.
  • 10px (Y-offset): Vertical distance. Positive moves down, negative moves up.
  • 5px (Blur): How blurred the shadow is. 0 is sharp.
  • 0px (Spread): How much the shadow expands before blurring.
  • rgba(...): The color and transparency of the shadow.

Frequently Asked Questions

Can I add multiple shadows?

Standard CSS allows comma-separated multiple shadows. This tool currently focuses on generating a single, perfect shadow layer.

Does this affect performance?

Heavy use of large blur radiuses or multiple shadows can impact rendering performance on older mobile devices, but modern browsers handle them very efficiently.
