Get to know this tool

CSS Shadow Generator lets you dial in a box-shadow effect using simple sliders and a color picker, with a live preview box so you can see exactly how it will look before copying the CSS.

What is CSS Shadow Generator and Why is it Useful?

Getting a box-shadow value to look right by hand usually means a lot of trial and error — tweaking offsets, blur, and opacity in your code editor and refreshing the browser each time. This tool removes that loop entirely: every slider updates the preview instantly, so you can fine-tune the shadow visually and grab the finished CSS declaration the moment it looks right.

Key Features

  • Horizontal & Vertical Offset: Control how far the shadow is shifted left/right and up/down, from -50px to 50px.
  • Blur & Spread Radius: Adjust how soft and how far-reaching the shadow appears.
  • Opacity & Color Picker: Pick any color and fade it from fully transparent to fully opaque.
  • Live Preview: A sample box updates in real time as you move any slider, so you always see the exact result.
  • Ready-to-Copy CSS: The full box-shadow declaration is generated automatically in the output field.

How to Use This Tool?

  1. Drag the Horizontal Offset, Vertical Offset, Blur Radius, and Spread Radius sliders to shape the shadow.
  2. Adjust the Opacity slider and pick a shadow Color.
  3. Watch the preview box update live to see exactly how the shadow will look.
  4. Copy the generated box-shadow: ...; line from the CSS Code field and paste it into your stylesheet.

Why Choose Our Client-Side Tool?

There's no reason a simple visual styling tool should require a network round-trip. This generator computes everything — the RGBA color conversion and the final CSS string — directly in your browser using JavaScript. Nothing about your design is ever sent anywhere, and the result updates instantly with every slider movement.

Frequently Asked Questions (FAQ)

Does this tool generate text-shadow as well?

No, this tool is focused specifically on box-shadow for elements like cards, buttons, and containers. The preview box demonstrates a box-shadow effect.

Can I create multiple/layered shadows?

The tool generates a single shadow layer at a time. To combine multiple shadows, you can manually chain several generated values together in CSS, separated by commas.

What does the spread radius do?

Spread expands or contracts the shadow's size beyond the element's bounding box. Positive values make the shadow bigger; negative values shrink it.

Is the generated CSS supported in all browsers?

Yes, box-shadow has been supported in all modern browsers for many years, including Chrome, Firefox, Safari, and Edge.
