What is a CSS Box Shadow Generator?
This tool helps you create the CSS box-shadow property visually. Instead of writing values by hand, you use sliders and color pickers to define the shadow’s position, blur, spread, and color. A live preview shows the result on a sample element. You can also toggle the inset option to make an inner shadow. The final CSS code is generated instantly and can be copied with one click, ready to paste into your stylesheet.
How to Use the Box Shadow Generator
- Adjust offset – The horizontal and vertical offset sliders move the shadow’s position relative to the element.
- Set blur & spread – Increase the blur radius for a softer shadow; use spread to expand or shrink the shadow.
- Pick a color – Use the color picker to choose any color. The tool automatically adds transparency for a natural look.
- Toggle inset – Check the box to place the shadow inside the element for a pressed or sunken effect.
- Copy the CSS – Click "Copy CSS" and paste the
box-shadowdeclaration into your project.
