The short version

What is CSS Box Shadow Generator?

A CSS box shadow generator is a visual tool for creating shadow effects on HTML elements without writing code by hand.

The CSS box-shadow property adds one or more drop shadows to an element's frame, creating depth and visual hierarchy. Shadows can be placed outside (drop shadow) or inside (inset shadow) the element. This tool lets you control offset, blur, spread, color, and opacity for each shadow layer, with unlimited layering for complex effects. All rendering happens in your browser.

Step by step
