CSS Box Shadow Generator (Elevation & Inset Shadows)
Design modern layered box shadows visually and copy clean CSS box-shadow declarations.
TL;DR: CSS Box Shadow Generator provides visual sliders to configure offset, blur, spread, and multi-layer CSS elevation shadows.
How Does the CSS Box-Shadow Property Work?
The CSS `box-shadow` property attaches one or more drop shadows to an element's frame. It accepts up to 6 parameters: `inset` (optional inner shadow), `X-offset` (horizontal distance), `Y-offset` (vertical distance), `blur-radius` (softness of edge), `spread-radius` (expansion/contraction of shadow size), and `color` (typically semi-transparent RGBA).

Frequently Asked Questions
- It is an interactive design tool that allows developers to visually configure depth, blur, spread, and color for element drop shadows and copy clean CSS code.
- Layering multiple subtle box-shadow declarations (e.g. `box-shadow: 0 4px 6px -1px rgba(0,0,0,0.1), 0 2px 4px -2px rgba(0,0,0,0.1);`) creates realistic optical depth.
- Blur radius controls the gradient softness and feathering of the shadow edge; spread radius physically expands or shrinks the size of the shadow footprint.
- The `inset` keyword renders the shadow inside the element's border box, creating a recessed, pressed, or hollow visual effect.
- Neumorphism combines two opposing shadows: one dark shadow offset to the bottom-right and one light/white shadow offset to the top-left on matching background colors.
- Yes. `box-shadow` is a standard CSS3 property with 100% support across modern desktop and mobile browsers.
- No. Box shadows are rendered as paint operations and do not alter element layout geometry or trigger layout reflow.
- Yes. Multiple shadows can be chained together with commas in a single `box-shadow` declaration.
