Visually build CSS box-shadow code with live preview — copy instantly
The CSS box-shadow property adds shadow effects to elements. The syntax is: box-shadow: [inset] offset-x offset-y blur-radius spread-radius color. The inset keyword makes the shadow appear inside the element rather than outside.
Box shadows are used to create card depth, focus rings on form inputs, floating button effects, and neumorphic designs. Multiple shadows can be layered by separating them with commas. Use rgba() colors with low opacity for natural-looking shadows.
