Questions and answers

What is CSS Box Shadow Generator?
The CSS box-shadow property draws one or more shadows around an element, each set by x and y offset, blur, spread, color and an optional inset keyword. This generator stacks as many layers as you need, adjusts each with sliders, offers presets such as Layered, Inner glow and Neon, and copies the CSS.
Can I layer multiple shadows?
Yes. You can add as many shadow layers as you want, each with independent offset, blur, spread, color, and inset settings. Layered shadows are combined in the CSS output, letting you create complex depth effects and neumorphic designs.
