The CSS Box Shadow Generator is a visual, slider-based tool for building box-shadow declarations without writing CSS by hand. It supports multi-layer stacking, inset shadows, full RGBA color control, and live preview — all in the browser with no setup required.
Adding the inset keyword makes the shadow appear inside the element instead of outside it. This is commonly used for "sunken" or pressed states on buttons and input fields.
The spread radius expands or contracts the shadow in all directions before blur is applied. A positive value grows the shadow; a negative value shrinks it below the element size.
Yes. CSS box-shadow accepts a comma-separated list of shadow definitions. This tool lets you add as many layers as you need — each with its own offset, blur, spread, and color.
Stacking layers creates more realistic depth. For example, Material Design uses three layers at different blurs and opacities to simulate how real light falls on elevated surfaces.
The blur radius controls how soft the shadow edge is. A value of 0 produces a sharp, hard shadow. Higher values spread the blur further and make the shadow look more diffuse.
No. Unlike outline or border, box-shadow does not affect the document flow or element dimensions. It is purely visual and safe to use without worrying about layout shifts.
The box-shadow property is one of the most versatile in CSS. A single element can carry a stack of shadows, each with its own position, blur, spread, and color — enabling everything from subtle card elevation to dramatic neon glows. This generator makes all of that visual and instant.
The full syntax is: box-shadow: [inset] offset-x offset-y [blur-radius] [spread-radius] color. Every parameter is optional except the offsets and color, and you can chain as many definitions as you like with commas. This tool generates the correct shorthand automatically as you drag the sliders.

However, animating them on large elements can cause layout repaints. For animated shadows, consider using a filter: drop-shadow() alternative or animate opacity on a pseudo-element instead.
