Overview
The CSS Box Shadow Generator allows you to visually design complex box shadows for your HTML elements. Adjust offsets, blur, spread, color, and choose between outset and inset shadows, all while seeing a live preview. Copy the generated CSS for easy implementation.
Use Cases
Adding depth and dimension to UI elements like cards, buttons, and modals.
Creating subtle or dramatic shadow effects for visual hierarchy.
Designing modern interfaces with layered looks.
Learning the
box-shadowCSS property and its parameters.Quickly prototyping different shadow styles.
How It Works
Use sliders and input fields to control: Horizontal Offset (how far the shadow extends to the right), Vertical Offset (how far down), Blur Radius (how much the shadow is blurred), Spread Radius (how much the shadow expands), and Shadow Color (including opacity). A checkbox allows you to toggle the inset property, making the shadow appear inside the element. The live preview updates instantly. The generated box-shadow CSS rule is displayed for copying.
Tips for Better Usage
Subtle shadows often look more professional than very dark or large ones.
Multiple box shadows can be layered by comma-separating them for more complex effects (this tool focuses on generating a single shadow layer).
The
insetkeyword creates an inner shadow, which can be used for pressed button effects or carved-out looks.Adjusting the alpha channel of the shadow color is key to controlling its intensity and how it blends with the background.
