Design soft, modern box-shadows with a live preview, then copy clean CSS in one click.
Presets
box-shadow: 0px 10px 30px -5px rgba(26, 26, 46, 0.15);Start from a preset or drag the sliders to shape the shadow.
Pick the shadow colour and toggle Inset for an inner shadow.
Copy the CSS and paste it into your stylesheet.
In order: horizontal offset, vertical offset, blur radius, spread radius and colour. Add the inset keyword to draw the shadow inside the element.
Use a large blur, a small vertical offset, a negative spread and a low opacity (10–20%). Dark navy often looks more natural than pure black.
Normal shadows are cheap. Very large blurs on many elements, or animating box-shadow, can cost performance — animate transform or opacity instead.
