Box shadows add depth and visual hierarchy to UI elements. The CSS box-shadow property accepts horizontal offset, vertical offset, blur radius, spread radius, and color. This visual tool lets you design shadows by adjusting sliders and seeing the result in real time, including multiple layered shadows for more realistic effects.
box-shadow: 5px 5px 15px 0px rgba(0, 0, 0, 0.35);
Adjust the shadow parameters using interactive sliders: horizontal offset, vertical offset, blur radius, spread radius, and shadow color with opacity. Toggle the 'inset' option for inner shadows. Add multiple shadow layers for realistic depth effects. The preview element updates in real time, and the complete CSS box-shadow property is generated below, ready to copy and paste into your stylesheet.
Box shadows create depth and visual hierarchy in UI design. They are used for card elevation effects in Material Design, dropdown menus and popovers, modal dialog overlays, button pressed and hover states, input field focus indicators, navigation bar separation from content, image frame effects, and creating neumorphism (soft UI) design patterns with inset shadows.
The CSS box-shadow property accepts: [inset] offset-x offset-y blur-radius spread-radius color. Multiple shadows are comma-separated and rendered in stack order (first shadow on top). Blur radius creates a Gaussian blur effect - the shadow extends beyond the element by the blur radius. Spread radius expands (positive) or contracts (negative) the shadow shape. Shadow rendering uses the GPU for hardware acceleration, making it performant even with multiple layers.
box-shadow adds shadow effects around an element's frame. The syntax is: box-shadow: [horizontal offset] [vertical offset] [blur radius] [spread radius] [color]. Example: box-shadow: 4px 4px 10px rgba(0,0,0,0.2).
Yes. Separate multiple shadows with commas: box-shadow: 2px 2px 5px rgba(0,0,0,0.1), 0px 0px 20px rgba(0,0,0,0.05). Multiple shadows create more natural, layered lighting effects.
box-shadow applies to the element's rectangular box. The filter: drop-shadow() function follows the actual shape of the element (including transparent areas and border-radius), making it better for non-rectangular shapes.
Adding the 'inset' keyword creates an inner shadow: box-shadow: inset 0 2px 4px rgba(0,0,0,0.1). This creates a pressed or recessed visual effect.
