An ambient spread shadow effect built with pure HTML and CSS that applies a soft, evenly distributed shadow around an element. It enhances subtle depth perception and visual separation without strong directional bias.
Usage
Use this component when interfaces require balanced elevation styling, such as cards, modals, feature sections, or dashboard panels that benefit from gentle background separation.
Implementation
The effect is achieved using low offset box shadow values with increased blur and spread, creating a diffused shadow appearance. CSS ensures consistent rendering and responsive adaptability across screen sizes.
