An ambient glow shadow effect built with pure HTML and CSS that applies a soft luminous aura around elements. It enhances visual emphasis and subtle highlight depth without harsh contrast or heavy elevation.
Usage
Use this component when interfaces require light based visual emphasis, such as feature cards, call-to-action blocks, highlighted panels, or interactive UI elements that benefit from gentle glow styling.
Implementation
The glow effect is created using spread based box shadow layering with low opacity and increased blur radius, producing a diffused luminous edge. Responsive styling ensures consistent visual balance across screen sizes.
