An edge glow hover effect built with pure HTML and CSS that adds a subtle illuminated border animation when users interact with an element. It enhances interactive visual feedback while maintaining clean structural design.
Usage
Use this component when UI elements require highlighted hover emphasis, such as buttons, cards, navigation items, or call-to-action sections that benefit from soft glowing interaction cues.
Implementation
The effect is created using box shadow transitions, border accents, or pseudo element overlays to simulate a glowing edge. CSS controls animation timing, intensity, and responsiveness to ensure consistent behavior across devices.
