A gradient edge border built with pure HTML and CSS that applies a multi color gradient effect along an element’s outline. It enhances visual vibrancy and decorative edge emphasis in modern UI layouts.
Usage
Use this component when interfaces require color rich border styling, such as feature cards, highlighted sections, call-to-action blocks, or portfolio layouts that benefit from dynamic edge visuals.
Implementation
The effect is implemented using CSS gradient backgrounds combined with border or pseudo element techniques, allowing smooth color transitions along the edges. Responsive styling ensures consistent rendering across screen sizes.
