Create sleek multi-color gradient border outlines using double background-clip layers.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Adjust border thickness in pixels and container corner radius.
Choose dual stop colors and rotate the gradient angle slider.
Copy the clean background-clip padding-box and border-box stylesheet rules.
By layering a solid background on padding-box over a linear-gradient on border-box with border: transparent, the gradient shines through the border perimeter.
No, this double background-clip technique works on a single DOM element without extra wrapper divs.
