Read Original

This article details a CSS solution for implementing rounded gradient borders on elements with semi-transparent or blurred backgrounds. It explains the use of the `::before` pseudo-element, `border-box` background, and the `mask` and `mask-composite` properties to create a composited border shape. The technique, originally found in a forum post, is broken down step-by-step with code examples and a CodePen demo.
