Our Commentary ​

border-shape! Finally! This is one of those CSS features that feels long overdue. clip-path has been a decent workaround, but a native primitive for custom borders will be a huge win for designers and developers alike. It's going to make complex UI elements so much easier to implement and maintain. I'm genuinely excited about this.
