Frequently Asked Questions
Why does the corner ribbon require overflow: hidden on the parent?
Overflow hidden clips the ends of the rotated ribbon so it cleanly terminates at the rounded corners of the card.
Can I position the ribbon on the top-left corner?
Yes, switching to Top-Left applies rotate(-45deg) and anchors the ribbon to the left boundary.
