Frequently Asked Questions
How do diagonal corner ribbons stay contained?
The parent card container must have 'position: relative' and 'overflow: hidden' so the rotated ribbon clips cleanly at the card boundaries.
Can I adjust the ribbon rotation angle?
Standard corner ribbons use 45deg (or -45deg for top-left) for symmetrical corner diagonal positioning.
