Fold Away
On hover the button physically folds away on its Y-axis like a closing book — 3D rotateY with perspective for a tactile dismissal.
Fold Away the 13th of 18 designs in the 18 CSS Close Buttons collection. The design is implemented in pure CSS — no JavaScript required. Copy the HTML and CSS panels below into your project. Because the demo is pure CSS, it works in any framework or templating engine you happen to use. The design honours prefers-reduced-motion and uses real semantic markup, so it ships accessibility-ready out of the box.
