Modal Corner
A larger absolute-positioned corner X — the kind you put on lightboxes and image galleries. Hover leaves a soft purple trail behind the cursor.
Modal Corner the 16th 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.
