Keyboard Shortcut Card
A list of shortcuts where each row pops out a full reference card — large action title, big keycaps, plain-English description, three "when to use" bullets, and a related-shortcuts pill row. A richer companion to the compact keycap-pill demo earlier in this collection.
Keyboard Shortcut Card the 10th of 21 designs in the 21 CSS Tooltips 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.
