Typewriter Reveal
A hidden line types in from zero width using max-width transition, with a blinking terminal cursor via CSS animation.
Typewriter Reveal the 18th of 27 designs in the 27 CSS Card Hover Effects 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.
