A reveal that needs no observer and no scroll listener. animation-timeline: view() hands an ordinary @keyframes block a timeline built from the element's own visibility, so each card fades and rises as it enters the scrollport. animation-range: entry ends that timeline once the card is in, and `both` keeps the finished state instead of playing it backwards on the way out.
The toolbar and submit button stay out of the way until the field they belong to is actually in use. :focus-within matches an element while focus sits anywhere inside it, so the wrapper can expand its own actions row the moment the textarea takes focus — collapsing max-height and opacity, no state to track.
This snippet demonstrates two powerful CSS scroll-driven animations: a reading progress bar that fills as the user scrolls the page (using `animation-timeline: scroll(root)`) and individual cards that fade and lift into view as they enter the viewport (using `animation-timeline: view()`), all achieved with pure CSS, no JavaScript.
