The Riverside Seed Swap notice needs predictable card sizes even when someone adds a long message.
The .card rule sets a 14rem preferred width and a 100% maximum so it can fit a narrow container. Its max-height: 7rem limits the height; overflow: auto lets a long note scroll rather than spill out. The row arrangement is supplied for this example; Flexbox comes later.
Scroll the longer note inside its card. Then change .card's overflow to visible, run the preview, and see the text spill below its boundary. Restore auto before the exercise.
The long note remains inside its card and can be scrolled; the shorter note fits without scrolling.
Change one CSS value, then run the preview.
Restore the original value before continuing.
