I have a lineup of cards displayed in a horizontal row. By scrolling left or right, I can navigate through the rest of the cards.
By selecting a card, it expands to reveal a small panel that drops down with an arrow pointing towards it.
As I continue to scroll horizontally, I would like the arrow to smoothly move across the width of the panel. How can this effect be achieved using CSS exclusively?
