Weekend in Lisbon
Three days of tiles, tarts and trams.
A travel card folded into three zig-zag panels like a brochure. On hover the folds open flat. Each panel hangs from the one above it, so one rotation per panel drives the whole fold.
Also known as: unfold on hover, folded brochure css, zig zag fold card.

Currently previewing #3b82f6.--hfx-size. Every other dimension is in
em, so the whole thing scales together. Currently previewing 16px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
