Light gray background. Top-left large bold headline "Half A Decade In The Making" with supporting paragraph about CAD simulations and ACF-01 development. Below, five vertical columns separated by thin lines, each topped with a small orange square and bottom black dot. Columns labeled 2018 through 2022 with year titles and body copy; 2019 includes a McLaren F1 photo, 2021 shows a CAD render of a double-wishbone mechanism. Bottom-left orange pill holds left/right arrows with "SWIPE TO EXPLORE" below; dotted progress line extends right.

Key takeaway

Vertical rule columns with orange square markers turn a horizontal scroll into a readable engineering chronology. Mixing inspiration photography with CAD renders tells an R&D story richer than text alone.

Reuse notes

Best for product origin or company history pages with real milestones and assets. Horizontal scroll needs mobile fallback; five-plus columns require strong imagery per stop.
