100 Lost Species (Website of the Day) — UI design breakdown
A digital memorial that unfolds across time. In 100 seconds, 100 lost species are remembered, before the site itself disappears. Sourced from CSS Design Awards. Use this page as a UI breakdown: reverse-engineer hierarchy, color roles, and interaction cues before you remix ideas into your own screens.
- Study how 100 Lost Species separates primary actions from secondary content—note spacing, type scale, and focal contrast. Recognized as Website of the Day.
- Screenshot the hero and a dense content section side by side to compare rhythm and density.
- Ask: what would break first if this layout were a product dashboard—navigation clarity, scan order, or color contrast?
- Related themes: grid, responsive, scroll, education.
