CSS Layout Examples

Layout is the largest group here because it covers both where things sit and how they behave as the page scrolls or the window changes size. Grid and flexbox do the arranging, aspect-ratio holds proportions steady, position: sticky pins an element while its container scrolls past, and scroll-driven animation ties motion to scroll position with no script involved.

The range runs from small self-contained pieces, such as aspect-ratio boxes and split panels, up to whole-page behavior like parallax scenes, reveal-on-scroll sections, and carousels that snap. Scroll-driven animation is the newest technique in this group, so those pages carry browser support notes worth reading before shipping. Running all 40 layout pages at 390 pixels wide on October 13, 2026 produced no console errors and no overflow in any of the three engines.
