22 Tailwind CSS Feature Sections

Demos like the Feature Cards with Scroll Reveal and the stat band use CSS scroll-driven animations — animation-timeline: view() ties each card's keyframes to its own position in the viewport instead of the document clock. You pair it with animation-range (for example entry 0% cover 40%) so the card finishes rising as it clears the fold. No IntersectionObserver, no AOS, nothing to initialise. The one trap: it only runs where scroll timelines are supported, so set the finished state (full opacity, no translate) as the default and treat the motion as progressive enhancement — if it is unsupported the card simply shows. Every reveal also sits behind @media (prefers-reduced-motion: reduce), which cancels the transform so content is never hidden from someone who opted out of motion.

The Stat Counters band uses a registered custom property plus a CSS counter. You declare the value with @property --n as an integer starting at 0, animate it to the target on a scroll timeline, then print it with counter(n) inside a pseudo-element's content. Because @property makes the variable animatable, the browser interpolates the whole-number steps for you. Two gotchas: you cannot animate a raw unregistered variable, so skipping the @property rule leaves the number frozen at its start value; and the pseudo-element text is not reliably read by assistive tech, so keep the real figure as plain text in the markup as well. On browsers without scroll timelines the static value shows immediately, which is the correct resting state anyway — the count-up is decoration, not the content.

Yes — the Accordion Feature Cards section uses the native <details name> attribute. Giving every <details> in the group the same name turns them into an exclusive set, so opening one auto-closes its siblings exactly like a radio group, with zero script. Each card's <summary> is already focusable and toggles with Enter or Space, and the open state is exposed to screen readers for free. Two things to watch: the preview pane that updates with the open card is driven purely by the <details> open state through :has(), so a browser without :has() support keeps the pane static rather than broken; and you should still give summary a visible :focus-visible ring, because it is easy to hide the default marker triangle and lose all focus feedback with it.

The Sticky Scroll section pins the left headline column with position: sticky and a top offset while the taller right-hand stack scrolls past it. The usual reason it refuses to stick is an ancestor with overflow: hidden (or auto/scroll) — that creates a scroll container which clips the sticky context, and Tailwind's overflow-hidden on a wrapper is the most common culprit. The second reason is the pinned element's parent being exactly its own height, leaving no distance to travel: the sticky column must sit in a grid track shorter than its scrolling sibling. Also give it a real top- value — position: sticky with no offset behaves like static. The progress rail that fills as you read is a separate scroll-timeline animation and is purely decorative, so it is safe to drop where unsupported.

The Tabbed Product Tour and the editor-window Code Snippet block both drive their panels with hidden <input> radios and :checked plus :has() to swap content — genuinely no script. Each option is a real <label> tied to its input, so it is clickable, and you move between options with the arrow keys because that is native radio behaviour. The honest limitation: this is a radio group, not an ARIA tab widget, so a screen reader announces radio button rather than tab. For a marketing feature strip that trade-off is usually fine and far more robust than hand-rolled role="tablist" focus management. Keep a visible :focus-visible ring on the labels, and never hide the inputs with display: none — use a visually-hidden clip pattern so they stay focusable and keyboard-reachable.

The 3D Tilt cards rest at a slight rotateX/rotateY under a perspective parent and straighten and lift on :hover and :focus-within. Skip the resting tilt when a card holds dense copy or a data table — rotated text is harder to read and reads as broken at small sizes — and skip it on touch-first layouts, where there is no hover so the cards just sit permanently skewed. Because the lift also triggers on :focus-within, keyboard users get the same feedback mouse users do, which is the part most tilt effects miss. Wrap the whole effect in @media (prefers-reduced-motion: reduce) so it flattens to a plain upright card for anyone who opted out of motion, and keep the animated properties to transform and opacity only so hover stays on the compositor and never retriggers layout as the pointer moves.

The collection ships both patterns. The Feature Comparison Table uses a real <table> with <th> scope headers — the right choice when you compare products cell by cell, because a screen reader announces the row and column header for each cell automatically. The Plan Feature Comparison Columns instead renders three separate plan cards and keeps their feature rows aligned across cards — even when one value wraps to two lines — with CSS grid subgrid, so every row shares one track height. The common bug with the card approach is hard-coding row heights to force alignment; that shatters the moment copy wraps differently at another breakpoint. Reach for the real table when the data is a matrix, and for the column cards when each plan needs its own CTA and visual weight. Don't fake a matrix with stacked <div> elements — you lose the header-to-cell association entirely.

The Bento Grid section places five features on a 4×2 CSS grid, where the hero tile spans two columns and two rows (col-span-2 row-span-2) and the smaller tiles fill the remaining cells. The asymmetry comes entirely from per-tile span utilities, not fixed pixel sizes, so the tiles stay fluid. To reflow on small screens, drop the span utilities at the base breakpoint and reintroduce them from md: up — start as a single-column stack, then let md:col-span-2 rebuild the mosaic on wider viewports. The trap is leaving the spans applied at every breakpoint: a two-column span inside a one-column grid overflows its track, and the tile either clips or forces a horizontal scrollbar. Give the grid an explicit grid-auto-rows height so the hero tile's row span has a predictable size to multiply, rather than collapsing to its content.
