Stacking Cards

Cards pile with slight offsets and the top card moves away to reveal the next.

Add a "Card Stack" (also called stacked cards) to [where].
Pile the cards with slight offsets behind one another; each press should swing the top card away to the side and tuck it in at the back, while the rest step forward: smooth with a light, quick feel.
Make it work by keyboard, let screen readers reach every card in order, and use a simple fade for users who prefer reduced motion.

An element stays locked in place during a scroll range while other content or animation progresses.

Add a "Pinning" scroll effect (also called a pinned section or sticky section) to [where].
One panel should stay locked in place while the content beside it scrolls past, switching to match the step being read, and it should let go when the section ends.
Prefer native sticky positioning over hijacking the scroll, and make sure every step still reads well without the pinned panel on small screens.

Scrolling settles onto defined snap points such as slides or sections.

Add "Scroll Snap" (also called scroll snapping or snap scrolling) to [where].
When scrolling stops, the view should settle neatly onto the nearest section so each one lines up with the edge instead of stopping halfway.
Use the browser's native snapping so wheel, touch and keyboard scrolling all keep working, and make sure content taller than the view can still be read in full.

A sticky header reduces in height or size after the user scrolls down.

Add a "Sticky Header Shrink" (also called a shrinking header or shrink on scroll) to [where].
The header should stay at the top and, once the reader scrolls down a little, smoothly shrink into a slimmer bar with a smaller logo, growing back when they return to the top.
Keep the content below from jumping while the header changes size.

Large text lines slide horizontally as the page is scrolled vertically.

Add a "Text Marquee on Scroll" (also called a scroll text marquee or scroll velocity text) to [where].
Large lines of text should slide sideways as the page scrolls down, with alternate rows moving in opposite directions, and slide back when scrolling up.
Tie the movement to the scroll position, keep the long lines from causing a horizontal scrollbar, and keep them still for users who prefer reduced motion.

An element or scene scales up or down as the user scrolls.

Add a "Zoom on Scroll" effect (also called scroll zoom or scale on scroll) to [where].
While the section is held in view, the element should grow smoothly from a small card until it fills the whole view, in step with the scroll, and shrink back when scrolling up.
Scale it without pushing the layout around it, and show it at its final size without the zoom for users who prefer reduced motion.
