Use cases
Section headers
Keep category labels or group titles visible while users browse long grouped content.
Local side navigation
Maintain a nearby table of contents or filter panel without pinning it to the viewport globally.
Cautions
- Sticky positioning fails if ancestor overflow or sizing rules block the effect.
- Sticky elements can cover content if their offset and background are not designed carefully.
Accessibility
- Sticky UI should remain visible without obscuring the currently focused or read content.
