Fixed Background Parallax Baseline

A fixed-background baseline demonstrates simple parallax depth while documenting mobile and reduced-motion fallback boundaries.

Fixed attachment

Hero Baseline

A fixed background layer sits behind a readable hero card.

Foreground content remains normal document flow and never depends on the background effect.

Editorial Band

A mid-page band keeps the copy panel independent of the fixed layer.

The background position and size are stable across viewport changes.

Static Fallback

A fallback view shows the same composition without viewport-fixed behavior.

The visual design remains valid when attachment becomes scroll.

Accessibility
Reduced motion and constrained mobile contexts can drop to background-attachment: scroll.

Use this as a baseline comparison; richer depth usually needs transform or scroll-timeline.
