Atlas · DS134 · Layout: Narrative

Immersive Scrollytelling

The story is revealed by scroll progress and scene changes.

Status in 2026: Active. In current use.
Trend 2027 to 2030: Steady (an editorial projection, not a forecast).
The term: Known technical term or standard.

Definition

The story is revealed by scroll progress and scene changes.

Traits

parallax
sticky scenes

Typical settings: Features, Launches.

When to use it, and when not

Consider it when the task and motivation match: visitors willing to explore narratives. Typical settings: features, launches.

Be careful when the risk below would hurt the main task: long navigation and motion sickness.

The audience is a hypothesis

"Visitors willing to explore narratives" describes a motivation, task or context for which this direction tends to be chosen. It was not measured, and it says nothing about any age, gender or other group.

UX risk and how to reduce it

Risk: Long navigation and motion sickness.

Mitigation and accessibility: Skip, normal scroll and reduced motion.

How to check: Test a prototype against a plain baseline on a real task: completion, time, errors, comprehension, accessibility and preference, segmented by context rather than by stereotype.

Evidence

Indirect: the sources support underlying principles, not a preference for this style.

The sources below support the principles that apply to this term. None of them shows that this style works better or is preferred.

W3C Web Accessibility Initiative 2023 (Standard or guideline): Motion and vestibular disorders.
W3C Web Accessibility Initiative 2021 (Standard or guideline): Cognitive accessibility guidance.

Heuristic scales

Relative editorial judgements from 1 to 5. They are not results of a study and not a measure of quality.

Visual complexity heuristic: 4 / 5 (1 is few visual elements, 5 is many layered elements)
Expressiveness heuristic: 5 / 5 (1 is restrained, neutral, 5 is highly expressive)
Information density heuristic: 2 / 5 (1 is sparse, 5 is dense)

In our library

No design-style recipe in @codeatlasdev/ui implements this term yet. You can still build it from the --ca-* tokens: see Theming.

Prompt for your AI

Paste this into a coding agent. It carries the trade-offs, and asks for a baseline to compare against.

Design this interface in the "Immersive Scrollytelling" direction (layout, narrative): The story is revealed by scroll progress and scene changes.
Visual and interaction traits to use: parallax, sticky scenes.
Main UX risk: Long navigation and motion sickness. Mitigate it: Skip, normal scroll and reduced motion.
Keep it accessible to WCAG 2.2 AA: contrast, visible focus, keyboard operation, 24 px minimum targets, reflow at 320 CSS px and reduced motion.
Keep the content, hierarchy and behavior the same as a plain baseline so the two can be compared. Do not claim the style performs better; the choice should be validated with users.

Limits

The atlas is a broad, living catalogue, not every style that exists. No authority enumerates them, and the classes (movement, aesthetic, design system, layout, pattern, principle) overlap.
The 1 to 5 scores are relative editorial judgements. They are not results of a study and not a measure of quality.
An audience is a hypothesis about motivation, task and context. It was never measured and says nothing about any age, gender or other group.
The sources support underlying principles (visual complexity, legibility, grouping, accessibility, platform conventions). None shows that a particular style works better or is preferred.
The 2027 to 2030 trend is an editorial projection, not a forecast.
Terms in the Future / AI category rest on exploratory work, some of it preprints, with no causal validation.

Supports: Non-essential motion triggered by interaction, such as parallax scrolling, can trigger vestibular disorders (dizziness, nausea, headaches); content should let users turn it off. The criterion is Level AAA.
Does not support: A prevalence figure, or that all animation is harmful. Essential motion is excepted, and the criterion is above the AA level most programs target.
