Content structure · nuanced · v4.6.1
STR-01
Use headings to create scannable structure in help content, onboarding flows, and long-form UI copy. Short UI copy like error messages, tooltips, and confirmations don't need headings.
Pass example
What you'll need: a valid photo ID and a recent utility bill or bank statement.
Fail example
To complete verification you will need to provide a valid government-issued photo ID and you should also have a recent utility bill or bank statement that shows your current address on file with us.

STR-02— Keep paragraphs short. 2-3 sentences max for UI copy and help content.STR-03— Use parallel structure in lists and sequential steps. Each item should follow the same grammatical pattern. In multi-step flows, a final result-state item ('You're ready to go', 'Your account is set up') may shift to declarative when it describes an outcome rather than an action.STR-04— Front-load key information in tooltips and microcopy. Users may not read to the end.STR-05— Group related information together. Don't scatter details across disconnected sections.STR-06— Nest headings hierarchically. Never skip heading levels for visual styling. H1 for page title, H2 for sections, H3 for subsections.
