Compliance Pattern

Classification Banner

A top classification label for highly controlled materials, paired with a restrained footer.

classification-banner

Use Case

Security, policy, legal, or regulated decks where the classification must be visible before content.

When to Use

Use only when policy requires classification before the viewer reads the slide content.

When to Avoid

Avoid for ordinary confidential decks; a banner consumes attention and visual space.

OPF Config Options

Slide numbers: Enabled
Slide number text: {{slide.number}}
Date format: Not used
Logo position: Not used
Legal line: Handle according to company policy
Classification line: Internal Use Only
Header content: {classificationLine}
Footer content: {legalLine}
Hide on title slide: No

Zone width and inset

The left, center and right zones of design.header and design.footer sit on the content inset: the slide's padding, the same left and right edge as the body, so a footer lines up with the content above it. They are three columns separated by a small gutter (2% of the slide width).

A zone with no content (no image, text, socials or date) lends its column to its neighbours. A lone zone spans the whole content width, so a long source line stays on one line; left and right together share the free centre; a center zone stays centred on the slide and only widens symmetrically. Right-to-left decks mirror the zones.

Zone text that still wraps past two lines is reported by the opf/furniture-wraps validation warning: shorten it, or move sources to a caption or the speaker notes.

Core 0.22.0 behavior.

Best Practices

Use the exact approved classification vocabulary.

Keep banner height small and consistent.

Reserve accent color for the classification label only.
