Slide numbers, section labels, and progress cues that help readers locate themselves in long decks.
Headers & Footers
Keep Deck Metadata Useful and Quiet
Headers and footers carry navigation, date, brand, and compliance context across slides. Use this OPF reference to choose a repeatable pattern without letting metadata compete with the presentation itself.
Context
Date, version, and appendix markers that make exported or printed decks easier to interpret later.
Branding
Subtle organization, client, or event identifiers that keep a deck attributed without competing with content.
Compliance
Legal, confidentiality, classification, and usage lines for controlled distribution contexts.
Header and Footer Patterns
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.

Header & Footer Rules
Keep Metadata Subordinate
Headers and footers should be the quietest repeatable elements on the slide. If they compete with the title or chart, reduce size, contrast, or density.
Use Master-Level Consistency
Position, type size, and color should remain stable across the deck. Exceptions belong on title, divider, or full-bleed image slides.
Treat Legal Text as a Constraint
Use only the shortest approved legal or classification phrase. Repeated compliance copy is necessary in some contexts, but it should not become the visual center.
