How it works
You start with a ready-made template and replace the example text with your content. It's important to maintain the original visual style, like fonts and colors, and not mix it with other templates.
Installation

Vellum
Deep navy canvas with warm-yellow italic Cormorant serifs and a single dusty teal accent. A quiet, scholarly aesthetic.
A single self-contained HTML deck — typography, palette, decorative system, and slide vocabulary are all tuned together. Mixing layouts across templates breaks the system; stay inside this one.
At a glance
- Scheme: dark
- Formality: high
- Density: low
- Slides in demo: 9
Best for
Anything that should feel scholarly, literary, and quietly intelligent: research synthesis, white papers, academic and policy briefs, advisory deliverables, longform editorial pieces, founder reflections. Equally strong for any deck — including tech, business, or creator work — that wants a calm, considered atmosphere instead of energetic visuals.
Avoid for
Contexts that need visual heat or pop — the navy + warm-yellow italic-Cormorant aesthetic is intentionally low-tempo.
Workflow
- Clone
example.htmlinto the user's workspace as the working file. - Replace placeholder content with the user's real headlines, body copy, numbers, names, dates, and section labels. Match existing dimensions when swapping image placeholders.
- Preserve the design system. Never substitute fonts, recolor the palette, restructure the layout grid, or strip decorative elements (corner brackets, paper grain, geometric shapes, illustrated SVGs). They are part of the identity.
- Adjust deck length by duplicating layouts. If the user has more content than the demo holds, duplicate an existing slide of the most appropriate layout. If less, drop slides from the bottom. Update page-number labels.
- Designing missing layouts: if a slide needs a layout the template doesn't have, design it from scratch using the same fonts, palette, decorative vocabulary, spacing rhythm, and component grammar — never bail to a different template.
- Keep the navigation runtime as shipped. If the deck ships an
assets/deck-stage.jsor inline keyboard handler, leave it intact.

FAQ
Can I change the colors and fonts?
No, the design is fixed to maintain the scholarly and elegant visual identity. Changing these elements can break the design system.
What does 'low density' mean?
It means the content is not cramped on the screen, with plenty of white space for more comfortable and focused reading.
How do I add more slides?
You can duplicate existing slides that have a layout similar to what you need. If you have less content, you can remove slides from the end.
