Open Serif is a text-first, encyclopedia-grade design system designed for maximum readability and information density. It embraces a minimalist, utilitarian aesthetic with serif typography, blue hyperlinks, and virtually no decorative elements. Content is king: the system disappears so the knowledge can shine through, accessible to everyone.

Do's & Don'ts

Do

Prioritize content density and readability above all visual flourish
Use blue (#3366CC) for all hyperlinks and interactive text consistently
Use serif fonts for all content; sans-serif would break the encyclopedic tone
Maintain the flat, printed-page aesthetic; the UI should feel like a reference book
Provide a visible table of contents for long-form articles
Ensure every piece of text meets WCAG AAA contrast standards

Don't

Add shadows, gradients, or decorative backgrounds to content areas
Use large images or hero sections; information architecture comes first
Use bright accent colors for UI elements; the palette is deliberately muted
Use more than 2px border-radius; sharp corners reinforce the utilitarian feel
