Dos & Don'ts
Do
- Use Linux Libertine at 700 weight for main headings, ensuring text is in lowercase sentence case.
- Use -apple-system for body text and secondary headings, maintaining a line-height of 21px for optimal readability.
- Apply primary brand color #3366cc for links, primary buttons, and accent elements against a pure white (#ffffff) or black (#000000) background.
- Style primary buttons with #3366cc background, #ffffff text, 8px vertical and 16px horizontal padding, and a specific border-radius of 0px 2px 2px 0px.
- Style secondary buttons with #f8f9fa background, #3366cc text, 6px vertical and 12px horizontal padding, and a 2px border-radius.
- Use base border radius of 2px for small UI elements and 10px/12px for larger containers, avoiding pill-shaped or fully rounded corners.
- Apply a single, subtle shadow (rgba(0, 0, 0, 0.25) 3px 3px 10px 0px) only to modal overlays, never to cards or buttons.
- Maintain a flat design aesthetic with no gradients, using simple 1px borders (#a2a9b1) for secondary interactive elements.
Don't
- Do not use Title Case for headings; strictly enforce lowercase sentence case for all heading levels.
- Do not use gradients of any kind; all surfaces must be solid flat colors.
- Do not use emoji in body copy or headings; keep visual language text-only and professional.
- Do not use serif fonts for body text; reserve Linux Libertine exclusively for headings.
- Do not apply shadows to buttons or standard content cards; reserve shadows exclusively for modals.
- Do not use vibrant or saturated accent colors outside of the primary #3366cc blue.
- Do not use exclamation points or enthusiastic punctuation; maintain a matter-of-fact tone.
- Do not use rounded corners (border-radius > 2px) on primary action buttons.
