Font CSS Properties

The CSS styling variables used to govern font sizes, line heights, and color contrast on the page.

• Input: CSS properties including font-size, color, and line-height.
• Standards:
  1. Minimum Size: Body text size must be at least $\ge$ 1rem (16px / 12pt).
  2. Mobile Scaling: Any font styled greater than 1.75rem (28px / 21pt) must be responsive or utilize mobile-specific CSS overrides.
  3. Contrast Compliance: Text colors must pass the Google Lighthouse check (aiming for WCAG AA standard contrast ratio of 4.5:1 for normal text).

Text Formatting Tags

Styling modifications used within body copy to highlight key terms and make text easy to scan.

• Input: HTML tags like <strong>, <b>, or CSS weight selectors.
• Standards:
  1. Intent Emphasis: Apply bolding strategically to intent-rich keywords and critical phrases that answer user queries.
  2. Styling Consistency: Ensure body formatting is consistent across the site; do not vary weights and styles arbitrarily across paragraphs.
