Do’s and don’ts

Rules written from the measurements, so a coding agent stays on style.

  • Use #FFFFFF for the page.
  • Keep text in 4 levels: #000000, #202020, #555555, #777777.
  • Use #003366 as the brand accent: header, logo and key highlights.
  • Set headlines in Open Sans with tight tracking (-0.01em).
  • Reuse the measured spacing steps (5px, 15px, 32px).
  • Use 5px corners on most elements; larger surfaces also use 2px and 30px.
  • Use #777777 for body text; it reaches 4.48:1 on #FFFFFF. Keep it for large text or metadata.
  • Add drop shadows for depth; use borders and contrast.
  • Introduce new font families beyond Open Sans.
  • Use #003366 for large backgrounds or body text.
  • Make interface transitions slower than 0.45s.
