CSS

  • Try to use classes instead of IDs unless things are absolutely unique
  • One selector per line
  • Support IE 9 and above
  • Use rem over em or px
  • Capitalize hexadecimal
  • Maintain contrast to WCAG AA on normal text, WCAG AAA on large text.
  • Use colors from this palette.

Markdown

  • Do not use fancy quotes, dashes, and such; the Markdown processor will handle that.
