  • CSS instruction can devolve into a sight-seeing tour of properties and their effects
  • Values for CSS properties are often selected without any reasoned basis

  • Students begin by assessing a typeface for its most readable size at a given viewport, starting with mobile scales
  • Students then establish a typographic grid via a line-height value that is repeated throughout the stylesheet

  2. Formal research and assessment is needed to objectively determine the approach’s efficacy
