relly.reltext()

• maintain font-size relative to an element's height, by a specific fraction

• javascript function which maintains the font size of an element relative to the element's own height

  // just call reltext
  relly.reltext()
   
  // alternatively: you can pass parameters, here's an example with the defaults
  const elements = document.querySelectorAll(".relly-reltext")
  const fraction = 5 / 100 // font-size 1em becomes 5% of each element's height
  relly.reltext({elements, fraction})
