/*
  tfsprout documentation theme.

  Cinder ships a deliberately small stylesheet (88 lines) over Bootstrap 3, so
  almost everything visual here is additive rather than a fight with the theme.
  Everything colour-related is expressed as a custom property on :root and
  restated under [data-theme="dark"], which is what makes the theme toggle in
  docs-theme/overrides/main.html a single attribute flip.

  Font sizes are in px rather than rem on purpose: Bootstrap 3 sets
  html { font-size: 62.5% }, so 1rem is 10px on this page, and a few of
  Bootstrap's own rules depend on that root staying where it is.
