/* Answer to: "default font family css" */

/*
  The font family of a text is set with the font-family property.

  The font-family property should hold several font names as a
  "fallback" system. If the browser does not support the first font,
  it tries the next font, and so on. 

  Start with the font you want, and end with a generic family, to let
  the browser pick a similar font in the generic family, if no other
  fonts are available.
