/*
  Anmerkungen:
  1.) min.height: 0 fuer body und inhalt ist gegen einen Bug, vgl.
      http://stackoverflow.com/questions/33859811/understanding-flexbox-and-overflowauto
  2.) height 100% fuer html, body und inhalt sorgt dafuer, dass sich alles
      immer ueber das gesamte Browserfenster ausdehnt.
