   layout.css — Grid, Navigation und Hilfsklassen

   Ersetzt bootstrap.min.css. Enthalten ist nur, was Templates, RTE-Presets und
   Redaktionsinhalte tatsächlich verwenden. Alle Zahlenwerte, Breakpoints und
   Farben sind unverändert aus der bisherigen Auslieferung (Bootstrap 4.3.1)
   übernommen, damit das Design gleich bleibt.

   Breakpoints: sm 576px · md 768px · lg 992px · xl 1200px

   Die veralteten -ms-flex-Präfixe für IE 10/11 sind entfallen.
