/*
 * Fluessige Desktopdarstellung
 *
 * Das Originaltheme begrenzte die komplette Website auf 1920 px und die
 * Inhaltsbereiche auf 1230 px. Bei breiten Monitoren oder verkleinerter
 * Browserdarstellung entstand dadurch ein kleiner Rahmen mit weissen Raendern.
 * Diese Regeln lassen die Flaechen die volle Browserbreite nutzen und skalieren
 * die zentralen Inhalte kontrolliert mit, ohne die Tablet-/Mobilansicht zu
 * veraendern.
