/*       !!! DIE FOLGENDEN DINGE MÜSSEN VARIABLEN SEIN AUS STYLE_NEW.CSS !!!
    -> Farben
    -> Schriftgrößen
    -> Schriftart (muss normalerweise nicht im style vorkommen)
    -> Radien (Radius)
    -> Icon Sizes
    -> Font Weights
    -> Line Heights
    -> Spacing (Abstände)
    -> Layering (z-index)
    -> container-max (außer es wird breiter/dünner benötigt)
    -> Header height falls benötigt
    -> Transitions
    -> Schatten
    ---> Alle anderen Variablen müssen ebenso verwendet werden, wenn es sich um den Style handelt.
    
    
    Das ist SEHR WICHTIG für einheitlichen Style. Es darf nichts davon hardcoded im <style> vorkommen.
    Wenn eine Style-definition auf mindestens 2 Seiten gleich ist, muss er im globalen style_new.css stehen.
