Folgend mein Probiercode für Zebrastreifen
Sieht ganz gut aus, hat aber den Nachteil, dass bei fokussierten Mails die Tag-Farben von deinem Code übertrumpft werden.
Beispiel: Dein Code bei mir getestet mit einer Nacvhricht im Fokus mit Tag "Wichtig"
Die selbe Nachricht mit meinem Code
Leider weiß ich nicht, wie man diesen Rahmen in der Windows-Version entfernen kann.
Ich füge stattdessen den Code der Datei tree.css der Mac-Version 102 hier ein. Vielleicht findet ihr darin eine Regel, die auf diesen Rahmen zutrifft und entsprechend geändert werden kann
