/*
In der externen Datei "w3-standard.css" stehen alle Möglichen Anweisungen, die nicht ausschließlich für diese Vorlage notwendig sind.

CSS-Angaben für eigene, zusätzliche oder abgeänderte Formatierungen hab ich in dieser zweiten Datei "w3-verein-02.css" abgelegt. Da diese 2. CSS-Datei nach der "w3-standard.css"</p> geladen wird, kann ich damit auch Anweisungen aus der ersten aufheben / überordnen und ergänzen. So habe ich hier z.B. die CSS-Angaben für die Terminliste notiert.
