Hallo liebe Community, ich wollte ein Kontaktformular machen und habe jetzt folgende Frage zu der Textarea. Code ist unten. 1) Was für einen Befehlt gibt es, um die kleine Ecke zum selber vergrößern/verkleinern zu verbieten? 2) Die styleatribute von dem Input "text" kann ich nicht auf die Textarea anwenden, bei Textarea gibt es iwi Unterschiede von focus und valid. Kann mir da jmd. helfen, die gleiche Animation darauf zu beklommen?
