Archiv-Modus von Basti1012 Lösungspage

Hallo, ich habe eine Liste auf meiner Homepage und hinter jedem Listeneintrag erscheint nach und nach ein Häkchen. Nun möchte ich jedes Mal, wenn ein Häkchen angezeigt wird, einen kurzen Ton abspielen. Aber leider habe ich keine Ahnung wie ich das machen könnte.. Kann CSS3 das machen? Oder verwende ich JS? Es sollte aber keine „onClick“- oder „onHover“-Funktion sein, da der Sound ja immer dann abgespielt werden soll wenn der Haken dargestellt wurde, d.h. opacity = 1
