Die CSS3-Implementierung von Karussellbildern wird hauptsächlich durch CSS: Background-Position und CSS3: Animation implementiert. Und um dieses Karussell umzusetzen, benötigen Sie ein Bild mit vier horizontal verbundenen Bildern.
Hinweis (Internet Explorer 10, Firefox und Opera unterstützen die Animationseigenschaft. Safari und Chrome unterstützen die alternative Eigenschaft -webkit-animation.)
