Cooler jQuery-Vollbild-3D-Fokuskarten-Animationseffekt_jquery

Dies ist eine weitere sehr gute jQuery-Fokuskartenanimation. Ihre Besonderheit besteht darin, dass die gesamte Fokuskarte grundsätzlich im Vollbildmodus angezeigt wird, was der gesamten Fokuskarte auch einen 3D-visuellen Effekt verleiht Die Fokuskarte Der Bildwechsel ist sehr flüssig und recht praktisch.
