jQuery UI Beispiele -Position

Standardfunktionalität

Verwenden Sie Formularsteuerelemente, um die Position zu konfigurieren, oder ziehen Sie das positionierte Element, um seinen Offset zu ändern. Ziehen Sie das übergeordnete Element umher, um die Kollisionserkennung anzuzeigen.

Bildwechsler

Ein Foto-Browser-Prototyp, der die Position verwendet, um die Bilder links, mittig und rechts zu platzieren und sie dann durchzuschalten. Verwenden Sie die Links oben, um die Bilder durchzuschalten, oder klicken Sie auf die linke oder rechte Seite des Bildes, um sie durchzuschalten. Beachten Sie, dass die Bilder bei Größenänderung des Fensters neu positioniert werden.
