Size Effect

Size Effect

Description: Resize an element to a specified width and height.

  • size

    • to
      Type: Object
      Height and width to resize to.
    • origin (default: [ "top", "left" ])
      Type: Array
      The vanishing point.
    • scale (default: "both")
      Type: String
      Which areas of the element will be resized: "both", "box", "content". Box resizes the border and padding of the element; content resizes any content inside of the element.

When using this effect with the .show() and .toggle() methods, the to argument is used as the starting point and the original size used as the endpoint.
