toggle( speed, [callback] )

Toggle displaying each of the set of matched elements using a graceful animation and firing an optional callback after completion.
The height, width, and opacity of each of the matched elements are changed dynamically according to the specified speed. As of jQuery 1.3 the padding and margin are also animated, creating a smoother effect.
Arguments:
speedString, Number
A string representing one of the predefined speeds ("slow" or "fast") or the number of milliseconds to run the animation (e.g. 1000).
callback (Optional)Function
A function to be executed whenever the animation completes, executes once for each element animated against.
function callback() {
  this; // dom element
}
Examples:

Animates all paragraphs to be shown if they are hidden and hidden if they are visible, completing the animation within 600 milliseconds.

    $("button").click(function () {
      $("p").toggle("slow");
    });
