fadeOut() method in jQuery

fadeOut() in jQuery

The fadeOut() method is used to animate the opacity of the matched elements.

The display style property is set to none once the opacity reaches 0.

Durations are given in milliseconds, higher values indicate slower animations.

fadeOut() will not hide an element that is already considered hidden.

By setting jQuery.fx.off = true all jQuery effects can be turned off globally , which in turn sets the duration to 0.

Syntax 1


  • duration
    • Default value is 400.
    • number - Integer values are given in milliseconds.
    • slow - It denotes 600 milliseconds.
    • fast - It denotes 200 milliseconds.
  • easing - It is optional and is used to specify the speed at which the animation progresses.It can have two values.
    • swing - It is a default value, animation progresses irregular way.
    • linear - it specifies animation progresses at a constant pace.
  • complete - It indicate a function, and it will be executed after the element animation complete.
Syntax 2


  • options - Given below options are optional
    • duration - It can be defined by string or number and is used to determine how long the animation will run.
    • easing - It is defined by string and is used to determine for transition which easing function to be used.
    • queue - It is denoted by Boolean, and is used to determine whether to place the animation in the effects queue. When a custom queue name is used the animation does not automatically start; you must call .dequeue("queuename") to start it. If it is specified as false, the animation will begin immediately.
