Definition and Usage

The fadeIn() method gradually changes the opacity, for selected elements, from hidden to visible (fading effect).

Note: Hidden elements will not be displayed at all (no longer affects the layout of the page).

Tip: This method is often used together with the fadeOut() method.



Parameter Description
speed Optional. Specifies the speed of the fading effect. Default value is 400 milliseconds

Possible values:

  • milliseconds
  • "slow"
  • "fast"
easing Optional. Specifies the speed of the element in different points of the animation. Default value is "swing"

Possible values:

  • "swing" - moves slower at the beginning/end, but faster in the middle
  • "linear" - moves in a constant speed
Tip: More easing functions are available in external plugins
callback Optional. A function to be executed after the fadeIn() method is completed
