fadeTo() Effect in Jquery

Description:

jQuery fadeTo() method is used to fading the given opacity for the matched/selected element. It is similar to the .fadeIn method but that method unhides the element and always fades to 100% opacity.

Syntax

.fadeTo( duration, opacity

[, complete ] )

Ex : $(“#div”).fadeToggle(“slow”);

Duration/speed	It specifies the speed of the fadein. The valuse may be slow, fast and milliseconds. (default value: 400). Duration are given in milliseconds and higher values indicate slower animations, not faster ones.
Easing	It specifies the easing function to be used for transition (default value: swing).
Callback	A function to call once the animation is complete.

Example:

From the below code, fadeTo() method will apply opacity of 0.2 to the divFadeBox element. A number between 0 and 1 specifying the target opacity.
