Syntax and Description

.fadeTo(duration, opacity[, callback])

adjusts the opacity of the matched elements.

duration
A string or number determining how long the animation will run
opacity
A number between 0 and 1 denoting the target opacity
callback (optional)
A function to call once the animation is complete

Its return value is the jQuery object, for chaining purposes.

The .fadeTo() method animates the opacity of the matched elements.

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

The 'fast' and 'slow' strings can be supplied to indicate durations of 200 and 600 milliseconds, respectively.

If supplied, the callback is fired once the animation is complete.
