.fadeTo( duration, opacity [, easing] [, callback] ) ExamplesTop

Adjust the opacity of the matched set, optionally providing an easing and/or a callback function.

In the example below when the left button is pressed we fade the first image to an opacity of 0.75 with a slow duration.

When the middle button is pressed we use 'swing' easing with an opacity of 0.3 with a fast duration.

When the right button is pressed we use a duration, easing and a callback to fade the last 3 images to their specified values.

$(function(){
  $('#btn13').on('click', function() {
    $('#curry4').fadeTo('slow', 0.75);
  });
  $('#btn14').on('click', function() {
    $('#pie10').fadeTo('fast', 0.3, 'swing');
  });
  $('#btn15').on('click', function() {
    $('.pie11').first().fadeTo('fast', 0.8, 'linear', function() {
      // using 'callee' so we don't have to name the function
      $(this).next().fadeTo(1200,  0.4, arguments.callee);
    });
  });
});
