jQuery delay()

 Jquery is used to end a task late and if a task is in progress, then it works to stop it for some time. In other words, it is done to start some work late.

Syntax:

$(selector).delay (speed)
$(selector).delay (speed, queueName)

Speed and queueName is an optional parameter. Speed specifies the delay of showing elements these possible vales are 'slow', 'fast' and milliseconds.

                $('#div1').delay().fadeIn();
                $('#div2').delay('slow').fadeIn();
                $('#div3').delay(1000).fadeIn();
                $('#div4').delay(2000).fadeIn();
                $('#div5').delay(500).fadeIn();
            });
