.slideDown()
Syntax
$(selector).slideDown([speed,] [easing,] [callback]);
Parameters
All three arguments are optional.
The speed, or duration of the animation, can be indicated as either a number (representing milliseconds) or as a string 'fast' or 'slow'.
duration (optional)- A string or number determining how long the animation will run
callback (optional)- A function to call once the animation is complete
Description
A 'fast' animation is 200 milliseconds whereas a 'slow' animation is 600 milliseconds.
If the speed (aka duration) is omitted, the default speed is 400 milliseconds.
$.slideDown() accepts a callback function, which is executed once the $.slideDown() function has finished executing.
