The fadeOut() effect presented on the post "How to create Fade Effect in Image Slideshow using JQuery" which I have already posted, makes elements invisible but retains space for them in the document layout. The hide() method, by contrast, removes the elements from the layouts as if the CSS display property was set to none. When invoked with no arguments, hide() and show() simply hide or show the selected elements immediately. With a duration argument, however, they animate the hiding or showing process. hide() shrinks an element's width and height to 0 at the same time that it reduces the element's opacity to 0. show() reverses the process. toggle() changes the visibility state of the elements, it is invoked on, if they are hidden, it calls show(), and it they are visible, it calls hide(). As with show() and hide(), you must pass a toggle() to get an animated effect. Passing true to toggle() is the same as calling show() with no arguments. Note also that if you pass ...

You can create animated visual effects by setting the CSS visibility property, i.e. making elements appearing and disappearing. Along with making an element appear and disappear, we might reduce the value of its opacity property over the certain period. This king of animated visual effect creates a more pleasing experience for user and jQuery makes them easy. jQuery defines simple methods such as fadeIn() and fadeOut() for basic visual effects. You can also use an animate() method for producing more complex custom animations.  Every animation has a duration that specifies how long the effect should last for. You can specify this as a number of milliseconds or by using a string. The string "fast" means 200ms and the sting "slow" means 600ms. If you specify a duration string that jQuery does not recognize, you will get a default duration of 400ms.  $("#animation").fadeIn(); // It fades an element in over 400ms $("#animation").fadeOut("fast...
