 The visibility property allows you to turn on or turn off the visibility of an element. This is used extensively with JavaScript to allow elements to hide or appear on the web page when certain events occur.

Take Note: Element boxes that are set to visibility: hidden still affect layout. If you wish to hide the element box altogether, use the display property with the value of none, display: none;
