Syntax

• Inorder to implement the animation to a certain element, first select the element . For example :

  var element1 = document.querySelector('#id1');

• Now it should be passed as the first argument to the constructor as follows

• The above snippet initializes the element with the block reveal animation. The following method invokes the animation

rev1.reveal(revealSettings);

Credits

This is inspired from Mary Lou's Block Reveal Animation Tutorial. As part of a design for my portfolio website, I have used this effect for user's focus. This plugin draws major logic from the article but provides a lean,more options and self descriptive API which can be used to create sleak and superb block animation. I hope you will find this library useful
