Animate letters of a text using Blast.JS

Text Animation

Here I have used Blast.JS to encapsulate each letter of the text with <span> having a CSS property – ‘transition-delay’ value just a little later than the first letter and transformed it while clicking the animate button.

You can play with this and can animate any letter any way you want to create interesting effects. This is surely gonna amaze your audience if you use it on your website 😉

       total = tags.length;

      $('#toggleanimate').click(function(){
