              Reveal CSS Animations
                1 Make an element revealable
              
              Add the CSS class .wow to a HTML element: it will be invisible until the user scrolls to reveal it.
(You can change this CSS class in the WOW settings to avoid name conflicts.)
                <div class="wow">
                Content to Reveal Here
                </div>
                
                  2 Choose the animation style
                
                Pick an animation style in Animate.css , then add the CSS class to the HTML element
                  <div class="wow bounceInUp">
                  Content to Reveal Here
                  </div>
                  You’re done!
Now your animations will be revealed when the user scrolls.
