  <p>Code :</p>
  
  <pre><code>&lt;!-- jQuery (necessary for Bootstrap's JavaScript plugins) --&gt; 
  &lt;script src="js/jquery-1.11.3.min.js"&gt;&lt;/script&gt;
  
  &lt;!-- Include all compiled plugins (below), or include individual files as needed --&gt; 
  &lt;script src="js/bootstrap.js"&gt;&lt;/script&gt;
  &lt;script src="js/typed.js"&gt;&lt;/script&gt;
  &lt;script src="js/particles.js"&gt;&lt;/script&gt;
  &lt;script src="js/app.js"&gt;&lt;/script&gt;
      &lt;script&gt;
      var options = {
      strings: ["HI im am cool", "HI im not cool"],
      typeSpeed: 40
  
      }
  
      var typed = new Typed(".typing", options);
      });
