title: Do I need Integrity and crossorigin attributes in Locally Hosted Resources?
body: <p>Bootstrap Using <code>integrity</code> and <code>crossorigin</code> attributes on it's CDN sources like</p>
  
  <pre><code>&lt;script src="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js" integrity="sha384-B0UglyR+jN6CkvvICOB2joaf5I4l3gm9GU6Hc1og6Ls7i6U/mkkaduKaBhlAXv9k" crossorigin="anonymous"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>now my question is if I want to use sources locally from my own hosted server do I still need  those attributes or this will be good enough?</p>
  
  <pre><code> &lt;link rel="stylesheet" href="../css/bootstrap.min.css"&gt;
   &lt;script src="../js/jquery-3.3.1.min.js"&gt;&lt;/script&gt;
  </code></pre>
