title: Can't use w3school HTML include
body: <p>So here's the link to the original w3school article about HTML include using their .js file <a href="http://www.w3schools.com/howto/howto_html_include.asp" rel="nofollow">link</a>.
  <br>
  I literally copied everything from the w3school example, but got this error :</p>
  
  <blockquote>
    <p>w3school.js:131 XMLHttpRequest cannot load file:///C:/Users/KBS-3/Desktop/project_1/html/header.html. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.</p>
  </blockquote>
  
  <p>Here's my index.html</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;script src="http://www.w3schools.com/lib/w3data.js"&gt;&lt;/script&gt;
  
  &lt;body&gt;
  
  &lt;div w3-include-html="content.html"&gt;&lt;/div&gt; 
  
  &lt;script&gt;
  w3IncludeHTML();
  &lt;/script&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>and content.html </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;h1&gt;HELLO WORLD&lt;/h1&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Any ideas to resolve this ?</p>
