title: Page shows code not rendering
body: <p><img src="https://i.stack.imgur.com/RIr6p.png" alt="enter image description here">I know this is simple question, but i am fighting with it for few hrs, so its better to ask in forum to get help quickly. I have added the following simple html snippet in a TextEdit program and saved the file as webpage(.html). When I run this file in any browser, like safari, chrome or firefox, it shows the same code there instead of rendering this as web page.</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;body&gt;
  &lt;h1&gt;My First Heading&lt;/h1&gt;
  &lt;p&gt;My first paragraph.&lt;/p&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Could someone help me to show this as real web page rather than source code showing?</p>
