      <p id="content">You can change the heading, author name and this content itself. Click on Edit Document to start editing. At this point, you can edit this document and the changes will be saved in localStorage. However, once you reload the page your changes will be gone. To fix it we will have to retrieve the contents from localSotrage when the page reloads.</p>
