<textarea id="valid-elements">
  <p style="text-align: center; font-size: 15px;"><img title="TinyMCE Logo" src="//www.tiny.cloud/images/glyph-tinymce@2x.png" alt="TinyMCE Logo" width="110" height="97" />
  </p>
  <h2 style="text-align: center;">Welcome to the TinyMCE editor demo!</h2>
  <p>
    Please try out the features provided in this example. Check out the next paragraph's HTML.
    You'll see html tags not rendered in the editor's WYSIWYG output. Next, play with the
    Codepen JS to see what you can change in the editor.
