<p>The placeholder for newly added content is hardcoded in <code>frontend_editing.js</code> right now.<br>
To allow styling of the placeholder it would be great if custom modules could override the element.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Introduce a theme function for the placeholder:</p>
<p><code class="js">Drupal.theme.frontendEditingPlaceholder</code></p>
