Overwrite add/edit form What I would like to do is to have a ?.tpl.php file in which I can write my own HTML content. A minimal example would be:

&lt;div class="my-class"&gt;
      &lt;?php drupal_render($input_label); ?&gt;
      &lt;br /&gt;
      &lt;?php drupal_render($input_text); ?&gt;
&lt;/div&gt;
As far as I know, path templates are built-in Drupal 7, so just do this:

page--node--add--blog.tpl.php (for blog)
page--node--add--story.tpl.php (for story)
etc.
etc.
