Further on that note, this is a header for a section that has no additional content... so it already shouldn't be a section but this especially shouldn't be a header. A header element should contain introductory content relevant to its nearest ancestral sectioning element (a section, article, aside, etc.) or if its nearest sectioning ancestor is the body it acts as a header for the entire document).

This instance also contains only text, not a heading or other semantically meaningful element.

This whole thing should probably be wrapped in an article element with one heading. I'd probably wrap that in a main as well:

<pre><code>&lt;main role="main"&gt;>
  &lt;article&gt;
    &lt;h1 class="center"&gt;{{ _('Apply') }}&lt;/h1&gt;
</code></pre>
