title: Blockquote element for centered text in books
body: <p>Once in a while, a novel (book, story, short story, etc.) will have a block of centered text to display something external from the main subject, either a sign that is being read, an abstract text, etc.</p>
  
  <p>Would it be proper (semantically correct) to use the <code>blockquote</code> element in these cases? For example:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>section {
    width: 350px;
    font: 14px/1.3em Charter, sans-serif;
    text-align: justify;
  }
  
  p {
    margin: 0;
  }
  
  section&gt;p+p {
    text-indent: 1.5em;
  }
  
  blockquote {
    text-align: center;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;section&gt;
    &lt;p&gt;I stepped back as far as I could and bent to peer under the door. There was nobody there; the stall must have been locked from the inside.&lt;/p&gt;
    &lt;p&gt;Cursing, I lowered my face and saw a piece of wet paper lying on the floor in front of the stall. It must’ve been glued to the door and fallen off. It informed:&lt;/p&gt;
    &lt;blockquote&gt;
      &lt;p&gt;Closed for maintenance.&lt;/p&gt;
      &lt;p&gt;Sorry for any inconvenience.&lt;/p&gt;
    &lt;/blockquote&gt;
    &lt;p&gt;I fixed my eyes on the space between the floor and the door. It wasn’t so small, maybe […]&lt;/p&gt;
  &lt;/section&gt;</code></pre>
  </div>
