title: right text align mat-expansion-panel material component
body: <p>I want to align the description text of <code>mat-expansion-panel</code> component to the right</p>
  
  <p>I have tried using align-text to right but nothing is changing
  Here's my HTML</p>
  
  <pre><code>&lt;mat-expansion-panel&gt;
      &lt;mat-expansion-panel-header&gt;
        &lt;mat-panel-title&gt;
          Cycle ingénieur en informatique
        &lt;/mat-panel-title&gt;
        &lt;mat-panel-description&gt;
          2014-2017
        &lt;/mat-panel-description&gt;
      &lt;/mat-expansion-panel-header&gt;
      ....
    &lt;/mat-expansion-panel&gt;
  </code></pre>
  
  <p>CSS :</p>
  
  <pre><code>mat-panel-description {
      text-align: right;
  }
  </code></pre>
  
  <p>Here's the actual behavior</p>

  <p>I would have that 2014-2017 stay stuck to the right.</p>
