title: How do I use CSS to style Angular Material tabs?
body: <p>I am very new to Angular. 
  I recently added Angular Material tab in my app project similar to the one below. </p>
  
  <pre><code>&lt;mat-tab-group&gt;
    &lt;mat-tab label="First"  class="firstTab"&gt; Content 1 &lt;/mat-tab&gt;
    &lt;mat-tab label="Second" class="secondTab"&gt; Content 2 &lt;/mat-tab&gt;
    &lt;mat-tab label="Third"  class="thirdTab"&gt; Content 3 &lt;/mat-tab&gt;
  &lt;/mat-tab-group&gt;
  </code></pre>
  
  <p>In my app, I sometimes need to bring certain tabs to a user's attention. The approach I was thinking of, is by highlighting the tab of interest by giving it the below qualities:</p>
  
  <pre><code>.highLightTab{
     border-width: 9px;
     border-style: solid;
     border-color: orange;
  }
  </code></pre>
  
  <p><a href="https://i.stack.imgur.com/ge94C.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ge94C.png" alt="enter image description here"></a></p>
  
  <p>The traditional way to achieve the above would be through </p>
  
  <pre><code>$(".secondTab").addClass("highLightTab");
  </code></pre>
  
  <p>However, this is proving impossible to achieve as am not able to customized CSS classes/CSS styling to any of the Mat-X elements that are generated during runtime.</p>
  
  <p>Can anyone kindly tell me how to achieve this?</p>
