title: WPF Button Trigger change child Textblock Foreground XAML
body: <p>I have this button in XAML:</p>
  
  <pre><code>&lt;Button Style="{StaticResource HeadButton}"&gt;
      &lt;TextBlock Style="{StaticResource HeadButtonText}"&gt;Add flavor&lt;/TextBlock&gt;
  &lt;/Button&gt;
  </code></pre>
  
  <p>And I need that when you hover over the button, the <code>TextBlock</code> Foreground property should change (I know I can use Content in the button but I'm doing it like this for another reason).</p>
  
  <p>How can I achieve this?</p>
