title: p tag in button tag not allowed?
body: <p>I have a <code>&lt;button&gt;</code> element and within it, a <code>&lt;p&gt;</code> element. The <code>&lt;p&gt;</code> element is used in combination with css, <code>margin-top</code>, in a class to vertical align the text within the button (the button has a specific height).</p>
  
  <p>The html looks like this:</p>
  
  <pre><code>&lt;button class="someClass"&gt;
      &lt;img ... /&gt;
      &lt;p class="anotherClass"&gt;Caption&lt;/p&gt;
  &lt;/button&gt;
  </code></pre>
  
  <p>This works fine, the text is vertically aligned like it should be. However I get a warning inside visual studio 2012 saying: </p>
  
  <blockquote>
    <p>Element 'p' cannot be nested inside element 'button'.</p>
  </blockquote>

  <p><strong>My questions:</strong> why isn't the <code>&lt;p&gt;</code> element allowed inside a <code>&lt;button&gt;</code> element? And what is the alternative?</p>
