title: Add Style to Child of a td-Element
body: <p>In my table, the td-Elements contain sometimes a textarea, sometimes an input. 
  With a click on a td, I add the class 'active' to the element.</p>
  
  <pre><code>// Add Class to active cell
  $(function() {
      var table = $('table').on('click', 'td', function() {
        $('.table tr td').removeClass('active');
        $(this).addClass('active');
      });
  });
  </code></pre>
  
  <p>Now, I want to change the textalign of the inputs or the textareas.</p>
  
  <pre><code>$("#left_align_btn").click(function() {
       $('td.active').css('text-align', 'left');
  });
  </code></pre>
  
  <p>How can I achieve that the style will added to all the "Childs (sometimes an input, sometimes a textarea..." of the active td? </p>
  
  <p>Thank you</p>
