title: How to set padding and margin to all children elements to 0
body: <p>Tried these two and they don't work. It seems something really simple but cannot find anything on this topic.</p>
  
  <p>CSS:</p>
  
  <pre><code>#element * { padding: 0; margin 0; }
  </code></pre>
  
  <p>jQuery:</p>
  
  <pre><code>$("#element").children("*").css("padding", "0");
  $("#element").children("*").css("margin", "0");
  </code></pre>
  
  <p>Thank you in advance.</p>
