title: CSS force "font-size: small;" to 13px
body: <p>how can I force the attribute "small" to a specifically size? (ex: 13px)</p>
  
  <p>I'm reading data from a db and I have to display tags like this:</p>
  
  <pre><code>&lt;p class="MsoNormal" style="margin: 0cm 0cm 0pt; text-align: justify;"&gt;&lt;span style="font-size: small;"&gt;Text&lt;/span&gt;&lt;/p&gt;
  </code></pre>
  
  <p>I can't modify these tags and  works different in IE8 and FireFox so I want to force it.</p>
  
  <p>Is it possible? </p>
  
  <p>Thank you. </p>
