title: Strict DocType imposes minimum table row height in FF/Chrome
body: <p>Something i'd never noticed before, but it seems that in Chrome/Firefox (and probably Opera/Safari, i've not checked those specifically) using a strict doctype prevents table rows from being displayed smaller than a value that i'm unable to determine the calculation of.</p>
  
  <p>The following document displays as one might imagine in IE7 with all table rows around 8px in height to match the height of the content (which is probably incorrect knowing IE), whilst in Chome/Firefox the rows are all 23px tall. No combination of border-collapse, padding, margin etc i've found will allow the rows to be smaller than this.</p>
  
  <pre><code>    &lt;!DOCTYPE html PUBLIC "-//W3C//DTD Xhtml 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt;

      span {
        font-family: Verdana;
        font-size: 8px;
        line-height: 8px;
      }
    &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;table cellspacing="1" border="1"&gt;
      &lt;tr&gt;
        &lt;td&gt;&lt;span&gt;One&lt;/span&gt;&lt;/td&gt;
        &lt;td&gt;&lt;span&gt;Two&lt;/span&gt;&lt;/td&gt;
        &lt;td&gt;&lt;span&gt;Three&lt;/span&gt;&lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr&gt;
        &lt;td&gt;&lt;span&gt;Four&lt;/span&gt;&lt;/td&gt;
        &lt;td&gt;&lt;span&gt;Five&lt;/span&gt;&lt;/td&gt;
        &lt;td&gt;&lt;span&gt;Six&lt;/span&gt;&lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr&gt;
        &lt;td&gt;&lt;span&gt;Seven&lt;/span&gt;&lt;/td&gt;
        &lt;td&gt;&lt;span&gt;Eight&lt;/span&gt;&lt;/td&gt;
        &lt;td&gt;&lt;span&gt;Nine&lt;/span&gt;&lt;/td&gt;
      &lt;/tr&gt;
    &lt;/table&gt;  
  &lt;/body&gt;
  &lt;/html&gt;

  <p>Setting the doctype to transitional causes the table rows to display around 8px in height as expected.</p>
  
  <p>Does anyone have any idea what's causing this apparent minimum row height?</p>
  
  <p>Cheers for any info.</p>
