Strict DocType Imposes Minimum Table Row Height In FF/Chrome

Post a Comment
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

Solution 1:

You need to set the line-height on the <td> aswell as the <span>

td{line-height:8px;}

Solution 2:

Heres a better explination:

View the code below in your browser.

Notice that even though we've set the font-size of the second set of <span> tags the actual table cells are the same size.

This is because the font size of the table cells IS still the same. We've only changed a child element of them, ie the <span>

setting body{font-size:8px} would work fine as the table will inherit this value. You can also use it directly on the table ie table{font-size:8px}, or you can use it on the cell as posted above.

<!DOCTYPE html PUBLIC "-//W3C//DTD Xhtml 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<head>
  <style>
    body{}
    td{}
    span {font-family: Verdana;}

    span.small{font-size:8px;}
  </style>
</head>
<body>
<h1>Default font size</h1>
  <table cellspacing="1" border="1" cellpadding="0">
    <tbody>
        <tr>
          <td><span>One</span></td>
          <td><span>Two</span></td>
          <td><span>Three</span></td>
        </tr>
        <tr>
          <td><span>Four</span></td>
          <td><span>Five</span></td>
          <td><span>Six</span></td>
        </tr>
        <tr>
          <td><span>Seven</span></td>
          <td><span>Eight</span></td>
          <td><span>Nine</span></td>
        </tr>
    </tbody>
  </table>  

  <h2>8px font size</h2>
   <table cellspacing="1" border="1" cellpadding="0">
    <tbody>
        <tr>
          <td><span class="small">One</span></td>
          <td><span class="small">Two</span></td>
          <td><span class="small">Three</span></td>
        </tr>
        <tr>
          <td><span class="small">Four</span></td>
          <td><span class="small">Five</span></td>
          <td><span class="small">Six</span></td>
        </tr>
        <tr>
          <td><span class="small">Seven</span></td>
          <td><span class="small">Eight</span></td>
          <td><span class="small">Nine</span></td>
        </tr>
    </tbody>
  </table>

</body>
</html>

Hope this helps
