title: html setting width and height using style tag does not work
body: <p>I am trying to create a calendar with html and trying to set the width and height of each cell to 100. For this I tried using style tag as below. But for some reason, the height and width of each cell does not change. But instead of specifying the attributes in style tag, if I try to modify the individual cells with width/height attribute it works. Please help.</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
      &lt;style type="text/css"&gt;
      td {color:green; width:100; height:100}
      th {width:100}
      &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;table border="2"&gt;
   &lt;caption&gt; October 2012 Calendar&lt;/caption&gt;
    &lt;tr&gt;
      &lt;th&gt; Sunday &lt;/th&gt;
      &lt;th&gt; Monday &lt;/th&gt;
      &lt;th&gt; Tuesday &lt;/th&gt;
      &lt;th&gt; Wednesday &lt;/th&gt;
      &lt;th&gt; Thursday &lt;/th&gt;
      &lt;th&gt; Friday &lt;/th&gt;
      &lt;th&gt; Saturday &lt;/th&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
     &lt;td bgcolor="grey"&gt; &amp;nbsp; &lt;/td&gt;
     &lt;td&gt;1&lt;/td&gt;
     &lt;td&gt;2&lt;/td&gt;
     &lt;td&gt;3&lt;/td&gt;
     &lt;td background="../worldanimalday.jpg"&gt;4&lt;/td&gt;
     &lt;td&gt;5&lt;/td&gt;
     &lt;td&gt;6&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/table&gt;
  &lt;/body&gt;
  &lt;/html&gt;
