Why doesn't CSS hover work on table rows when the cells inside the rows have class names?

I am stuck with this problem so any help would be appreciated. I have a table with several rows. Each cell within the row belongs to a certain class. I use these class names to colour the cells.

Here is one example row from my table:

<tr>
     <td class = "summarypage-odd-column">Theme</td>    <td class = "summarypage-odd-column">Q2 2009</td>   <td class = "summarypage-odd-column">Q1 2009</td>
     <td class = "summarypage-even-column">Theme</td>   <td class = "summarypage-even-column">Q2 2009</td>  <td class = "summarypage-even-column">Q1 2009</td>
     <td class = "summarypage-odd-column">Business Area</td>    <td class = "summarypage-odd-column">Q1 2009</td>   <td class = "summarypage-odd-column">Q1 2008</td>
 </tr>

I would like to highlight each row when the user moves mouse pointer over any cell in that row. So I used the following CSS code to achieve that.

tr:hover {
  background-color: #FFFAF0; color: #000;
}

unfortunately it seems because each table data cell has a class name, the hover does not work. But if I remove the class names from data cells, the hover works.

My question is is there any way I can get the hover thing working for the table row, while still having class names for the table data cells inside the row.

Try this:

tr:hover td {
  background-color: #FFFAF0; color: #000;
}

Place this after the existing td style declarations to be safe

This does not happen for me. Make sure that you're only adding/removing class names when checking if they have an impact, and make sure that the tds don't have their own background covering up that of the tr.

You probably need to use the !important designator to make sure that your hover style overrides the background defined int he class:

tr:hover { 
    background-color: #FFFFAF0 !important;
    color: #000 !important; 
}

Interestingly, this won't work for IE6 because that browser only applies hover to a tags.

The CSS instructions within the classname takes precedence over the <tr> instructions.

To fix this, use td.summarypage-odd-column:hover, td.summarypage-even-column:hover inside your CSS.

Note: If you're using IE6, the :hover only works on links, i.e. a:hover.
