What are the advantages and disadvantages of using CSS selectors like tr.odd and tr.even versus more specific class names like tr.foo td for styling HTML elements in PHP-generated content?

When styling HTML elements in PHP-generated content, using more specific class names like tr.foo td allows for greater control and customization over the styling of individual elements. On the other hand, using CSS selectors like tr.odd and tr.even can provide a more concise and efficient way to style elements based on their position within a table. Ultimately, the choice between the two approaches depends on the specific requirements of the styling and the level of flexibility needed. 

// Using specific class names for styling HTML elements in PHP-generated content
echo '<table>';
echo '<tr class="foo">';
echo '<td>Row 1 Column 1</td>';
echo '<td>Row 1 Column 2</td>';
echo '</tr>';
echo '<tr class="foo">';
echo '<td>Row 2 Column 1</td>';
echo '<td>Row 2 Column 2</td>';
echo '</tr>';
echo '</table>';
