Does CSS script affect HTML tags inside php?

[NCC1701]

I have a table like this:

echo "<table border=\"1\" align=\"center\" width=\"50%\">";
 echo "<tr><td><strong>Nickname:</strong></td><td>".$row['nickname']."</td></tr>";
echo "</table>";

and i need some of the <td> tags to be formatted in a certain way, rather than adding the colour to each of the tags can i use css to format the colour etc of the tag? ive tried it and it seems to ignore the css scripting, can anyone tell me why or how i can rectify this?
