About formatting

print start_form(-action=>'index.pl');
print p( {-align=>'center'}, span( {class=>'tip'}, "ÄéÜëåîå Ýíá áðü ôá êåßìåíá ãéá íá äéáâÜóåéò => " ),
popup_menu( -name=>'select', -values=>\@display_files ),
submit('ÅðéëïãÞ'));
print end_form;


This is non-Perl question but i really must understand why its not working:

inside styles.css i have:

td.tip {
 	font: 18px times;
	color: cyan;
}

But i cant see thes quotes text in "big centered lime colored text"

Sorry for asking this. I googles but i got general stuff not answer to this specific question.
