problems with font color in Firefox/Chrome

.2f_subtext {
font-size: 11px;
color: #FFFFFF;

The font color is white in IE, there’s no problem, but in Firefox or Chrome, the font color is black.

W3C Css  validator :

In CSS1, a class name could start with a digit (“.55ft”), unless it was a dimension (“.55in”). In CSS2, such classes are parsed as unknown dimensions (to allow for future additions of new units) To make “2f_subtext” a valid class, CSS2 requires the first digit to be escaped “.\32 f_subtext” [2f_subtext]
