Quote from http://www.w3c.org/TR/CSS21/grammar.html :
"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 ".55ft"
a valid class, CSS2 requires the first digit to be escaped (".\35 5ft")"
