So I guess, in essence the answer is NO you cannot begin a class or
ID name with numeric characters?
The answer is no. Isn't the css2.1 spec clear enough ?

This is not correct. You can begin ID and class selectors with numbers.
The only thing is that they must be encoded properly with characters
escapes (the above spec gives details).

It would be very wise for every one to study the source code showing CSS
and HTML. IE9, FF3.6.16 and Opera 11 parses this correctly. WebKit fails
with the blue border.
This is the CSS.
#\31\31\31\31 { background: lime }
equals #1111 { background: lime }
.\32\32\32\32 { background: #\0030\0066\0030 }
equals .2222 { background: lime }
.\06B0 { background: lime }
equals .ڰ { background: lime }
\0064\0069\0076 { bac\k\g\r\o\u\nd: lime; border: 10\0070\x solid
\0062\006C\0075\0065 }
equals div { background: lime; border: 10px solid blue }
Character escapes play an impotent role is CSS tokenization (I'm still
learning).
