This is an excerpt of the grammar of CSS2:
-----------------------------------------------------------------
selector
: simple_selector [ combinator simple_selector ]*
;
simple_selector
: element_name? [ HASH | class | attrib | pseudo ]* S*
;
class
: '.' IDENT
;
element_name
: IDENT | '*'
;
.
.
.
nmstart [a-z]|{nonascii}|{escape}
nmchar [a-z0-9-]|{nonascii}|{escape}
string1 \"([\t !#$%&(-~]|\\{nl}|\'|{nonascii}|{escape})*\"
string2 \'([\t !#$%&(-~]|\\{nl}|\"|{nonascii}|{escape})*\'
ident {nmstart}{nmchar}*
.
.
.
{ident} {return IDENT;}
------------------------------------------------------------------
You can notice that IDENT cannot contain a '_' unless this character is
escaped.
The answer is therefore: escape the underscore. Example: instead of
writing foo_bar in the CSS, write foo\_bar.
