68119 - CSS fails if underscore in class-name

Status: VERIFIED INVALID

(Core :: CSS Parsing and Computation, defect)

Description

[Raphael Bosshard]

When a class-name contains an underscore, like _test or test_test, mozilla
ignores the css-style for this class.

I took a look at the css-specs http://www.w3.org/Style/CSS/, but did't find
anything on how to name classes.

Underscores are _not_ allowed in class names according to the W3 spec
(underscore is ISO646 char code 95), see below. I don't have permission to mark
this as invalid though, please can someone do this for me.

From the www.w3.org site
*  In CSS2, identifiers  (including element names, classes, and IDs in
selectors) can contain only the characters [A-Za-z0-9] and ISO 10646 characters
161 and higher, plus the hyphen (-); they cannot start with a hyphen or a digit.
They can also contain escaped characters and any ISO 10646 character as a
numeric code (see next item). For instance, the identifier "B&W?" may be written
as "B\&W\?" or "B\26 W\3F".

Thanks for finding the relevant specs in the w3c site jungle, Bruce :-)
Once you have correctly triaged three bugs, like this one, please send me mail
and I'll give you the ability to edit the bugs directly :-)
Thanks,
Fabian.
