und dieses Dokument sagt über CSS identifiers:

In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, two hyphens, or a hyphen followed by a digit.

Hervorhebung von mir.

Eben deshalb muss die 4 ja escapet werden.

Wollen wir gemeinsam an jener Stelle weiterlesen?

Identifiers 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".
