// TODO: add tests for ID with accordance to CSS spec:
//
// From https://drafts.csswg.org/selectors/#id-selectors:
//
// > An ID selector consists of a “number sign” (U+0023, #) immediately followed by the ID value, which must be a CSS identifier.
//
// From: https://www.w3.org/TR/CSS21/syndata.html#value-def-identifier:
//
// > 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.
// > 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".
// > Note that Unicode is code-by-code equivalent to ISO 10646 (see [UNICODE] and [ISO10646]).

// TODO: add tests for class with accordance to CSS spec:
