This trait allows to define the parser implementation in regards of pseudo-classes/elements

Associated Types

non tree-structural pseudo-classes (see: https://drafts.csswg.org/selectors/#structural-pseudos)

pseudo-elements

Provided Methods

Declares if the following "attribute exists" selector is considered "common" enough to be shareable. If that's not the case, when matching over an element, the relation AFFECTED_BY_NON_COMMON_STYLE_AFFECTING_ATTRIBUTE would be set.

Declares if the following "equals" attribute selector is considered "common" enough to be shareable.
