Provided Methods
fn attr_exists_selector_is_shareable(_attr_selector: &AttrSelector<Self>) -> bool
fn attr_equals_selector_is_shareable(_attr_selector: &AttrSelector<Self>, _value: &Self::AttrValue) -> bool
fn parse_non_ts_pseudo_class(_context: &ParserContext<Self>, _name: &str) -> Result<Self::NonTSPseudoClass, ()>
This function can return an "Err" pseudo-element in order to support CSS2.1 pseudo-elements.
