Associated Types

Required Methods

Converts self into an opaque representation.

Skips non-element nodes

Skips non-element nodes

Skips non-element nodes

Skips non-element nodes

Empty string for no namespace

Whether this element is a link.

Returns whether this element matches :empty.

That is, whether it does not contain any child element or any non-zero-length text node. See http://dev.w3.org/csswg/selectors-3/#empty-pseudo

Returns whether this element matches :root, i.e. whether it is the root element of a document.

Note: this can be false even if .parent_element() is None if the parent node is a DocumentFragment.

Provided Methods

The parent of a given pseudo-element, after matching a pseudo-element selector.

This is guaranteed to be called in a pseudo-element.

Returns the assigned element this element is assigned to.

Necessary for the ::slotted pseudo-class.

Returns whether this element should ignore matching nth child selector.

Return true if we want to stop lookup ancestor of the current element while matching complex selectors with descendant/child combinator.
