[src]
fn is_empty(&self) -> bool
[src]
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
fn is_root(&self) -> bool
[src]
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
fn pseudo_element_originating_element(&self) -> Option<Self>
[src]

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