Instance Method Details

#content_fragment ⇒ Object

A <template> element’s “template contents” - the separate DocumentFragment the HTML parser fills instead of making the parsed nodes children of the <template> (WHATWG DOM ‘HTMLTemplateElement.content`; browsers behave the same: template.children is empty, template.content holds the nodes). Lexbor stores it on the template interface; we surface it as a Makiri::DocumentFragment so it can be traversed/queried (`tpl.content_fragment.css(“p”)`).

Returns nil for any node that is not an HTML <template>. Note: CSS/XPath over the *template element itself* deliberately do NOT descend into the content (matching the DOM, and unavoidable for CSS since it runs Lexbor’s selector engine over the real tree) - query the fragment instead.
