Element
查看源码part.Child(content).Style(style)Every part returns a fluent element. Strings, numbers, elements, and deferred child factories compose directly.
ChildChild(child any) *Element—
Child appends content and returns this element. Content can be an element, native node, scalar, accessor, or node-returning construction callback.
Child(child any) *Element查看源码ChildrenChildren(children ...any) *Element—
Children appends multiple children in order without replacing existing content. It also accepts []any, []*Element, and []*native.Node slices as arguments. Read the retained child nodes through element.Node.Children.

Style merges a reusable style. Scalar accessors retain independent native bindings.
