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. 

Children(children ...any) *Element
查看源码
StyleStyle(style StyleBuilder) *Element—

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