fn main() {
let mut node = Node::new();
let mut child = Node::new();
let mut other_child = Node::new();
node.insert_child(&mut child, 0);
node.insert_child(&mut other_child, 1);
style!(node,
Margin(10 pt),
MarginLeft(Auto),
PaddingHorizontal(4 pt),
Left(16 %),
Bottom(UndefinedValue)
);
let child_styles = make_styles!(
