I have an angular app. The main component is "<todo-app>" and it has two childs "<todolist>" and "<createTodo>". The html of the main app looks like this: <todolist /><createTodo />. I want to use css to reorder the components. So i give <createTodo> the order 1 and <todolist> the order 0. Now i need to make the parent (<todolist>) a flex display. How can i access the parent element in css ?
