    Inline boxes are inline-level boxes whose contents (child boxes) participate in the same inline formatting context
    as the box itself.

    An inline box initially creates an unsized open fragment, since its width depends on its children. The fragment is
    sized and placed later on, either when its line needs to be split or when its element is closed, which happens after
    all its children in the element tree have already been placed.
