An sp-split-view element delivers its first two direct child elements in a horizontal or vertical (<sp-split-view vertical>) orientation that distributes the available page real estate as per the supplied attribute API. When leveraging the resizable attribute a pointer and keyboard accessible affordance is provided for the user to customize the distribution of that area between the available children.

Lorem Ipsum is simply dummy text of the printing and typesetting

ever since the 1500s, when an unknown printer took a galley of type
and scrambled it to make a type specimen book.
