The <div> element is used to organize subsets of content into
logical groups that are not intended to be or should not be contained as a topic.
The <div> element is designed to be a grouping element; it does not
imply any explicit semantics or contain an explicit title. This avoids enabling the creation
of deeply-nested content that would otherwise be written as separate topics. If the content requires a title, use a
<section> element, a nested <topic>, or
possibly a <fig> element.
