Content grouping elements
Inside a particular section of content on the page, the various components of that section
are broken into paragraphs, lists, figures, and the like. The elements for paragraphs and
so forth group content into smaller units than sections do. Except for figure and fig-
caption —which are new in HTML5—the elements in this group are all likely quite
familiar to you. See Table 2-8 for the content model categories and descriptions of these
elements.
