The majority of HTML and XHTML elements are nonreplaced elements, which means their content is presented by the user agent inside a box generated by the element itself. For example,
<span>hi there</span> is a nonreplaced element, and the text
hi there will be displayed by the user agent. Paragraphs, headings, table cells, lists, and almost everything else in HTML and XHTML are nonreplaced elements.
