Block-level elements are page elements that consist of text laid out in paragraph-like forms. Block-level elements are

part of a document’s logical structure. Such elements are further classified as container elements, heading and

paragraph elements, label and list elements, special text elements, and table elements.

Container elements

Container elements are the highest level of element and provide hierarchical grouping for other block-level elements.

Document Document element. The root element of a document’s tag tree.

Part Part element. A large division of a document; may group smaller units of content together, such as division

elements, article elements, or section elements.

Div Division element. A generic block-level element or group of block-level elements.

Art Article element. A self-contained body of text considered to be a single narrative.

Sect Section element. A general container element type, comparable to Division (DIV Class=“Sect”) in HTML,

which is usually a component of a part element or an article element.

Heading and paragraph elements

Heading and paragraph elements are paragraph-like, block-level elements that include specific level heading and

generic paragraph (

P ) tags. A heading (H) element should appear as the first child of any higher-level division. Six

levels of headings (

H1 to H6) are available for applications that don’t hierarchically nest sections.

Label and list elements

Label and list elements are block-level elements used for structuring lists.

L List element. Any sequence of items of similar meaning or other relevance; immediate child elements should be

list item elements.

LI List item element. Any one member of a list; may have a label element (optional) and a list body element

(required) as a child.

LBL

Label element. A bullet, name, or number that identifies and distinguishes an element from others in the same list.

LBody List body element. The descriptive content of a list item.

Special text elements

Special text elements identify text that isn’t used as a generic paragraph (P).

BlockQuote Block quote element. One or more paragraphs of text attributed to someone other than the author of

the immediate surrounding text.

Caption Caption element. A brief portion of text that describes a table or a figure.

Index Index element. A sequence of entries that contain identifying text and reference elements that point out the

occurrence of the text in the main body of the document.

TOC Table of contents element. An element that contains a structured list of items and labels identifying those items;

has its own discrete hierarchy.
