Represents a section of a page that consists of a composition that forms an independent part of a document, page, or site. This could be a forum post, a magazine or newspaper article, a Web log entry, a user-submitted comment, or any other independent item of content.
body element represents the main content of the document.
Represents an integration point for an external(typically non-
HTML) application or interactive content.
src attribute specifies the URL of the resource being embedded.
The optional type attribute specifies the
MIME type of the plugin to instantiate. The value must be a valid
MIME type, optionally with parameters. If both the type attribute and the src attribute are present, then the type attribute must specify the same
MIME type as the explicit Content-Type metadata of the resource given by the src attribute.
figure element represents some flow content, optionally with a caption, that is self-contained and is typically referenced as a single unit from the main flow of the document.
figure element can be used to annotate illustrations, diagrams, photos, code listings, etc., that are referenced in the main content of the document, but that could, without affecting the flow of the document, be moved away from that primary content â€” e.g., to the side of the page, to dedicated pages, or to an appendix.
Represents a span of text in an alternate voice or mood, or otherwise offset from the normal prose, such as a taxonomic designation, a technical term, an idiomatic phrase from another language, a thought, a ship name, or some other prose whose typical typographic presentation is italicized.
i when nothing more suitable is available â€” e.g.,
em for text with stress emphasis,
strong for text with semantic importance,
cite for titles in a citation or bibliography,
dfn for defining a word, and
var for mathematical variables.
img element represents an image. The image given by the
src attribute is the embedded content, and the value of the
alt attribute is the
img element's fallback content.
src attribute must be present, and must contain a valid non-empty URL potentially surrounded by spaces referencing a non-interactive, optionally animated, image resource that is neither paged nor scripted.
img element must not be used as a layout tool. In particular,
img elements should not be used to display transparent images, as they rarely convey meaning and rarely add anything useful to the document.
kbd element represents user input (typically keyboard input, although it may also be used to represent other input, such as voice commands).
kbd element is nested inside a
samp element, it represents the input as it was echoed by the system. When the
kbd element contains a
samp element, it represents input based on system output, for example invoking a menu item.
kbd element is nested inside another
kbd element, it represents an actual key or other single unit of input as appropriate for the input mechanism.
meter binding applies to a
meter element, the element is expected to render as an 'inline-block' box with a 'height' of '1em' and a 'width' of '5em', a 'vertical-align' of '-0.2em', and with its contents depicting a gauge.
When the element is wider than it is tall(or square), the depiction is expected to be of a horizontal gauge, with the minimum value on the right if the 'direction' property on this element has a computed value of '
rtl', and on the left otherwise. When the element is taller than it is wide, it is expected to depict a vertical gauge, with the minimum value on the bottom.
tbody element represents a block of rows that consist of a body of data for the parent table element, if the
tbody element has a parent and it is a table.
textarea element represents a multiline plain text edit control for the element's raw value. The contents of the control represent the control's default value.
