Heading elements implement six levels of document headings,
<h1> is the most important and
<h6> is the least. A
heading element briefly describes the topic of the section it introduces. Heading information may be used by user agents, for example, to construct a
table of contents for a document automatically.
The HTML Strong Element (
<strong>) gives text strong importance, and is typically displayed in bold.
<progress> Element is used to view the completion progress of a task. While the specifics of how it's displayed is left up
The HTML Subscript Element (
<sub>) defines a span of text that should be displayed, for typographic reasons, lower, and often
smaller, than the main span of text.
<keygen> element exists to facilitate generation of key material, and submission of the public key as part of an HTML form.
This mechanism is designed for use with Web-based certificate management systems. It is expected that the
<keygen> element will be
used in an HTML form along with other information needed to construct a certificate request, and that the result of the process will be a signed
<figcaption> element represents a caption or a legend associated with a figure or an illustration described by the rest of
the data of the
<figure> element which is its immediate ancestor which means
<figcaption> can be the first or last
element inside a
<figure> block. Also, the HTML Figcaption Element is optional; if not provided, then the parent figure element will
have no caption.
<p> element (or HTML Paragraph Element) represents a paragraph of text.
<bdi> Element (or Bi-Directional Isolation Element) isolates a span of text that might be formatted in a different
direction from other text outside it.
<data> Element links a given content with a machine-readable translation. If the content is time- or date-related, the
<time> must be used.
The HTML Mark Element (
<mark>) represents highlighted text, i.e., a run of text marked for reference purpose, due to its relevance
in a particular context. For example it can be used in a page showing search results to highlight every instance of the searched-for word.
<ruby> Element represents a ruby annotation. Ruby annotations are for showing pronunciation of East Asian characters.
The HTML Superscript Element (
<sup>) defines a span of text that should be displayed, for typographic reasons, higher, and often
smaller, than the main span of text.
graphs, make photo compositions or even perform animations. You may (and should) provide alternate content inside the
The HTML Label Element (
<label>) represents a caption for an item in a user interface. It can be associated with a control either by
placing the control element inside the
<label> element, or by using the for attribute. Such a control is called the labeled control
of the label element. With one input can be assosiated few labels.
<section> element represents a generic section of a document, i.e., a thematic grouping of content, typically with a
<section> should be identified, typically by including a heading (
element) as a child of the
<figure> element represents self-contained content, frequently with a caption (
<figcaption>), and is
typically referenced as a single unit. While it is related to the main flow, its position is independent of the main flow. Usually this is an image, an
illustration, a diagram, a code snippet, or a schema that is referenced in the main text, but that can be moved to another page or to an appendix
without affecting the main flow.
<pre> element (or HTML Preformatted Text) represents preformatted text. Text within this element is typically displayed in
a non-proportional font exactly as it is laid out in the file. Whitespaces inside this element are displayed as typed.
<bdo> Element (or HTML bidirectional override element) is used to override the current directionality of text. It causes
the directionality of the characters to be ignored in favor of the specified directionality.
The HTML Definition Element (
<dfn>) represents the defining instance of a term.
The HTML Quote Element (
<q>) indicates that the enclosed text is a short inline quotation. This element is intended for short
quotations that don't require paragraph breaks; for long quotations use
The HTML Strikethrough Element (
<s>) renders text with a strikethrough, or a line through it. Use the
to represent things that are no longer relevant or no longer accurate. However,
<s> is not appropriate when indicating document
edits; for that, use the
<ins> elements, as appropriate.
<time> element represents either a time on a 24-hour clock or a precise date in the Gregorian calendar (with optional time
and timezone information).
<dialog> element represents a dialog box or other interactive component, such as an inspector or window.
<form> elements can be integrated within a dialog by specifying them with the attribute method="dialog". When such a form is
submitted, the dialog is closed with a returnValue attribute set to the value of the submit button used.
<dd> element (HTML Description Element) indicates the description of a term in a description list (
element. This element can occur only as a child element of a definition list and it must follow a
<hr> element represents a thematic break between paragraph-level elements (for example, a change of scene in a story, or a
shift of topic with a section). In previous versions of HTML, it represented a horizontal rule. It may still be displayed as a horizontal rule in visual
browsers, but is now defined in semantic terms, rather than presentational terms.
<ul> element (or HTML Unordered List Element) represents an unordered list of items, namely a collection of items that do
not have a numerical ordering, and their order in the list is meaningless. Typically, unordered-list items are displayed with a bullet, which can be of
several forms, like a dot, a circle or a squared. The bullet style is not defined in the HTML description of the page, but in its associated CSS, using
the list-style-type property.
The HTML element line break
<br> produces a line break in text (carriage-return). It is useful for writing a poem or an address,
where the division of lines is significant.
The HTML element emphasis
<em> marks text that has stress emphasis. The
<em> element can be nested, with each
level of nesting indicating a greater degree of emphasis.
<rp> element is used to provide fall-back parenthesis for browsers non-supporting ruby annotations. Ruby annotations are
for showing pronounciation of East Asian characters, like using Japanese furigana or Taiwainese bopomofo characters. The
is used in the case of lack of
<ruby> element support its content has what should be displayed in order to indicate the presence of a
ruby annotation, usually parentheses.
<samp> element is an element intended to identify sample output from a computer program. It is usually displayed in the
browser's default monotype font (such as Lucida Console).
The HTML Underline Element (
<u>) renders text with an underline, a line under the baseline of its content.
The HTML Table Body Element (
<tbody>) defines one or more
<tr> element data-rows to be the body of its parent
<table> element (as long as no
<tr> elements are immediate children of that table element.) In conjunction with a
<tbody> provides additional semantic information for
devices such as printers and displays. Of the parent table's child elements,
<tbody> represents the content which, when longer than a
page, will most likely differ for each page printed; while the content of
<tfoot> will be the same or
similar for each page printed. For displays,
<tbody> will enable separate scrolling of the
<caption> elements of the same parent
<table> element. Note that unlike the
<caption> elements however, multiple
<tbody> elements are permitted (if consecutive), allowing the data-rows
in long tables to be divided into different sections, each separately formatted as needed.
<article> element represents a self-contained composition in a document, page, application, or site, which is intended to
be independently distributable or reusable (e.g., in syndication). This could be a forum post, a magazine or newspaper article, a blog entry, an object,
or any other independent item of content. Each
<article> should be identified, typically by including a heading
<h6> element) as a child of the
<div> element (or HTML Document Division Element) is the generic container for flow content, which does not inherently
represent anything. It can be used to group elements for styling purposes (using the class or id attributes), or because they share attribute values,
such as lang. It should be used only when no other semantic element (such as
<nav>) is appropriate.
<li> element (or HTML List Item Element) is used to represent an item in a list. It must be contained in a parent element:
an ordered list (
<ol>), an unordered list (
<ul>), or a menu (
<menu>). In menus and unordered
lists, list items are usually displayed using bullet points. In ordered lists, they are usually displayed with an ascending counter on the left, such as
a number or letter.
<abbr> element (or HTML Abbreviation Element) represents an abbreviation and optionally provides a full description for it.
If present, the title attribute must contain this full description and nothing else.
The HTML Citation Element (
<cite>) represents a reference to a creative work. It must include the title of a work or a URL
reference, which may be in an abbreviated form according to the conventions used for the addition of citation metadata.
<i> Element represents a range of text that is set off from the normal text for some reason, for example, technical terms,
foreign language phrases, or fictional character thoughts. It is typically displayed in italic type.
<rt> Element embraces pronunciation of characters presented in a ruby annotations, which are used to describe the
pronunciation of East Asian characters. This element is always used inside a
The HTML Small Element (
<small>) makes the text font size one size smaller (for example, from large to medium, or from small to
x-small) down to the browser's minimum font size. In HTML5, this element is repurposed to represent side-comments and small print, including copyright
and legal text, independent of its styled presentation.
The HTML Variable Element (
<var>) represents a variable in a mathematical expression or a programming context.
<dl> element (or HTML Description List Element) encloses a list of pairs of terms and descriptions. Common uses for this
element are to implement a glossary or to display metadata (a list of key-value pairs).
<main> element represents the main content of the
<body> of a document or application. The main content
area consists of content that is directly related to, or expands upon the central topic of a document or the central functionality of an application.
This content should be unique to the document, excluding any content that is repeated across a set of documents such as sidebars, navigation links,
copyright information, site logos, and search forms (unless the document's main function is as a search form).
<b> Element represents a span of text stylistically different from normal text, without conveying any special importance or
relevance. It is typically used for keywords in a summary, product names in a review, or other spans of text whose typical presentation would be
boldfaced. Another example of its use is to mark the lead sentence of each paragraph of an article.
The HTML Code Element
<code> represents a fragment of computer code. By default, it is displayed in the browser's default monospace
The HTML Keyboard Input Element (
<kbd>) represents user input and produces an inline element displayed in the browser's default
<rtc> Element embraces semantic annotations of characters presented in a ruby of
<rb> elements used
<rb> elements can have both pronunciation (
<rt>) and semantic (
<span> element is a generic inline container for phrasing content, which does not inherently represent anything. It can be
used to group elements for styling purposes (using the class or id attributes), or because they share attribute values, such as lang. It should be used
only when no other semantic element is appropriate.
<span> is very much like a
<div> element, but
is a block-level element whereas a
<span> is an inline element.
The HTML element word break opportunity
<wbr> represents a position within text where the browser may optionally break a line,
though its line-breaking rules would not otherwise create a break at that location.
<dt> element (or HTML Definition Term Element) identifies a term in a definition list. This element can occur only as a
child element of a
<dl>. It is usually followed by a
<dd> element; however, multiple
elements in a row indicate several terms that are all defined by the immediate next
<ol> Element (or HTML Ordered List Element) represents an ordered list of items. Typically, ordered-list items are
displayed with a preceding numbering, which can be of any form, like numerals, letters or Romans numerals or even simple bullets. This numbered style is
not defined in the HTML description of the page, but in its associated CSS, using the list-style-type property.
<content> element is used inside of Shadow DOM as an insertion point. It is not intended to be used in ordinary HTML. It is
used with Web Components.
