The <a> HTML element (or anchor element), with its href attribute, creates a hyperlink to web pages, files, email addresses, locations in the same page, or anything else a URL can address.
The <article> HTML 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). Examples include: a forum post, a magazine or newspaper article, or a blog entry, a product card, a user-submitted comment, an interactive widget or gadget, or any other independent item of content.
The <aside> HTML element represents a portion of a document whose content is
only indirectly related to the document's main content. Asides are frequently presented as sidebars or call-out boxes.
The <blockquote> HTML element indicates that the enclosed text is an extended quotation. Usually, this is rendered visually by indentation. A URL for the source of the quotation may be given using the cite attribute, while a text representation of the source can be given using the <cite> element.
The <col> HTML element defines one or more columns in a column group represented by its parent <colgroup> element. The <col> element is only valid as a child of a <colgroup> element that has no span attribute defined.
The <details> HTML element creates a disclosure widget in which information is visible only when the widget is toggled into an "open" state. A summary or label must be provided using the <summary> element.
The <div> HTML element is the generic container for flow content. It has no effect on the content or layout until styled in some way using CSS (e.g. styling is directly applied to it, or some kind of layout model like Flexbox is applied to its parent element).
The <dl> HTML element represents a description list. The element encloses a list of groups of terms (specified using the <dt> element) and descriptions (provided by <dd> elements). Common uses for this element are to implement a glossary or to display metadata (a list of key-value pairs).
The <dt> HTML element specifies a term in a description or definition list, and as such must be used inside a <dl> element. It is usually followed by a <dd> element; however, multiple <dt> elements in a row indicate several terms that are all defined by the immediate next <dd> element.
The HTML element embeds external content at the specified point in the document. This content is provided by an external application or other source of interactive content such as a browser plug-in.
The <footer> HTML element represents a footer for its nearest ancestor sectioning content or sectioning root element. A footer typically contains information about the author of the section, copyright data or links to related documents.
The <h1> HTML element represents a level 1 heading. It is used to define the most important heading on the page, typically used for the main title or topic of the content.
The <h2> HTML element represents a level 2 heading. It is used to define subheadings or secondary titles within a document, providing a hierarchical structure to the content.
The <h3> HTML element represents a level 3 heading. It is used to define subheadings or tertiary titles within a document, providing further hierarchical structure to the content.
The <h4> HTML element represents a level 4 heading. It is used to define subheadings or quaternary titles within a document, providing additional hierarchical structure to the content.
The <h5> HTML element represents a level 5 heading. It
is used to define subheadings or quinary titles within a document, providing further hierarchical structure to the content.
The <h6> HTML element represents a level 6 heading. It is used to define subheadings or senary titles within a document, providing the lowest level of hierarchical structure to the content.
The <header> HTML element represents introductory content, typically a group of introductory
or navigational aids. It may contain some heading elements but also a logo, a search form, an author name, and other elements.
The <hr> HTML element represents a thematic break between paragraph-level elements: for example, a change of scene in a story, or a shift of topic within a section.
The <html> HTML element represents the root (top-level element) of an HTML document, so it is also referred to as the root element. All other elements must be descendants of this element.
The HTML element is used to create interactive controls for web-based forms in order to accept data from the user; a wide variety of types of input data and control widgets are available, depending on the device and user agent.
The <li> HTML 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.
The <link> HTML element specifies relationships between the current document and an external resource. This element is most commonly used to link to stylesheets, but is also used to establish site icons (both "favicon" style icons and icons for the home screen and apps on mobile devices) among other things.
The <main> HTML element represents the dominant content of the <body> of a document. 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.
The <meta> HTML element represents metadata that cannot be represented by other HTML meta-related elements, like <base>, <link>, <script>, <style> or <title>.
The <nav> HTML element represents a section of a page whose purpose is to provide navigation links, either within the current document or to other documents. Common examples of navigation sections are menus, tables of contents, and indexes.
The <p> HTML element represents a paragraph. Paragraphs are usually represented in visual media as blocks of text separated from adjacent blocks by blank lines and/or first-line indentation, but HTML paragraphs can be any structural grouping of related content, such as images or form fields.
The <polyline> SVG element is an SVG basic shape that creates straight lines connecting several points. Typically a polyline is used to create open shapes as the last point doesn't have to be connected to the first point.
The <pre> HTML element represents preformatted text which is to be presented exactly as written in the HTML file. The text is typically rendered using a non-proportional, or monospaced, font. Whitespace inside this element is displayed as written.
The <rect> element is a basic SVG shape that draws rectangles, defined by their position, width, and height. The rectangles may have their corners rounded.
The <script> HTML element is used to embed executable code or data; this is typically used to embed or refer to JavaScript code. The <script> element can also be used with other languages, such as WebGL's GLSL shader programming language and JSON.
The <section> HTML element represents a generic standalone section of a document, which doesn't have a more specific semantic element to represent it. Sections should always have a heading, with very few exceptions.
The <summary> HTML element specifies a summary, caption, or legend for a <details> element's disclosure box. Clicking the <summary> element toggles the state of the parent <details> element open and closed.
The <svg> element is a container that defines a new coordinate system and viewport. It is used as the outermost element of SVG documents, but it can also be used to embed an SVG fragment inside an SVG or HTML document.
The <table> HTML element represents tabular data—that is, information presented in a two-dimensional table comprised of rows and columns of cells containing data.
The <tfoot> HTML element encapsulates a set of table rows (<tr> elements), indicating that they comprise the foot of a table with information about the table's columns. This is usually a summary of the columns, e.g., a sum of the given numbers in a column.
The <th> HTML element defines a cell as the header of a group of table cells and may be used as a child of the <tr> element. The exact nature of this group is defined by the scope and headers attributes.
The <thead> HTML element encapsulates a set of table rows (<tr> elements), indicating that they comprise the head of a table with information about the table's columns. This is usually in the form of column headers (<th> elements).
The <tr> HTML element defines a row of cells in a table. The row's cells can then be established using a mix of <td> (data cell) and <th> (header cell) elements.
