The <datalist> element is used to define autocompletion values for an associated <input> element. Suggested autocompletion values are added to a datalist by nesting one or more <option> elements between the opening and closing <datalist> tags.
The <figure> element identifies self-contained content related to the main content, such as an image, table, or chart. The <figcaption> element is often nested within a <figure> element to add a caption to the content identified by the <figure> tags.
The <article> element identifies a self-contained piece of content which could theoretically be distributed to other websites and platforms as a stand-alone unit. The <article> element is a good choice to contain entire blog posts, news articles, and similar content.
The <footer> element is a structural element used to identify the footer of a page, document, article, or section. A <footer> typically contains copyright and authorship information or navigational elements pertaining to the contents of the parent element.
The <video> element, which adds native video playback support to the HTML specification in HTML5, can be used to embed a video in an HTML document. Add the video URL to the element by using either the src attribute of the <video> element or by nesting one or more <source> elements between the opening and closing <video> tags.
The <aside> element is used to identify content that is related to the primary content of the webpage, but does not constitute the primary content of the page. Author information, related links, related content, and advertisements are exampes of content that may be found in an aside element.
The <header> element is used to identify content that precedes the primary content of the web page and often contains website branding, navigation elements, search forms, and similar content that is duplicated across all or most pages of a website.
The <menu> element defines an instance of a menu. This experimental HTML feature has very limited browser support, but may soon be an effective way to add menu items to context menus and to create interactive web application menus.
The <s> element is used to identify text that is no longer accurate or relevant. It is similar to, but semantically distinct from, the <del> element which is used to identify document edits. By default, browsers render the contents of an <s> element with a strikethrough.
The <bdi> element is used to isolate a small section of text which may be formatted to run in the opposite direction than the text around it (such as right-to-left in a left-to-right context). This is useful when a language with right-to-left directionality, such as Arabic or Hebrew, is used inline with left-to-right languages.
