The HTML5 <article> element represents a complete composition in a web page or web application that is independently distributable or reusable, e.g. in syndication. This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content.
The role attribute is used to define an element's role on a page. When sectioning elements were introduced, the role attribute became used less for landmarking. This is because roles were applied by default to most sectioning elements, therefore, they were more widely used and accepted for their simplicity.
A description list (a.k.a. association list or definition list) consists of name–value groups, [21] and was known as a definition list prior to HTML5. [22] Description lists are intended for groups of "terms and definitions, metadata topics and values, questions and answers, or any other groups of name–value data". [23]
In the HTML code for each section there is an "id" attribute holding the section title. This enables linking directly to sections. These section anchors are automatically used by MediaWiki when it generates a table of contents for the page, and therefore when a section heading in the ToC is clicked, it will jump to the section.
The fragment contains a fragment identifier providing direction to a secondary resource, such as a section heading in an article identified by the remainder of the URI. When the primary resource is an HTML document, the fragment is often an id attribute of a specific element, and web browsers will scroll this element into view.
Semantic HTML is a way of writing HTML that emphasizes the meaning of the encoded information over its presentation (look). HTML has included semantic markup from its inception, [85] but has also included presentational markup, such as < font >, < i > and < center > tags. There are also the semantically neutral div and span tags.
In many Wiki markup languages, the semantics and effect of HTML <blockquote> is different from the use of an initial colon in a paragraph, which may be translated into an HTML dd element enclosed within a dl element. (That is a "data definition" within a "definition list", without there being any preceding "data term" or dt element).
In HTML and XML, a numeric character reference refers to a character by its Universal Character Set/Unicode code point, and uses the format: &#xhhhh;. or &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.
