Markup 2 HTML Markup HTML tags are used to markup the structure of a document, and embed basic formatting information that the browser can use to decide how to display the content. Tags are constructed of brackets between which the tag is placed. Tags are placed around segments of text, so there is usually a companion end tag which is identical to the start tag except it includes a forward slash. These are used to include international characters as well as characters usually included in tags as markup.
Entities start with an ampersand, followed by the entity name and end with a semicolon.
