Rich text

Rich text, as opposed to plain text, has styling information beyond the minimum of semantic elements: colours, styles (boldface, italic), sizes, and special features in HTML (such as hyperlinks). It is any text representation containing plain text completed by information such as a language identifier, font size, color, or hypertext links. Whereas plain text can be edited in any text editor, rich text depends on specific software, which often saves it in a binary format readable only by a limited number of software packages.

Rich text files are often edited through a WYSIWYG graphic user interface, whereby users utilise graphic representations of tools to manipulate the layout in programs such as Adobe's InDesign.
