| Description | The Rich Text Format (often abbreviated RTF) is a proprietary document file format with published specification developed by Microsoft Corporation for cross-platform document interchange with Microsoft products. Most word processors are able to read and write some versions of RTF. | HyperText Markup Language, commonly referred to as HTML, is the standard markup language used to create web pages. Along with CSS, and JavaScript, HTML is a cornerstone technology, used by most websites to create visually engaging web pages, user interfaces for web applications, and user interfaces for many mobile applications. |
| Technical details | Unlike many word processing formats, RTF code can be human-readable: when an RTF file is viewed as a plain text file, the contained ASCII text is legible. The formatting code is not too distracting nor counter-intuitive, provided that the document's creator kept formatting concise. | HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. |
