Markup language are designed for the processing, definition and presentation of text. What language does is to specifie the code for formating, both the layout and the style, within a text file. A code is used yo specify the formatting, they are called tags. A very important example of a markup language is: HTLM
HTLM (Hyper Text Markup Language) is a language to specify the structure, using browser programs of World Wide Web (WWW), of documents for retrieval across the Internet. There are several types of markup elements used in HTLM:
- Structural markup: It always describes the purpose of a text. It doesn’t denote any specific rendering, but most Web browsers have standardized default styles for element formatting. Text may be further styled with CSS.
- Presentational markup: It describes the appearance of the text, without being interested in its functions. The majority of the presentational markup elements became deprecated under the HTML 4.0 specification, in favour of CSS style design.
- Hypertext markup: It makes parts of a document into different links to other documents. Now HTML has become XHTML. In this case, href attribute has to be with valid URL.
Finally, we have to take into account that HTML documents can be delivered with any computer file. However, the most common ones are by HTTP from web sites or e-mails.
