What is a markup language?
A markup language combines text and extra information about the text. The extra information, for example about the text’s structure or presentation, is expressed using markup, which is intermingled with the primary text.
The term “markup” is derived from the traditional publishing practice of “marking up” a manuscript, which is, adding symbolic printer’s instructions in the margins of a paper manuscript. markup Language indicate what typeface, style, and size should be applied to each part of a manuscript or data.
