Markup
A markup may refer to any of the following:
1. With a word processor and other text editors, markup are comments and tracked changes that help keep track of changes made to documents being modified by multiple people.
How to enable markup in Microsoft Word
You can enable and disable what markup is shown in Microsoft Word by clicking the Review tab and selecting the "Show Markup" option and check or uncheck the markup you want to view.
Under Balloons, you can view the markup in balloons on the edge of the document or inline.
If you have a lot of different reviewers, click Reviewers and select only the reviewers that interest you.
If a document is marked as final, editing and markup is not visible.
2. Markup is a code, name, or tag used to define the layout or style of how a text is displayed. For example, with HTML (hypertext markup language) that creates web pages on the Internet the <b></b> tag (markup) bolds text on a page. See our markup language page for a full definition of markup languages and examples of other markup languages.
3. When dealing with a price or money, a markup is an increase in price from the original retail cost. The higher the mark up the more money (margin) the retailer makes when selling each unit with a mark up.
