A section may refer to any of the following:
1. In typography, a section is a distinct area of a document that is separated from other areas of the same object. A good example of a section is a chapter, usually distinguished by a title page. Sections may be marked by a solid or dotted line, highlighting, or some other means.
2. When referring to HTML, a section is an area in the web page containing specific programming, text, or images that are separated from other areas by using certain HTML tags. Common tags used to create sections in a web page are <div>, <frameset> and <section>. All web pages also have a <header> and <body> tag, which can be considered sections as well.
