I don't expect you to have done much on the computer. A few of you need to work on your grammar. We may not cover this section explicitly, but it gives you some things to think about. HTML is the markup language used for the World Wide Web. Unlike a programming language, which describes algorithms, HTML is simply a markup language.
Markup languages describe data.
Some of the same questions come up as you consider how the computer might represent any document. For example, a typical word-processed document will have different margins, font, and justification at different parts of the document. In logical markup , you indicate the role of each piece of text. In physical markup , you indicate the appearance of each piece of text. Different people have different expectations about the appearance of certain logical items Physical appearance does not necessarily indicate the logical role, even when the author of a document may intend you to do so.
