Copyright Goodheart-Willcox Co., Inc. Chapter 1 Introduction to Information Technology 21 HTML Hypertext markup language (HTML) is a language used to create documents that tell browsers how to assemble text, images, and other content to display as a web page. The basis of HTML is tags, which are codes that let the browser know how to display a document. Figure 1-16 shows a basic web page and the HTML used to create it. HTML provides for basic formatting for a document. A cascading style sheet (CSS) provides defi nitions that control the formatting of HTML documents and other markup documents. It has become the standard for how to control the appearance of a website. Users can create HTML pages directly in Microsoft Word by resaving the fi le as a web page fi le type. This fi le type will open in the user’s default web browser. Once saved, the user can view the plain text version of the fi le without HTML markup by right-clicking the fi le and choosing Open with Notepad. GS5 Key Applications 1.2 !
