Copyright Goodheart-Willcox Co., Inc. 524 Unit 3 Living Online HTML and Web 2.0 Part of the problem of using documents stored on various computers around the world was solved by the URL and web servers. Once the document could be obtained, there remained the problem of how to open it and read its contents. HTML solved this problem. As the web has advanced, new capabilities have been introduced, giving rise to Web 2.0. 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. It allows a universal practice of marking up the documents for browsers. The basis of HTML is tags, which are codes that let the browser know how to display a document. Figure 13-10 shows a basic web page and the HTML used to create it. HTML provides for basic formatting for a document. A cascading style sheet provides advanced formatting and has become the standard for how to control the appearance of a website. A cascading style sheet (CSS) provides defi nitions that control the formatting of HTML documents and other markup documents. Interactive or dynamic pages require additional programming tools. JavaScript is browser-dependent, but provides interactions such as buttons and rollover image swapping. For form handling, pages that change content based on interactions, or even more advanced interactions, tools such as PHP, active server pages (ASP), and structured query language (SQL) are required. Some web pages are even programmed to allow the user to drag and drop content. Drag and drop may also be used as a navigation method for the website. In this case, the user may need to drag the image on the page to move the focus to a different area. There are software applications for building web pages, such as Adobe Dreamweaver and CoffeeCup.
