Using HTML In MS Office

HTML (Hypertext Markup Language) is the fundamental language behind all Web activity. It defines a set of operators, called tags that control how information is displayed in a browser, and how the browser is to react to certain events. There is (at least in theory) only one correct way to display each tag: An <H1> heading in one browser should look the same as an <H1> heading in all browsers.

HTML is the basic (some would say "old") technology that drives the Web: Any browser will support early versions of HTML, and most HTML pages based on the classic (read: "old") tags will display perfectly well in any browser. But like so many other components of the Web, HTML has evolved on Web time, mutating so quickly that it's difficult to keep track of the various standards from day to day.

Office applications take advantage of many advanced HTML features, including those that go way beyond the traditional HTML tags. The following features in particular are likely to cause some document formatting to display incorrectly when viewed in particular browsers:

• Extensible Markup Language (XML) incorporates tags that go beyond the capability of standard HTML to describe and present data. It takes HTML further by introducing the concept of a style sheet. Style sheets add a new dimension to HTML. They allow an individual user to specify how the browser should interpret a tag. If your machine has a style sheet that declares all <H1> headers appear in blue, then they'll always appear in blue—on your machine. -Most advanced Office features rely on XML to help them sur­vive the round trip between the application that created them and the browser.

• Cascading style sheets (CSS) make style sheets more flexible by allowing inheritance (simi­lar to Word's "Based On" styles), and automatically generated text and graphics. They extend basic HTML with style properties that define fonts, colors, margins, and other formatting properties. If you view a Web page that contains a CSS in a browser that can't interpret it, the browser displays the page using its default fonts and layout prop­erties.

• Dynamic HTML (DHTML) allows a Web page designer to add effects to text and images, such as hiding or displaying a block of text when the user clicks it.
