Support for Cascading Style Sheets

XHTML and Cascading Style Sheets (CSS) are designed to separate content from its

presentation. XHTML and WML tags were originally designed to define the content of a

document. In this way, the same content can be rendered on diverse devices. Most XHTML

elements are semantic elements, that is, they convey meaning about their content rather than

information on how to display it. For example, the <em> element contains content that should

be emphasized. It is up to the browser to figure out how to render the emphasis, with a different

typeface, a louder voice, or in another way. Style sheets are a way to manage a Web page’s

overall look such as the page background, background color or font color.

A style is a rule that tells the browser how to render a particular tag’s contents. Each tag has a

number of style properties associated with it, whose values define how that tag is rendered by

the browser. A rule defines a specific value for one or more tag properties. Style Sheets allow

style information to be specified in many ways. The Web browser supports the inline style

where a style attribute and tag along with a list of properties and their values are specified. The

browser uses those style properties and values to render the tag’s contents.

The browser supports CSS2. CSS2 is compatible with both WML and XHTML and can be

re-used if the browser evolves to XHTML. See http://www.w3.org/TR/CSS21/cascade.html

for

further details about CSS2.
