Introduction to Style Sheets
A style sheet is a simple mechanism for adding style (for example fonts, colors, spacing) to Web
documents.
The World Wide Web Consortium (W3C) has actively promoted the use of style sheets on the
Web since the Consortium was founded in 1994. The W3C has made several recommendations
including CSS1, CSS2, XPath, XSLT and XSL. CSS (Cascading Style Sheets) especially are
widely implemented in browsers.
By attaching style sheets to structured documents on the Web (for example HTML), content
authors and web developers can influence the presentation of documents without sacrificing
device-independence or adding new HTML tags.
Style sheets can be used to define the appearance of an entire site in a consistent way. With the
introduction of CSS, it is now recommended that layout-specific features in HTML be phased out
and replaced by style sheets.
Understand Cascading Style Sheets
Cascading Style Sheets (CSS) provide a means for web authors to separate the appearance of web
pages from the content of web pages. This means that the content of the web site should go into
your HTML files (or XHTML files or JSP pages), but these files should not describe how that
information is displayed. Information about how the pages should appear goes into CSS files. The
styles from this file that is given a .css extension are then applied server-side.
