What is CSS (Cascading Style Sheets)?
Cascading Style Sheets, style
sheets when attached to documents describe how the
document is displayed or printed, e.g. a CSS sheet
is attached to a HTML (Hyper Text Markup Language)
document, to influence its layout when it is accessed
via a computer Internet browser such as Internet Explorer
or Netscape.
Cascading Style Sheets are used by both
web site authors and readers of web pages to define
colors, fonts, layout, and other aspects of web site
document presentation.
