| Cascading Style Sheet. Style sheets contain style definitions that allow a user to control how various web page elements (margins, font size & colour, cell background etc.) are to be displayed. Styles can be applied to HTML tags, or freely defined as classes. A entire website can be formatted simply by linking each page to a single external stylesheet, making stylesheets very practical. Additionally, styles can be embedded directly into the HTML code ("inline") to change the appearance of that particular web page. |
