Cascading Style Sheets

Cascading Style Sheets (CSS)

What is CSS?

                      CSS (cascading stylesheets) is a simple mechanism for
                      controlling the style of a Web document without compromising
                      its structure. By separating visual design elements (fonts,
                      colors, margins, and so on) from the structural logic of a Web
                      page, CSS give Web designers the control they crave without
                      sacrificing the integrity of the data - thus maintaining its
                      usability in multiple environments. In addition, defining
                      typographic design and page layout from within a single,
                      distinct block of code - without having to resort to image
                      maps,   tags, tables, and spacer GIFs - allows for faster
                      downloads, streamlined site maintenance, and instantaneous
                      global control of design attributes across multiple pages.

How CSS Works

                      CSS overrides the browser's default settings for interpreting
                      how tags should be displayed, letting you use any HTML
                      element indicated by an opening and closing tag (including the
                      tag) to apply style attributes defined either locally or in a
                      stylesheet.

                      Stylesheets contain rules, composed of selectors and
                      declarations that define how styles will be applied. The selector
                      (a redefined HTML element, class name, or ID name) is the link
                      between the HTML document and the style. There are two
                      different kinds of selectors: types (HTML element tags) and
                      attributes (such as class and ID...
