IntroDuction to Css

 

Why use CSS?

• Easy to maintain - The power of CSS is that a single CSS file can be used on a multiple number of HTML documents at the same time. This allows for the ability to make a site wide design change by only changing one CSS file rather than going into multiple HTML documents.

• Smaller file sizes - CSS allows authors to remove all presentation from HTML documents, including layout tables, spacer images, decorative images, text presentation and a lot more. This dramatically decreases the file size of HTML documents.

• Increased Accessibility - CSS when combined with well structured HTML documents can aid in allowing devices such as screen readers to provide a more accessible page. When all presentational markup is removed, the only thing a screen reader encounters is structural content. CSS can also be used to increase the clickable area of links as well as control line and text line widths for users with motor skill or cognitive difficulties.

• Different Media - CSS can be style specifically for different media, including browsers, printers, handheld devices, and projectors.

• More control over typography - CSS allows authors to control the presentation of content with properties such as capitalize, uppercase, lowercase, text-decoration, text-indent etc. CSS can also be used to add margins, borders, padding, background color, and background images to any HTML element.

 

World Wide Web Consortium (W3C)

CSS is a recommendation of the World Wide Web Consortium (W3C). The W3C is an industry consortium of web stakeholders including universities; companies such as Microsoft, Netscape, and Macromedia; and experts in web related fields.

One of the W3C's roles is to produce recommendations for a range of aspects of the Web. CSS1 became a recomendation in late 1996, CSS2 became a recommendation in May 1998, and CSS2.1 became a recommendation in January 2003.
