What will be an ideal response?
To add presentation information to web pages, web designers use a style language called Cascading Style Sheets (CSS). With CSS you can display information for different devices, lay out page designs, and control typography, color, and many other presentation characteristics.?CSS lets you control the presentation characteristics of an entire web site with a single style sheet document. For example, assume you want all of your
headings to appear green and centered everywhere on your web site. Prior to CSS you might have included the following code for every instance of an element:?Some Heading Text
?Using a CSS rule, you can express the same style as follows:?h1 {color: green; text-align: center;}?You can place this rule in an external style sheet and then link every page on your site to that style sheet; the single rule controls every element in your web site. Later, if you want to change the color to red, you simply revise the style sheet rule to change every page on your site.
