Cascading Style Sheets


Cascading Style Sheets (CSS) are a component of Dynamic HTM or DHTML. CSS allows you to have dynamic control over all the design elements of your web site. All the design properties for your website are stored within a separate file. All your web pages link to this file to get their design information. You only need to edit one file to change the design elements on your entire website.

CSS allows you to separate the design of your web pages from the page's content. They can make a site more accessible creating a very flexible site that is not limited to only working in typical browsers. CSS allows users with special needs to replace your style sheet with their own style sheet.

They make your web site much easier to maintain and more accessible for your users.

Requirement:

When Cascading Style sheets are used, the web pages must make sense when the style sheet is turned off.
