css extension. Dreamweaver notes that the file cannot be found and asks if you want to proceed. Click OK, and, when you create your first style, Dreamweaver also creates the CSS file with the requested filename. The final option on the Attach External Style Sheet dialog box, the Media list, is discussed in the next section. Choosingamediatype One of the most important facets of the Cascading Style Sheet specification is the ability to style a page for a specific media type. A media type is a means of communication, such as computer screen, printer, or TTY device. The W3C identifies eight different media types: aural, braille, handheld, print, projection, screen, TTY, and TV. If no media type is declared, the style sheet is applied to all devices that render the page. If one is declared, a media attribute is added to the code, like this (addition bolded for emphasis): type=???text/css??? media=???screen??? /> The bulk of today??™s designers do not apply a media type at all. However, an increasing number have started to create different style sheets: one to be viewed on the computer screen and another to be printed. Dreamweaver makes this easy by including a media list on the Attach External Style Sheet dialog box.
