Explain what CSS3 is and how it is used. Include in your answer an explanation of the two ways in which webpages can be designed.
What will be an ideal response?
CSS3 is the new standard for website presentation. Webpages can be designed in two ways. First, a webpage can contain layout and content information combined in a single HTML file. This option is not recommended because it is difficult to update and maintain such a webpage on larger sites. Second, a webpage can separate content from the layout in two separate files. The content information is coded in the HTML file, but the HTML file does not contain information about how that information is displayed. The appearance, or layout, is stored in a separate file called a CSS file.?A CSS file is a simple text file containing style rules that control the appearance of a webpage. Using CSS styles, you can control font size, font color, background, and many other attributes of a webpage, thus reducing a page's file size. In a large website that does not use CSS styles, making a formatting revision such as changing the font is very time consuming because each page must be changed individually to use the new font. By using CSS, you can change the font in one line of a CSS file and automatically update the font throughout the entire site.
