In the previous example, serif is the last font in the list. If the user doesn't have courier or times , the browser will use the generic font instead. You can also use a percentage, which is relative to the parent element's font size. You can also use one of the values shown in Table B.12. The W3C recommendation that browser programs use a scaling factor of 50 percent is only a recommendation.
Vendors are free to use any scaling factor that they want.
Thus, the values in Table B.12 are only guidelines. You can change the style of the font by using the font-style property. Table B.13 describes the possible values. You use the font-variant property to display text in small caps. Setting this property to normal causes the browser to display the text normally.
