舉例如下
1 2 3 4 5 6 7 8 9 10 11 | body { color : white ; background-color : navy ; } /* 《程式語言教學誌》的範例程式 檔名:background01.css 功能:示範 CSS 2.1 樣式表的使用 作者:張凱慶 時間:西元 2011 年 7 月 */ |
我們以下面的 HTML 文件載入
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | < html > < head > < title >網頁標題</ title > < link rel = "stylesheet" type = "text/css" href = "background01.css" > </ head > < body > < p >You ever have that feeling where you're not sure if you're awake or still dreaming?</ p > < p >A prison for your mind.</ p > < p >Free your mind.</ p > < p >Believe the unbelievable.</ p > < p >There is no spoon.</ p > < p >I can only show you the door, you have to walk through it.</ p > < p >Choice.

瀏覽器 (broswer) 開啟如下

此例中將 <body> 設定的深藍底白字,所以 <body> 的所有子代 (child) 元素 (element) 都繼承 (inherit) 深藍底白字的樣式 (style) 。
另舉一例如下
1 2 3 4 5 6 7 8 9 10 11 | .example { color : white ; background-color : navy ; } /* 《程式語言教學誌》的範例程式 檔名:background02.css 功能:示範 CSS 2.1 樣式表的使用 作者:張凱慶 時間:西元 2011 年 7 月 */ |

瀏覽器開啟如下

此利用類別選取器 (class selector) example ,所以只有設定成 example 類別 (class) 的 <p> 才是深藍底白字。
