這就是利用逗號 , 分開不同的標籤,也就是把每個選取項 (selector) 以逗號分開,如下例
1 2 3 4 5 6 7 8 9 10 11 | p, div, blockquote { color : white ; background-color : black ; } /* 《程式語言教學誌》的範例程式 檔名:demo07.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 */ |
此例中將 <p> 、 <div> 、 <blockquote> 三種 HTML 元素 (element) 都設定為黑底白字,我們以下面的 HTML 文件載入 demo07.css
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 = "demo07.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 > < div >There is no spoon.</ div > < div >I can only show you the door, you have to walk through it.</ div > < div >Choice. The problem is choice.</ div > < div >Then tomorrow we may all be dead, but how would that be different from any other day?</ div > < blockquote >I have dreamed a dream, but now that dream has gone from me.</ blockquote > < blockquote >Choice is an illusion, created between those with power, and those without.</ blockquote > < blockquote >Because I choose to.</ blockquote > < blockquote >Everything that has a beginning has an end.</ blockquote > </ body > </ html > <!-- 《程式語言教學誌》的範例程式 檔名:demo07.html 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 (broswer) 開啟如下

如果不用群組的寫法,就得逐一給每個標籤進行相同的樣式 (style) 定義,例如
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | p { color : white ; background-color : black ; } div { color : white ; background-color : black ; } blockquote { color : white ; background-color : black ; } /* 《程式語言教學誌》的範例程式 檔名:demo08.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 demo08.css
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 = "demo08.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 > < div >There is no spoon.</ div > < div >I can only show you the door, you have to walk through it.</ div > < div >Choice. The problem is choice.</ div > < div >Then tomorrow we may all be dead, but how would that be different from any other day?</ div > < blockquote >I have dreamed a dream, but now that dream has gone from me.</ blockquote > < blockquote >Choice is an illusion, created between those with power, and those without.</ blockquote > < blockquote >Because I choose to.</ blockquote > < blockquote >Everything that has a beginning has an end.</ blockquote > </ body > </ html > <!-- 《程式語言教學誌》的範例程式 檔名:demo08.html 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 --> |
