      • css教程之偽類——動態鏈接

      • 2015-01-22 12:55 來源:未知
      :偽類——動態鏈接(相關css教程
      偽類可以看做是一種特殊的類選擇符,是能被支持CSS的瀏覽器自動所識別的特殊選擇符。它的最大的用處就是可以對鏈接在不同狀態下定義不同的樣式效果。
       1.  語法
           偽類的語法是在原有的語法里加上一個偽類(pseudo-class):
       selector:pseudo-class {property: value}(選擇符:偽類 {屬性: 值})
         偽類和類不同,是CSS已經定義好的,不能象類選擇符一樣隨意用別的名字,根據上面的語法可以解釋為對象(選擇符)在某個特殊狀態下(偽類)的樣式。類選擇符及其他選擇符也同樣可以和偽類混用:
            selector.class:pseudo-class {property: value}
            (選擇符.類:偽類 {屬性: 值})
      2.  錨的偽類
      我們最常用的是4種a(錨)元素的偽類,它表示動態鏈接在4種不同的狀態:link、visited、active、hover(未訪問的鏈接、已訪問的鏈接、激活鏈接和鼠標停留在鏈接上)。我們把它們分別定義不同的效果:
       a:link {color: #FF0000; text-decoration: none} /* 未訪問的鏈接 */
       a:visited {color: #00FF00; text-decoration: none} /* 已訪問的鏈接 */
       a:hover {color: #FF00FF; text-decoration: underline} /* 鼠標在鏈接上 */
       a:active {color: #0000FF; text-decoration: underline} /* 激活鏈接 */
      (上面這個例子中,這個鏈接未訪問時的顏色是紅色并無下劃線,訪問后是綠色并無下劃線,激活鏈接時為藍色并有下劃線,鼠標在鏈接上時為紫色并有下劃線) 注意:有時這個鏈接訪問前鼠標指向鏈接時有效果,而鏈接訪問后鼠標再次指向鏈接時卻無效果了。這是因為你把a:hover放在了a:visited的前面,這樣的話由于后面的優先級高,當訪問鏈接后就忽略了a:hover的效果。所以根據疊層順序,我們在定義這些鏈接樣式時,一定要按照a:link, a:visited, a:hover, a:actived的順序書寫。
          3.  偽類和類選擇符
          將偽類和類組合起來用,就可以在同一個頁面中做幾組不同的鏈接效果了,例如,我們定義一組鏈接為紅色,訪問后為藍色;另一組為綠色,訪問后為黃色:
       a.red:link {color: #FF0000}
       a.red:visited {color: #0000FF}
       a.blue:link {color: #00FF00}
       a.blue:visited {color: #FF00FF}
       現在應用在不同的鏈接上:
       <a class="red" href="...">這是第一組鏈接</a>
       <a class="blue" href="...">這是第二組鏈接</a>
         4.  其他偽類
          此外CSS2還定義了首字和首行(first-letter和first-line)的偽類,可以對元素的首字或首行設定不同的樣式。下面看這個例子,我們在段落標記里定義文本首字尺寸為默認大小的3倍:
       <style type=”text/css”>
       p:first-letter {font-size: 300%}
       </style>
       ……
       <p>
       這是一個段落,這個段落的首字被放大了。
       </p>
       我們再定義一個首行樣式的例子:
       <style type=”text/css”>
       div:first-line {color: red}
       </style>
       ……
       <div>
       <p>
       這是段落的第一行
       這是段落的第二行
       這是段落的第三行
        </p>
        </div>
        (上例中段落的第一行為紅色,第二、三行為默認顏色)
        注意:首字和首行的偽類需要IE5.5以上的版本支持。
