      • css教程之樣式表極大地提高了工作效率

      • 2015-01-19 14:19 來源:未知
      樣式表極大地提高了工作效率(相關css教程
      樣式表定義如何顯示 HTML 元素,就像 HTML 3.2 的字體標簽和顏色屬性所起的作用那樣。樣式通常保存在外部的 .css 文件中。通過僅僅編輯一個簡單的 CSS 文檔,外部樣式表使你有能力同時改變站點中所有頁面的布局和外觀。
      由于允許同時控制多重頁面的樣式和布局,CSS 可以稱得上 WEB 設計領域的一個突破。作為網站開發者,你能夠為每個 HTML 元素定義樣式,并將之應用于你希望的任意多的頁面中。如需進行全局的更新,只需簡單地改變樣式,然后網站中的所有元素均會自動地更新。
      多重樣式將層疊為一個
      樣式表允許以多種方式規定樣式信息。樣式可以規定在單個的 HTML 元素中,在 HTML 頁的頭元素中,或在一個外部的 CSS 文件中。甚至可以在同一個 HTML 文檔內部引用多個外部樣式表。
      層疊次序
      當同一個 HTML 元素被不止一個樣式定義時,會使用哪個樣式呢?
      一般而言,所有的樣式會根據下面的規則層疊于一個新的虛擬樣式表中,其中數字 4 擁有最高的優先權。
      1. 瀏覽器缺省設置
      2. 外部樣式表
      3. 內部樣式表(位于 <head> 標簽內部)
      4. 內聯樣式(在 HTML 元素內部)
      因此,內聯樣式(在 HTML 元素內部)擁有最高的優先權,這意味著它將優先于以下的樣式聲明:<head> 標簽中的樣式聲明,外部樣式表中的樣式聲明,或者瀏覽器中的樣式聲明(缺省值)。
