      CSS樣式

      CSS的全稱是Cascading Style Sheet,中文譯作層疊樣式表。在設計制作網頁時,要考慮的最核心的兩個問題是“網頁內容是什么”和“如何表現這些內容”,可概括為“內容”和“表現”這兩個方面。過去由于CSS技術的應用還不成熟,人們更多地關注HTML,想盡辦法使用HTML同時承擔“內容”和“表現”兩方面的任務。而現在,CSS的應用已經相當完善和成熟,使用它可以制作出符合Web標準的網頁。Web標準的核心原則是“內容”和“表現”分離,HTML和CSS各司其職,即HTML用來決定網頁的結構和內容,CSS用來設定網頁的表現樣式。

      一、         CSS樣式的優點

      1.可以以前所未有的能力控制頁面布局

      HTML的控制能力很有限。我們不可能控制行間距或字間距,我們不能在屏幕上精確定位圖像的位置等。有了CSS之后,可以使用CSS樣式表減少表格標簽及其他加大HTML體積的代碼,從而減少文件尺寸。

      2.可以制作體積更小

      樣式表的主旨就是將格式和結構分離。對于樣式表,我可以將站點上所有的網頁都指向單一的一個CSS文件,我只要修改CSS文件中的某一行,那么整個站點都會隨之發生變動。
      CSS樣式表只是簡單的文本,就像HTML那樣。它不需要圖像,不需要執行程序,不需要插件,不需要流程,與HTML指令一樣快。

      3.可以將許多網頁同時更新

      沒有樣式表時,如果要更新整個站點中所有網頁文件文本的字體,必須一頁一頁地修改每個網頁文件。即便站點用數據庫提供服務,仍然需要更新所有的模板,而且更新每一模板,每一個實例的<FONT FACE>。
      有了CSS樣式,這一切變得再簡單不過了,只需要修改其中的CSS樣式表文件就可以達到修改整個網站頁面的效果。

      4.瀏覽器將成為更友好的界面

      不像其他的網絡技術,樣式表的代碼有很好的兼容性,也就是說,如果用戶丟失了某個插件時不會發生中斷,或者使用老版本的瀏覽器時代碼不會出現雜亂無章的情況。
      只要是可以識別CSS樣式表的瀏覽器就可以應用它,而隨著計算機軟、硬件的升級,絕大部分瀏覽者用的是較新版本的瀏覽器,它們能很好的支持CSS技術。
