      • css教程之樣式解決了一個普遍的問題

      樣式解決了一個普遍的問題(相關css教程
      HTML 標簽原本被設計為用于定義文檔內容。通過使用 <h1>、<p>、<table> 這樣的標簽,HTML 的初衷是表達“這是標題”、“這是段落”、“這是表格”之類的信息。同時文檔布局由瀏覽器來完成,而不使用任何的格式化標簽。
      由于兩種主要的瀏覽器(Netscape 和 Internet Explorer)不斷地將新的 HTML 標簽和屬性(比如字體標簽和顏色屬性)添加到 HTML 規范中,創建文檔內容清晰地獨立于文檔表現層的站點變得越來越困難。
      為了解決這個問題,萬維網聯盟(W3C),這個非營利的標準化聯盟,肩負起了 HTML 標準化的使命,并在 HTML 4.0 之外創造出樣式(Style)。
      所有的主流瀏覽器均支持層疊樣式表。
