      自定義類別(相關css教程
        今天講的有一個新知識“類別”。其實,這知識并不陌生!回想一下,在 HTML 標簽中,有個屬性叫 class,當時沒有解釋這個屬性是干什么用的。其實,不是不解釋,而是解釋了也不會用,所以就暫時沒有說,等到了今天。這個 class 屬性,所以將之解釋為“類別”屬性,它有什么作用呢?它能夠讓我們在不同的標簽中使用相同的 CSS 設定,舉個例子如下: 我們在讀書的時候,常常看到課本上有重點的地方,用紅色或其它顏色標明。如果,今天我們的網頁上,也想將一些比較重要的地方用“紅色、粗體字”來顯示,你會怎么做呢?:
      原始代碼 “<font color="Red"><b>網頁陶吧</b></font>”
      顯示結果 網頁陶吧
