那時、天下人的口音言語、都是一樣。他們往東邊遷移的時候、在示拿地遇見一片平原、就住在那裏。他們彼此商量說、來吧、我們要作磚、把磚燒透了。他們就拿磚當石頭、又拿石漆當灰泥。他們說、來吧、我們要建造一座城、和一座塔、塔頂通天、為要傳揚我們的名、免得我們分散在全地上。耶和華降臨要看看世人所建造的城和塔。耶和華說、看哪、他們成為一樣的人民、都是一樣的言語、如今既作起這事來、以後他們所要作的事、就沒有不成就的了。我們下去、在那裏變亂他們的口音、使他們的言語、彼此不通。於是耶和華使他們從那裏分散在全地上。他們就停工、不造那城了。因為耶和華在那裏變亂天下人的言語、使眾人分散在全地上、所以那城名叫巴別。

表格排版
為什麼要用CSS表格排版有什麼問題？
表格 ̶ 排版根本無關
<table>有規則的資料
沒有選擇table, table, or me?
<table cellpadding="0" cellspacing="0" border="0">
Grids
缺點•冗長的HTML語法 = size++
•不必要的定位用圖片 = request++•語法沒有結構性 = extend--•更新維護不易 = cost++
