我不能將頂部邊距加到使用明確的底部:二者。 使用填充似乎可以解決問題。但是它毀掉了頁腳的最高固定邊界。不能將頂部邊距加到使用明確的底部:均爲

我不確定你是什麼意思與清除浮游物。如果我將清除添加到左列和右列,則內容被毀壞。如果我刪除了浮動內容也被破壞了。 – alexchenco 2009-06-28 21:06:22
浮動物沒有高度,所以您的#container div不會伸展到底部。請參閱此頁http://www.quirksmode.org/css/clearing.html以獲得一個很好的解釋。使用#container {width:800px; margin:0px auto; overflow:hidden;}使容器div「清除」浮動。 – Emily 2009-06-28 21:18:45
