我是XHTML和CSS世界的新手。我把一個需要3列布局的頁面放在一起。該代碼在Internet Explorer,Firefox和Google Chrome中爲我帶來了期望的效果,但我不確定它是否是正確的代碼編寫方式。XHTML CSS 3列布局
我已經發布了它的代碼之前它的工作,並在應用必要的更改,使其工作。
問題
- 這是正確的方式來編碼呢?
- 這是編碼的最佳方式嗎?
- 我可以在代碼中遇到什麼問題?
之前,它的工作

哇這是一個非常寬泛的問題 – Kieran 2011-05-19 01:53:09
@Kieran - 它是如何廣泛?如果需要,我可以更新這個問題。 – PeanutsMonkey 2011-05-19 01:57:25
@基蘭 - 不是很廣泛 - 它只是評論一些代碼:) – easwee 2011-05-19 09:04:54
