我一直想用CSS定位替換我的網站中的表格，並一直試圖通過教程等自學。我已經有一些早期的成功，但它都崩潰了我試圖創建一個側邊欄。我希望問題有一些簡單的解決方案。元素的相對/絕對定位不會接近我想要做的。我的目標是創建一個帶有從上到下堆疊（浮動？）圖像的側欄，中間元素是無序列表的一部分。我有一次工作，但現在堆疊在一起。它必須是我設置浮動和絕對/相對定位的方式。在閱讀了一些文章之後，我嘗試添加一個div封裝器，將它們放在裏面，但我覺得自己變得更加困惑。是否有人可以推動我朝着正確的方向發展？下面是代碼：簡單的css定位（我認爲）

難道你把你的代碼上[的jsfiddle（http://jsfiddle.net/）？ – Wex
這看起來很酷！我會盡力解決這個問題。謝謝 – Dana
