我有一個網站，我正在努力完善佈局。但是我現在面臨的問題是專欄不會一路走到最後。我已閱讀關於如何從另一個人獲得CSS列3佈局的教程http://www.ejeliot.com/blog/61幫助在CSS網站上創建高度相等的列
問題是我仍然迷路。任何人都可以看看這個簡單的模板（www.centuryautosd.com/help.asp）並製作CSS，這樣無論頁面有多高，列都會一路向下。數據是動態生成的，因此高度要求會隨着每個查看頁面的變化而不斷變化。 以下是真實網頁的鏈接：www.centuryautosd.com/help.asp
謝謝！

它使用在你的鏈接頁面，其中有用於每個列的負面底部邊緣，然後用溢出的容器藏，以中http://www.ejeliot.com/samples/equal-height-columns/example-4.html描述的技術隱藏粗糙的邊緣。我沒有將這項技術應用到中間欄，因爲它顯示欄總是最長的，但如果最終出現在中間欄不是最長的情況並導致佈局問題的情況下，您可以應用相同的技術，方法是將
margin-bottom: -2000px;
padding-bottom: 2000px;
在它的風格。
總而言之，我所做的是添加一個容器div，它包含佈局中的三列。然後，我爲容器添加了一個隱藏的溢出，並將上面顯示的邊距&填充到列中。
這工作！非常感謝。對於某些頁面而言，這還不夠長，但是我將記錄集顯示器一次只顯示10輛汽車並解決了這個問題。 謝謝 如此多！ – Drea 2009-12-17 19:42:26
要延長它，只需將-2000像素和2000像素的邊距和填充設置更改爲3000或4000或任何需要的設置即可。 – 2009-12-17 19:54:14
好的，謝謝布賴恩 – Drea 2009-12-17 20:06:49
