我有CSS一個div因爲這如何設置此高度自動div？
#middle2 {
background: none repeat scroll 0 0 #ffffff;
border: 1px solid #e5e5e5;
border-radius: 15px;
height: 480px;
margin-left: 230px;
margin-top: 20px;
position: absolute;
width: 500px;
}
的HTML是這個
<div id="middle2" style="height: auto; overflow: hidden;">
<div id="envelop"></div>
<div id="envelop_title">Create your Account</div>

但問題是我收到的股利以這種方式？
我怎樣才能解決這個問題。我想div應該有自動高度，它會自動伸展
Post full CSS +嘗試在div上使用'relative'定位和'z-index：100;'。 – 2015-02-08 17:42:23
首先，將單獨的CSS文件中的樣式與內聯樣式混合並不是一個好主意。你已經聲明瞭固定的'height：height：480px';在'＃middle2'樣式中，然後用inline'style =「height：auto; ...'覆蓋它;如果可以的話，避免這種情況 - 只能在單獨的CSS文件中定義樣式，如果希望它自動伸展，所有高度樣式（'height：auto;'默認使用）;其次，你指定了'position：absolute;'這意味着你已經打破了DOM組件的流動，這就是爲什麼footer沒有被壓下的原因。相對;'@ThePragmatick說 – Fallup 2015-02-08 17:48:32
