空div(样式:高度)将不会显示 [英] Empty div (with style: height) will not display
问题描述
令人难以置信的简单的HTML片段-但未显示我的期望。
Incredibly simple piece of HTML - but not displaying how I would expect.
我正在尝试创建一个空div,该空白div在页面顶部显示为空白,其 style = height:400px;
I'm trying to create an empty div that displays as whitespace on the top of the page, with style="height: 400px;"
即使我指定了高度,我的空div也不会显示。我在这里想念什么?
Even though I have specified a height, my empty div will not display. What am I missing here?
更新:我的主要问题是:即使设置了高度,为什么不显示空div?或者,显示空div所需的基本样式
规则是什么?
UPDATE: my main question is: Why does an empty div not display even if it has a height set? Or, what are the basic style
rules needed to display an empty div?
完整代码:
<html>
<head><title>Site Name</title>
</head>
<body>
<div style="height:400px; width:100%; margin:0; padding:0; position:absolute;"></div>
<div style="width: 50%; margin: auto;">
<img src="logo.gif"></div>
<div style="width: 50%; margin: auto;"></div>
</body>
</html>
推荐答案
如果只想添加空格,请尝试以下
If you just want to add white space try this
<div style="height:400px; width:100%; clear:both;"></div>
或者您可以像 body {padding-top:400px; }
