how to remove white border around the div
提问by newday
I am trying to develop a web site from scratch. Here is the code
我正在尝试从头开始开发一个网站。这是代码
<html>
<head>
</head>
<body >
<div id="top" style="height:200px;background-color:green">
</div>
<div id="middle" style="height:800px;background-color:white">
</div>
<div id="footer" style="height:200px;background-color:green">
</div>
</body>
</html>
Problem is that there is a white space around above div tags. I can remove white space using margin: -10px;property. But I don't like to handle it that way. Is there way to handle this in decent way in css?
问题是 div 标签上方有一个空白区域。我可以使用margin: -10px;属性删除空格。但我不喜欢那样处理。有没有办法在 css 中以体面的方式处理这个问题？

Set the margin for the body to 0;
将正文的边距设置为 0；
<body style = "margin:0">
