问题描述
我有很奇怪的问题,在大多数浏览器(即ff,chrome,safari)。
以下是示例代码:
<!DOCTYPE html PUBLIC - // W3C // DTD XHTML 1.0 Transitional // ENhttp://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">
< html xmlns =http://www.w3.org/1999/xhtml>
< head>
< meta http-equiv =Content-Typecontent =text / html; charset = utf-8/>
< style type =text / css>
html {
outline:1px#0ff solid;
background:rgba(0,255,255,0.1);
}
body {
margin:0;
padding:0;
outline:1px#00f solid;
background:rgba(0,0,255,0.1);
}
#aDiv {
width:300px;
outline:1px#f00 solid;
background:rgba(255,0,0,0.2);
}
#bDiv {
margin-top:100%;
outline:1px#0f0 solid;
background:rgba(0,255,0,0.1);
}
< / style>
< / head>
< body>
< div id =aDiv>
< div id =bDiv>
content
< / div>
< / div>
< / body>
< / html>
当您更改#aDiv宽度时,#bDiv margin-top会以相同的值更改。
我不知道怎么可能,那个高度到宽度。
最好的问候;)

p>解决方案
很无用,对不对?您是否考虑过使用 position:absolute
和 bottom:0
?他们可能更多的是你要找的。 p>
I have very strange "issue", on most browsers (ie, ff, chrome, safari).Here is example code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style type="text/css">
html{
outline: 1px #0ff solid;
background: rgba(0,255,255,0.1);
}
body{
margin: 0;
padding: 0;
outline: 1px #00f solid;
background: rgba(0,0,255,0.1);
}
#aDiv{
width: 300px;
outline: 1px #f00 solid;
background: rgba(255,0,0,0.2);
}
#bDiv{
margin-top: 100%;
outline: 1px #0f0 solid;
background: rgba(0,255,0,0.1);
}
</style>
</head>
<body>
<div id="aDiv">
<div id="bDiv">
content
</div>
</div>
</body>
</html>
When You change #aDiv width, then #bDiv margin-top will change with same value.I dont know how it is possible, that height goes to width. Anyway maybe one of You could explain me whats going on?
Best regards ;)

解决方案
This is actually according to the spec
Pretty useless, right? Have you considered using position: absolute
and bottom: 0
? They might be more of what you're looking for.
