问题描述
假设我有一个文档
<style type="text/css"> div { border:1px solid; padding:15px; } #i_am_relatively_positioned{ background-color:#fcc; margin:50px; padding:50px; position:relative; } #inner { background-color:#cfc; } #i_want_to_be_absolute_to_body{ background-color:#ccf; left:0; position:absolute; top:0; } </style> <body> <div id="i_am_relatively_positioned"> <div id="inner">inner</div> <div id="i_want_to_be_absolute_to_body">absolute to body</div> </div> </body>是否有办法使#i_want_to_be_absolute_to_body相对于body元素(而不是其直接相对容器)绝对定位?
Is there a way to make #i_want_to_be_absolute_to_body positioned absolute with respect to the body element, rather than its immediate relative container?
我知道我只能用一些负数上下，但这似乎很笨拙-这是我唯一的选择吗?
I know I can just use some negative top and left but that seems kludgey - is this my only option?
推荐答案您可以使用一些javascript来做到这一点(我假设您无法更改标记?).
You can use a bit of javascript to do this (I'm assuming you can't change the markup?).
document.body.appendChild(document.getElementById('i_want_to_be_absolute_to_body'));更多推荐
