这是我的例子：
线高不适用于流体div.我的代码目前基于行高,但框的大小会发生变化.那么如何才能在完全中间的链接(内容)？
我想确保这个DIV中的内容总是从顶部和侧面同样居中.垂直和水平居中.
<style type="text/css">
.Box{
width:468px; /* PHP changes this sometimes */
height:60px; /* PHP changes this sometimes */
background:#eee;
text-align:
center;
border:
1px solid rgb(177,172,171);
line-height: 61px;
}
</style>
<div style="" class="Box" id="">
<a style="color:#333;font-weight:bold" href="claimPrize();">Winner!</a>
</div>
解决方法
不久前进入类似的情况,做了一个搜索,发现了一篇关于css-tricks的绝对居中的文章,here是文章和随之而来的测试它的小提琴.
CSS
/* This parent can be any width and height */
.block {
text-align: center;
}
/* The ghost,nudged to maintain perfect centering */
.block:before {
content: '';
display: inline-block;
height: 100%;
vertical-align: middle;
margin-right: -0.25em; /* Adjusts for spacing */
}
/* The element to be centered,can
also be of any width and height */
.centered {
display: inline-block;
vertical-align: middle;
width: 300px;
}
HTML
<div class="block" style="height: 300px;">
<div class="centered">
<h1>Some text</h1>
<p>But he stole up to us again,and suddenly clapping his hand on my shoulder,said—"Did ye see anything looking like men going towards that ship a while ago?"</p>
</div>
</div>
<div class="block" style="height: 200px;">
