早上找了一篇《div里面css控制图片垂直居中的解决办法》文章,下午又找到一篇更全更好的。贴上来给大家:
当writing-mode为tb-rl 时,文档流是从上到下,从右到左书写。然后设置text-align: center就可以实现垂直方向上的居中。算是一个小技巧吧。
IE6下用writing-mode实现
未知高度替换元素垂直居中。

因为Opera,FF3,IE8均支持display:talbe;这些特性了,因此改进的办法是:

- <body>
- <h1>固定高宽的容器中,图片垂直局中。</h1>
- <p>绿色容器是span,目的是使自己的左上角与容器中心点对齐。红色是具体图片,再次设置负值使自己的中心点和父容器的中心点重合,最终达到垂直局中的目的。</p>
- <div class="miao">
- <span><img src="http://bbs.blueidea.com/images/default/logo.gif" alt="Logo" /></span>

如果不喜欢条件注释,可自行将代码以css hack的方式拼凑起来。
