我希望能够将包含元数据(例如标题和作者)的 div 垂直居中在具有流体宽度的容器中。在下面的示例中,我希望 .meta div 在文章中垂直居中,这是流体宽度。
我尝试关注这篇文章(http://css-tricks.com/centering-in-the-unknown/),但它不起作用。
HTML
<div class="container">
<h3>Test</h3>
<article>
<div class="meta">
<div class="title"></div>
<div class="author"></div>
<img src="" />
</div>
</article>
</div>
CSS(使用 LESS)
