我似乎无法理解什么是怎么回事：CSS - 垂直居中
我要垂直居中的iframe &另一个div这两个水平将坐在一起彼此。
我所做的是我已经将上述两个（iframe和div）放在另一个名为“iframe_r_container”的div内，并将其定位为绝对& display set as table。
HTML：
<body id="container">
<div id="menu_bars">
<div id="main_bar">
<ul>
<li class="maintabs"><a href="#">a</a></li><li class="maintabs"><a href="#">b</a></li><li class="maintabs"><a href="#">c</a>
</li><li class="maintabs"><a href="#">d</a></li>
</ul>
</div>
<div id="filemenu">
<ul>
<li class="filetabs"><a href="#">File</a></li><li class="filetabs"><a href="#">Edit</a></li><li class="filetabs"><a href="#">Settings</a></li>
</ul>
</div>
</div>
<div id="iframe_r_container">
<iframe id="iframing" src="mannequin.html" frameborder="0" ></iframe>
<div id="right_container">
<div id="user_credit">
<h1><a href="#">Username</a></h1><br />
has <span id="credits">000</span> credits.
</div>
<div> <button id="template_button"><img src="images/Coutallure-WebApp/template_button.png" /><span>Templates</span></button> </div>
<!-- contains the jquery widget for displaying the features, i.e. buttons, zips etc -->
<div id="features_container">
</div>
</div>
</div> </body></html>
这里是CSS：
/* RESETS */

..........它的推移和及以下问题区域，我认为
/* START OF IFRAME_R_CONTAINER */

}

/* END OF IFRAME */

你能给出它的样子的截图吗？ – corroded 2011-02-04 06:47:28
