\[code\]<style type="text/css">.square { width:251px; height:207px; border: 1px solid #d6d6d6; -webkit-box-shadow: 1px 1px 3px rgba(0,0,0,.1); -moz-box-shadow: 1px 1px 3px rgba(0,0,0,.1); box-shadow: 1px 1px 3px rgba(0,0,0,.1); margin: 10px; overflow: hidden; position: relative; background-color:#fff; /*display: inline-block;*/ float: left; cursor: pointer; text-align: left;}.square img { display: block; margin: 0px; padding: 9px; width:234px !important; height:190px !important; position:absolute;}.square .caption { width:214px; height:170px; background:#000; color:#fff; padding:10px; position:absolute; left:9px; top:9px; /*display:none;*/ filter:alpha(opacity=80); -moz-opacity:0.8; -khtml-opacity: 0.8; opacity: 0.8;}.square .text{ border:1px dotted #d6d6d6; margin: 10px; padding: 5px; vertical-align: center; max-height: 100px; overflow: auto;}.square .until { font-size: 12px; font-style: italic; position: absolute; right: 10px; bottom: 5px;}</style><div class="square"> <a href="http://stackoverflow.com/" > <img width="234" height="190" src="http://stackoverflow.com/questions/14034769/files/2011/12/17.jpg" alt="17" title="17"/> </a> <a href="http://stackoverflow.com/" rel="bookmark"> <div class="caption"> <h2>Half A Beatle</h2> <div class="text">lol</div> <div class="until">Until: 01 01 2012</div> </div> </a></div>\[/code\]

So is it possible to center div in current situation?
