类似网易发邮件的提示框的排版

css:

    .PopUpModel{ width:300px; background-color:#FFFFFF; border: 1px solid BLACK;  height:auto; text-align:center;}    .ctrl_title{ background-color:#f1f1f1; color:#000000; margin:0px; padding:7px 7px;text-align:left;width:300px; font-size:15px; FONT-WEIGHT: bold;} .ctrl_title img {float:right;}

<div id="alertdialog" class="PopUpModel" style="position: absolute; z-index: 101; left: 40%; top: 40%; display: none;">            <div class="ctrl_title">                <a onclick="closealert();" href="javascript:void(0);"><img border="0" src="../images/close.gif" /></a>警告            </div>            <div id="searchresult">                <table cellpadding="4" cellspacing="4">                    <tr>                        <td>                            <span id="alerterrorinfo"></span>                        </td>                    </tr>                </table>                <br />            </div>        </div>

红色为关键部分!
