css中一个div可以同时设置左浮动和相对定位?
<ul>
                <li><a class="current_nav" href="#">网站首页</a>
                 <ul>
                     <span class="arrow"></span>
                     <li class="twomenu"><a href="#">域名查询</a></li>
                     <li class="twomenu"><a href="#">管理域名记录</a>
                         <ul>
                             <span class="arrow"></span>
                             <li><a href="#">域名查询</a></li>
                                <li><a href="#">管理域名记录</a></li>
                                <li><a href="#">域名查询</a></li>
                                <li><a href="#">管理域名记录</a></li>
                                <li><a href="#">域名查询</a></li>
                            </ul>
                        </li>
                        <li class="twomenu"><a href="#">域名查询</a></li>
                     <li class="twomenu"><a href="#">管理域名记录</a></li>
