Question

我正在尝试使用CSS创建浮动菜单。当我向下滚过标题图像时，我希望div保持在顶部。我尝试使用“position：fixed”但是留下了一个空白。反正将菜单包装div从相对转换为固定吗？ enter image description here

CSS

/*** Header ***/
#header         { width: 100%; background-color: #000; z-index: 2000; height: 50px; margin: 0 0; border-top: 1px solid #464646; border-bottom: 1px solid #464646; position: fixed}
#topheader      {height: 110px; background: #333; width:970px; margin: 0 auto; position: relative;}
#topheadleft    {float: left; width: 50%; font-family: font1; font-size: 46px; margin-top: 15px; }
#topheadright   {float: left; width: 50%}
.callus { color: #fff; font-size: 20px; font-family: font4; text-shadow: 2px 2px #000}
.hardwork  {color: #fff; font-family: font3; font-size: 12px; text-transform:capitalize;  }
#topheadwrap { background: #333; padding: 0 0; margin: 0 auto;  }
.fixed { position:fixed; top:0; }

HTML

<div id="topheadwrap">
        <div id="topheader">
                <div id="topheadleft">
                        <span style="color:#FF4B45; text-shadow: 2px 2px #000;">East Coast</span><span style="color: #3A8CFF; text-shadow: 2px 2px #000;"> Martial Arts</span><br />
                        <div style="margin-top:-30px; clear: both"><span class="callus">Call Us Now: 845-440-7715</span></div>
                        <div style="margin-top:-35px; clear: both"><span class="hardwork">Hard work, dedication, challenging, authentic</span></div>
                </div>
            <div id="topheadright"></div>
        </div>
    </div>


     <div id="header">

        <div id='cssmenu'>
<ul>
   <li><a href='#'><span>Home</span></a></li>
   <li class='has-sub'><a href='?page_id=39#box3'><span>About Us</span></a>
      <ul>
         <li class='has-sub'><a href='#'><span>The School</span></a>
         </li>
         <li class='has-sub'><a href='http://www.eastcoastma.com/?page_id=158'><span>Instructors</span></a>
         </li>

      </ul>
   </li>
   <li><a href='?page_id=56'><span>Classes</span></a></li>
   <li><a href='?page_id=15'><span>Schedule</span></a></li>
   <li><a href='#'><span>News</span></a></li>
   <li><a href='?page_id=69'><span>Programs</span></a></li>
   <li class='last'><a href='page_id=29 '><span>Contact</span></a></li>
</ul>
</div>
