html - Twitter 喜欢固定标题

Question

如何在页面顶部创建固定的标题，如 Twitter/Facebook？

我正在对此进行测试，但是当我调整浏览器大小时，整个设计都变形了

  <div id="head">
   <div id="logo">
    <a href="#"></a>
   </div>
   <div style="display:inline;">
    <input style="margin-top:3px;" class="searchbox" type="text"/>
   </div>
 <ul>
  <li>
   <a href="#" title="Home">Home</a> 
  <li>
  <li>
   <a href="#" title="Profile">Profile</a> 
  </li>
  <li>
   <a href="#" title="Profile">Actions</a> 
  </li>
  <li>
   <a href="#" title="Profile">Invite Friends</a> 
  </li>
 </ul>


</div>
<div id="content">
      </div>

风格

     html {
         height:100%; /* fix height to 100% for IE */
         max-height:100%; /* fix height for other browsers */
         padding:0; /*remove padding */
         margin:0; /* remove margins */

         background:#fff; /*color background - only works in IE */
         /* hide overflow:hidden from IE5/Mac */
         /* \*/
         overflow:hidden; /*get rid of scroll bars in IE */
         /* */
}

Answer 1

您的#head 元素需要有固定的定位才能使其 float 在顶部。这将使它始终保持在顶部。试试这个

#head {
     position:fixed;
     margin:0px;
     top:0px;
     left:0px;
     display:block;
     width:100%;
     height:40px;
     -moz-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.5);
     background:#333333;
     background: -moz-linear-gradient(center top , #736F6E, #111111) repeat scroll 0 0 transparent;
}
