在页面上居中下拉cssmenu

标签： html css

我找不到以此为中心的方法，其他搜索也没有帮助我。这是由css菜单生成的。

我尝试了一些我已经找到的东西，但没有任何效果。希望有人知道如何。

HTML 

<body>

<div id='cssmenu'>
<ul>
   <li><a href='#'>Home</a></li>
   <li class='active'><a href='#'>Products</a>
      <ul>
         <li><a href='#'>Product 1</a>
            <ul>
               <li><a href='#'>Sub Product</a></li>
               <li><a href='#'>Sub Product</a></li>
            </ul>
         </li>
         <li><a href='#'>Product 2</a>
            <ul>
               <li><a href='#'>Sub Product</a></li>
               <li><a href='#'>Sub Product</a></li>
            </ul>
         </li>
      </ul>
   </li>
   <li><a href='#'>About</a></li>
   <li><a href='#'>Contact</a></li>
</ul>
</div>

一种解决方案是更改以下内容：

#cssmenu #menu-button {
  margin: 0;
  padding: 0;
  border: 0;
  list-style: none;
  line-height: 1;
  display: inline-block;/*Change display to inline block*/
  position: relative;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  text-align: center;/*Add text-align center*/
}

#cssmenu {
  font-family: Montserrat, sans-serif;
  background: #333333;
  width: 100%;/*Add width 100%*/
}
