Question

问题是我在我的网站上放置了一个适合整个屏幕或页面的水平菜单栏，所以当我尝试调整大小并使菜单栏变小以使其大小与网站上的其他部分相同时，每次我放大和缩小页面，菜单栏与其他部分不成比例地调整大小。

要自行查看问题，请在http://thenativeisodrafts.tumblr.com查看我的网站，然后尝试放大和缩小页面。

非常感谢！

这是 CSS ：

#cssmenu ul {
    margin: 0;
    padding: 0;
}
#cssmenu li {
    margin: 0;
    padding: 0;
}
#cssmenu a {
    margin: 0px;
    padding: 0px;
}
#cssmenu ul {
    list-style: none;
}
#cssmenu a {
    text-decoration: none;
}
#cssmenu {

   <li class='has-sub '><a href='#'><span>Products</span></a>
      <ul>
         <li class='has-sub '><a href='#'><span>Product 1</span></a>
            <ul>
               <li><a href='#'><span>Sub Item</span></a></li>
               <li><a href='#'><span>Sub Item</span></a></li>
            </ul>
         </li>
         <li class='has-sub '><a href='#'><span>Product 2</span></a>
            <ul>

      </ul>
   </li>
   <li><a href='#'><span>About</span></a></li>
   <li><a href='#'><span>Contact</span></a></li>

Answer 1

问题是#cssmenu已声明position: absolute。删除它，你应该是金色的：

#cssmenu {
    height: 70px;
    background-color: #232323;
    border-bottom: 5px solid #CD2C23;
    border-top: 5px solid #CD2C23;
    // position: absolute; // Remove this
    // right: 241px; // And this
}

Answer 2

您可以删除cssmenu的内联css并将其添加到主css文件中。

 #cssmenu {
   height: 70px;
   background-color: rgb(35,35,35);
   border-bottom: 5px solid #cd2c23;
   border-top: 5px solid #cd2c23;
   width:940.5px;
   margin:auto;
   z-index: 1000;
 }
