Question

我的水平菜单条形码一直存在问题。

此菜单栏可正确显示1366 x 768分辨率

但是在按下ctrl - 短按键

之后

当我使用ctrl缩小浏览器大小时 - 短按键我的菜单会降下来。我已经尝试使用em和px单位来解决这个问题，但它似乎没有解决问题。我想澄清一下，菜单栏必须与整个页面中的其他内容一致，并且应该针对包装器的整个960px设置进行扩展。我需要帮助来解决这个问题。

以下是我的源代码

HTML

<nav>
  <div class="nav_wrapper">
    <div class="menu_box">
      <div id='cssmenu'>
        <ul>
          <li><a href='index.php' class="active"><span>Home</span></a></li>
          <li><a href='#'><span>About Us</span></a></li>
          <li><a href='#'><span>Courses</span></a>
            <ul>
              <li><a href='index.php'>AGP Program</a></li>
              <li><a href='index.php'>Web Program</a></li>
            </ul>

Answer 1

这可以通过在包装元素上添加min-width来简单地解决，在这种情况下，我发现它在应用于“nav_wrapper”时效果更好。此外，当使用大于显示的元素时，在body元素中没有边距是好的，所以我也改变了它。

以下是我所做的更改

<强> CSS

body{
        margin: 0px;
    }
.nav_wrapper{
        min-width: 980px;
}
