Question

希望一切顺利，我通过媒体查询测试响应式网站（最大宽度为960px和480px），我怀疑为什么页面变成空白或白色背景而不是背景图像，也许它与基金会5有关溢出隐藏？覆盖基础文件？

如果我删除了头部标签下的Foundation的href链接，则背景图像会恢复正常。由于我是基金会的新手，有什么解决方案？

问题出在</nav>的位置。由于媒体查询，当屏幕足够小时，导航会折叠。但.bgImage包含在导航中，因此它也会折叠。改为：

<nav class="top-bar" data-topbar role="navigation">
  <ul class="title-area">
    <li class="name">
  <h1><a href="#">Mike Davis</a></h1>
</li>
  <!-- Remove the class "menu-icon" to get rid of menu icon. Take out "Menu" to just have icon alone -->
      <li class="toggle-topbar menu-icon"><a href="#"><span></span></a></li>
  </ul>

<!--Section wrap -->
<section class="topbar">
<ul class="topside-nav">
  <li><a href="#">Portfolio</a></li>
  <li><a href="#">Pictures</a></li>
  <li><a href="#">Map</a></li>
  <li><a href="#">Contact</a></li>
</ul>   
</section>    
</nav> <!--- ADD </nav> here -->
<!--Short Description -->
<div class="myDiv">
    <div class="bgImage" style="position: absolute; top: 90%; left: 0px;">
    <h1>Hello! I am Mike</h1>
    <p>I enjoy building websites for individuals and businesses!</p>    
  </div>
    </div>
<!---  DELETE THIS NAV </nav>  -->
</body>
</html>

现在你需要修复.bgImage的顶部填充/边距，但这应该可以解决图像消失的问题。

变化：

<div class="bgImage" style="position: absolute; top: 90%; left: 0px;">

为：

<div class="bgImage" style="position: absolute; top: 19%; left: 0px;">

应该做的伎俩。最好把它移到你的style.css上。
