调用display：none时菜单不会消失

Question

我的ipad /移动菜单类：（.vd-hide）仅用于在浏览器处于928PX时显示。但是，它显示的是整个时间。正如你在我的代码中看到的那样，我最初为它写了（display：none），但在928PX，我把它称为显示为（display：inline-block）。

当浏览器处于桌面大小时，为什么它会消失？

Answer 1

这是因为您将.vd-hide {display: inline-block}置于@media ... {}查询之外。

此部分已修复：

@media screen and (max-width: 928px) {
  .vd-grid-left-col {
    width: 100%;
  }
  .vd-grid-right-col {
    overflow: hidden;
    width: 100%;
    margin: 0;
    clear: both;
  }
  .vd-grid-right-col > div {
    width: 49%;
    box-sizing: border-box;
    margin: 0;
  }
  .vd-grid-right-col > div:first-child {
    margin-right:2%;
  }
  .vd-grid-xtra-box {
    float: left;
  }
  .vd-footer{
    margin-top: 20px;  
  }

  .vd-nav-wrapper ul li {
    display: none;
  }
  .vd-hide {
        display: inline-block;
  }
}
