使用@media 仅屏幕实现移动视图以隐藏 div 的问题

Question

我试图在移动视图上隐藏 div id“tiled-map”，而 div id“map-wrapper”中的所有 3 个 div id（base-map、overlay-map、tiled-map）将显示在桌面视图中。

我正在使用 Bootstrap CSS。我还没有任何用于 div id "map-wrapper" 的特殊 CSS 类，但我在初始时将其宽度强制为 200%。但是，我想在移动视图上将其宽度修改为 100%——我在 Bootstrap 中创建了一段 CSS。我知道我为 div 类“mobile-hide”做的一些事情是多余的，我正在试验它。

部分代码如下所示。

HTML：

<meta name="viewport" content="width=device-width, initial-scale=1.0">

<div class="container">
    <div class="row">
        <div class="col-lg-6 col-md-6">
        <div id="map-wrapper" class="mobile-hide" style="width: 200%; height: 600px; position: relative;">
            <div id="base-map"></div>
            <div id="overlay-map"></div>
            <div id="tiled-map"></div>
        </div>
        </div>
    </div>
</div>

CSS：

@media only screen and (max-width: 480px) {
  #tiled-map {
    visibility: hidden !important;;
    display: none !important;
  }
  .mobile-hide {
    width: 100%;
    visibility: hidden !important;;
    display: none !important;
  }
}

我该如何解决这个问题？

Answer 1

看看这个小提琴。请注意，当您在媒体查询中将max-width 提高到大于您当前使用的屏幕的大小时，这些项目将消失。当max-width 减小到小于它占据的屏幕大小时，您将看到红色的 div。

请注意，我在编写会更改可见性的媒体查询之前为 div 设置了默认样式。您需要确定您编写的媒体查询将覆盖任何已设置的属性。
