bootstrap 移动时的网格

Question

在全屏模式下我不想使用 grid 我想显示 7 并且我想在移动设备中管理图像 2,2,2,1

我怎么能做这样的事情...

<div class="col-xs-6">
   <img src="banner1.png" alt="" class="banner-img">
</div>
<div class="col-xs-6">
   <img src="banner1.png" alt="" class="banner-img">
</div>

在我的 html 中看起来不错，但在移动时如何显示 2,2,2,1

<div class="container banner">
      <img src="banner1.png" alt="" class="banner-img">
      <img src="banner2.png" alt="" class="banner-img">
      <img src="banner3.png" alt="" class="banner-img">
      <img src="banner4.png" alt="" class="banner-img">
      <img src="banner5.png" alt="" class="banner-img">
      <img src=banner6.png" alt="" class="banner-img">
      <img src="banner7.png" alt="" class="banner-img">
    </div>

基本上你需要做的就是玩CSS。在 Css 中使用 @media 并为 移动屏幕 设置横幅宽度。下面是完整的工作示例：

.banner {
  background-color: red;
  text-align: center;
  vertical-align: middle;
  width: 100%;
  padding: 10px;
}

.banner-img {
  margin-top: 25px;
  margin-right: 5px;
  width: 100px;
  height: 100px;
}

@media only screen and (max-width: 500px) {
  .banner-img {
    width: 120px;
  }
}

<div class="banner">
  <div class="container banner">
    <img src="http://via.placeholder.com/50x50" alt="" class="banner-img">
    <img src="http://via.placeholder.com/50x50" alt="" class="banner-img">
    <img src="http://via.placeholder.com/50x50" alt="" class="banner-img">
    <img src="http://via.placeholder.com/50x50" alt="" class="banner-img">
    <img src="http://via.placeholder.com/50x50" alt="" class="banner-img">
    <img src="http://via.placeholder.com/50x50" alt="" class="banner-img">
    <img src="http://via.placeholder.com/50x50" alt="" class="banner-img">
  </div>
</div>

您可以根据屏幕尺寸调整横幅宽度。享受吧！
