调整页面大小时div会移动

Question

我正在尝试重新创建的网站上有一个时间轴，当我将窗口调整为移动设备时，div会分开。我离网站有点远，对于我需要做些什么才能做到这一点非常谨慎。时间线有图标（有自己的div）＆amp;一个图标背景（也有自己的div），但我想我需要将它们包裹在一个更大的div中以使这个工作，但不知道如何。

在调整大小之前和调整大小之后，请在此处查看图像：

了解图标如何与背景分离？

时间轴中每个项目的Html代码：

                    <div class="timeline_item">
                     <div class="timeline_time"><p><em>1 hr ago</em></p></div>
                     <div class="icon_background"></div>
                     <div class="timeline_icon "><i class="ss-icon">doc</i></div>
                     <div class="timeline_text"><p>You read the article </p> </div>                  
                    </div>

CSS：

.timeline_item {
 width: 100%;
 padding-bottom: 17%;
}

.timeline_item .timeline_time {
 float: left;
 width: 20%;
}

.timeline_item .timeline_icon {
 float: left;
 width: 1%;
 }

.timeline_item .timeline_text {
 float: left;
 width: 65%;
 padding-left: 3%;
}

.timeline_icon {
 margin-left: -4%;
 margin-top: 2.5%;
}

Answer 1

无法访问正确的Jsfiddle演示，这里有一个使用伪元素的HTML结构减少的建议。

您可以使用图标字体，精灵或任何我使用过单个字母的地方。

当然，这种布局方法有替代方案，包括浮点数和实际表格。其中一些将需要修复＆＃39;达到“平等高度”这是CSS表格的原生。

Answer 2

由于没有完整的html或css，这是一种移动的第一种方法，需要相当不错的css技能才能遵循，但它以合乎逻辑的方式开始，适用于小视口并且流畅地调整。最小宽度是较大视图端口的布局开始的位置。之前的样式是全局的（由所有视口大小共享）。

HTML - 移动设备的结构不同，然后在最小宽度调整位置：

<div class="timeline_wrapper">
 <div class="timeline_item">
  <div class="timeline_icon">
   <i class="your-icon"></i>
  </div>
  <div class="timeline_time">
   <p><em>1 hr ago</em></p>
  </div>
  <div class="timeline_text">
   <p>Lack of peppering one's sentences with gerunds.Lack of peppering one's sentences with gerunds. Lack of peppering one's sentences with gerunds. You read the article </p>
  </div>
 </div>
 <div class="timeline_item">
  <div class="timeline_icon">
   <i class="your-icon"></i>
  </div>
  <div class="timeline_time">
   <p><em>1 hr ago</em></p>

  <div class="timeline_text">
