Question

我正在尝试教自己如何建立时间轴并添加图像。我在W3上找到了这个。我想在每个文本容器的左/右添加图像，以显示文本内容。我尝试了很多尝试以使其正常工作，但是我并不完全理解。此代码中还有一些我还不完全了解的部分。我认为这会很有帮助，如果您可以将其分解成几段，请对每行代码的功能进行一些解释。但是我的主要问题是在文本容器旁边（左侧或右侧）添加图像。谢谢。

.timeline {
  position: relative;
  max-width: 1200px;
  margin: 0 auto;
}

.timeline::after {
  content: '';
  position: absolute;
  width: 6px;

  margin-left: -3px;

      <p>Lorem ipsum..</p>
    </div>
  </div>
  <div class="container right">

Answer 1

您可以使用<img>标签将图像添加到现有容器中。

<div class="container left">
   <div class="content">
    <h2>2017</h2>
    <p>Lorem ipsum..</p>
   </div>
   <img src="https://placehold.it/200x200" /> <!-- image tag inside the container -->
 </div>

我添加了以下其他CSS，并使用了CSS flexbox layout。

/* Newly added CSS begin*/
.container {
  display: flex; /*this makes the container flexbox layout*/
}
.container.left .content {
   order: 2; /* order changes the content order within container */
   margin-left: auto; /* pushes the left content box to extreme left */
}
 .container.right .content {
    margin-right: auto;
 }
.container img {
 margin: 0 20px;
}
/* Newly added CSS ends */

更新后的代码如下：

* {
  box-sizing: border-box;
}

body {
  background-color: #474e5d;
  font-family: Helvetica, sans-serif;
}

/* Newly added CSS begin*/
.container {
  display: flex;
}
.container.left .content {
    order: 2;
    margin-left: auto;
}
.container.right .content {
   margin-right: auto;
}
.container img {
  margin: 0 20px;
}
/* Newly added CSS ends */

.timeline {
  position: relative;
  max-width: 1200px;
  margin: 0 auto;
}

.timeline::after {
  content: '';
  position: absolute;
  width: 6px;
  background-color: white;
  top: 0;
  bottom: 0;
  left: 50%;
  margin-left: -3px;
}

.container {
  padding: 10px 40px;
  position: relative;
  background-color: inherit;
  width: 50%;
}

.container::after {
  content: '';

  width: 25px;
  height: 25px;
  right: -17px;
  background-color: white;
  border: 4px solid #FF9F55;

  border-radius: 50%;
  z-index: 1;
}

.left {
  left: 0;
}

.right {

}

.left::before {
