html - 如何使用 CSS 显示时间轴

Question

我正在创建时间轴，但它没有显示我的设计输出。我必须在图像之后显示第一个 child ，在图像之前显示下一个 child ，并带有完整的下划线。我试过了，但我的下划线没有显示正确甚至图像显示不正确

你能帮我解决这个问题吗？我需要这样的输出。

.timeline ul li {
  list-style-type: none;
  position: relative;
  width: 6px;
  margin: 0 auto;
  padding-top: 50px;
 /* background: #fff;*/
 border-right: 2px solid #ff0000;
}
 
.timeline ul li::after {
  content: '';
  position: absolute;
  left: 50%;
  bottom: 0;
  transform: translateX(-50%);
  width: 30px;
  height: 30px;
  background: inherit;
}
.timeline ul li:nth-child(odd),
.timeline ul li:nth-child(even){
  width:50%;
  float:left;
  clear:right;
  text-align:right;
  position:relative;
}
.timeline ul li:nth-child(even){
  width:50%;
  float:right;
  clear:left;
  text-align:left;
  position:relative;
}
.timeline ul li:nth-child(odd):after,
.timeline ul li:nth-child(even):before{
background: url('https://image.flaticon.com/icons/png/512/67/67347.png') no-repeat;
width: 24px;
height: 20px;
background-size: 100% 100%;
}

<div class="timeline">
                  <ul>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                        <li><a href="">Lorem ipsum dolor sit amet, consectetu</a></li>
                  </ul>
            </div>

这不是完美的或动态的，但它会让您走上正确的道路。使用 nth-child(odd/even) 选择每隔一行

li:nth-child(odd) {    
float: left;
border-right: thick solid #ff0000;

margin: 0px;
padding-right: 20px;
background-image: url('https://image.flaticon.com/icons/png/512/67/67347.png');
background-repeat: no-repeat;
background-size: 20px 20px;
background-position-x: 254px;
background-position-y: 18px;
}
li:nth-child(even) {    
float: right;
border-left: thick solid #ff0000;
margin-right: 186px;
         
padding-left: 20px;
background-image: url('https://image.flaticon.com/icons/png/512/67/67347.png');
background-repeat: no-repeat;
background-size: 20px 20px;
background-position-y: 18px;    
}
ul{
list-style: none;
}
li{
padding: 20px 0 0 0;
}
div{
width: 777px;
}
img{
width: 20px;
}

<div class="timeline">
      <ul>                  
         <li>
             <a href="">Lorem ipsum dolor sit amet, consectetu</a>                         
         </li>  
            
         <li>                         
             <a href="">Lorem ipsum dolor sit amet, consectetu</a>   
         </li>    
             
         <li>
             <a href="">Lorem ipsum dolor sit amet, consectetu</a>                           
         </li>
            
         <li>                        
             <a href="">Lorem ipsum dolor sit amet, consectetu</a>                         
         </li>   
         
         <li>                         
             <a href="">Lorem ipsum dolor sit amet, consectetu</a>   
         </li>
     </ul>
</div>
