HTML/CSS 列表图像/元素符号上方/下方

Question

我有以下包含列表及其对齐方式的 HTML/CSS。我设法在 div 的每个 Angular 落获取列表元素，现在我想尝试将图像(基本上用作“列表点”)放在顶部和底部，因此顶部元素的图像居中在它们上方，底部元素在它们下方居中。有人可以帮我吗？

body {
  margin:0;
}
.container {
  display:flex;
  flex-wrap:wrap;    
  flex-direction:row;    
  height:100vh;
  background-color: beige;
}
.container > div {
  min-height: 100vh;
  border:1px solid black;
  box-sizing:border-box;
  background-color: inherit;
}
.half-width {
  width:50%;
}
.half-width > .half-width-content{
  position: relative;
  margin-top: 0;

  width: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
}
.list-div {
  position: relative;
  display: flex;
  justify-content: center;
  align-items: center;
  width: 75%;
    height: 75%;
}

.list-div ul {
  padding: 0;
  margin-top: 15%;
  width: 75%;
}

.list-div li {
  position: absolute;
}

.list-div li:nth-child(1){
