html - 如何使用 HTML 和 CSS 将现有列表元素放置在时间轴上？

我正在尝试构建一个类似于下图所示的时间轴: Example Timeline 我遇到的困难是构建时间线的底部，其中图标由一条线连接，以及将三 Angular 形添加到每个事件的底部。这是目前我的代码:

.navbar {
  margin-bottom: 0px;
}

.jumbotron {
  margin-bottom: 0px;
}

#timeline {
  list-style: none;
  white-space: nowrap;
  overflow: auto;
  padding-left: 0;
}

#timeline li {
  display: inline-block;
  padding: 1.5%;
  border: 1px solid #c0c0c0;
  border-radius: 5px;
  box-shadow: 1px 1px 6px #757677;
  margin-top: 2%;
  text-align: center;
  padding-bottom: 0;
  width: 45%;
}

#timeline li+li {
  margin-left: 2%;
}

#timeline li h3,
#timeline li em {
  display: block;
}

#timeline_header {
  padding-left: 0;
}

hr {
  width: 100%;
}

#triangle {
  width: 0;
  height: 0;
  border-left: 20px solid transparent;
  border-right: 20px solid transparent;
  border-top: 20px solid #757677;
  display: inline-block;
}

我列表中的第一个列表元素是我尝试添加一个三 Angular 形和一个图标，但我不知道如何将三 Angular 形定位在底部边框上，以及如何将图标直接定位在三 Angular 形下方，在图标之间使用水平线或其他线。

最佳答案

三 Angular 形被应用为一个伪元素::after。图像与 block 对齐 - 操作起来会容易得多。将 ScrollView 固定为仅在 X 轴上滚动，而不是在 Y 轴上滚动。该线是 ScrollView 外部的对象，否则它的长度将限制在可见区域并随 View 向左滚动。

.navbar {
  margin-bottom: 0px;
}

.jumbotron {
  margin-bottom: 0px;
}

#timeline {
  list-style: none;
  padding-left: 0;
  padding-top: 40px;
  padding-bottom: 60px;
  position: relative;
}

#timeline_border {
  position: relative;
  top: -123px;
  display: block;
  width: 100%;
  height: 1px;
  border-top: 2px solid #ccc;
  z-index: -1;
}

#timeline li {
  display: inline-block;
  padding: 1.5%;
  border: 1px solid #c0c0c0;
  border-radius: 5px;
  box-shadow: 1px 1px 6px #757677;
  margin-top: 2%;
  text-align: center;
  padding-bottom: 0;
  width: 45%;
  position: relative;
}

#timeline > li:after {
  position: absolute;
  bottom: -20px;
  left: 40px;
  width: 0;
  height: 0;
  border-left: 20px solid transparent;
  border-right: 20px solid transparent;
  border-top: 20px solid #757677;
  display: block;
  content: "";
}

#timeline li+li {
  margin-left: 2%;
}

#timeline li h3,
#timeline li em {
  display: block;
}

#timeline_header {
  padding-left: 0;
}

hr {
  width: 100%;
}

#triangle {
  width: 0;
  height: 0;
  border-left: 20px solid transparent;
  border-right: 20px solid transparent;
  border-top: 20px solid #757677;
  display: inline-block;
}

.timeline_ruler {
  white-space: nowrap;
   overflow-x: scroll;
   overflow-y: visible;
   display: block;
   height: auto;
   padding-bottom: 100px;
  
}

.timeline_icon {
  width: 80px;
  height: 80px;
  position: absolute;
  bottom: -102px;
  left: 20px;
}
