html - 使用 CSS 和 HTML 的时间轴指示器

Question

我正在尝试结合使用 CSS 和 HTML 重新创建此图像，但没有成功。请指教。

当前代码:

.lens-profile-timeline {
  list-style: none;
  padding: 0;
  margin: 60px 0 80px;
  border-bottom: 8px solid #39752c;
  position: relative;
}
.lens-profile-timeline li {
  position: absolute;
  width: 16px;
  height: 16px;
  border: 13px solid #39752c;
  border-radius: 16px;
  background: #fff;
  margin-top: -10px;
  margin-left: 20px;
  margin-right: 20px;
}
.lens-profile-timeline time,
.lens-profile-timeline p {
  left: -27px;
  top: -40px;
  position: absolute;
  width: 70px;
  text-align: center;
}
.lens-profile-timeline time {
  margin-top: 70px;
  font-size: 18px;
}
.lens-profile-timeline p {
  margin-top: -0px;
  font-size: 10px;
  line-height: 1.1;
}
.lens-profile-timeline p:after {
  content: "";
  height: 8px;
  border-left: 1px solid #39752c;
  position: absolute;
  bottom: -10px;
  left: 35px;
}

<div class="row">
  <div class="col-md-3">
  </div>

  <div class="col-md-6">
    <ol class="lens-profile-timeline point">
      <li style="left: 0;">

        <time>1970</time>

      </li>
      <li style="left: 45%;">
        <time datetime="2003-01-01">2003</time>

      </li>

      <li style="right: 0;">
        <time>2013</time>
        <p class="hidden">Current Year</p>
      </li>
    </ol>
  </div>
  <div class="col-md-3">
  </div>
</div>

上面表示当前用于生成图像的代码。但是，您会注意到缺少几个元素。

Answer 1

您可以结合使用伪元素、CSS 三 Angular 形和线性渐变。

1. linear-gradient(to right, #AFCB6D, #126A38); 将创建混合背景色效果。
2. 最后的三 Angular 形可以使用 CSS triangles concept 创建使用伪元素。
3. 指标也是用伪元素圆圈创建的。指示 rune 本可以在 content: "" 中指定，或者删除伪元素并在 div 中指定文本以实现更好的自定义。

不使用 CSS 内容的常规文本:

.timeline {
  width: 500px;
  height: 10px;
  margin: 20px;
  background: linear-gradient(to right, #AFCB6D, #126A38);
  position: relative;
  font-family: Roboto;
}
.timeline::before,
.timeline::after {
  content: " ";
  position: absolute;
  height: 0px;
  width: 0px;
  top: -5px;
}
.timeline::before {
  left: -20px;
  border: 10px solid #AFCB6D;
  border-color: transparent #AFCB6D transparent transparent;
}
.timeline::after {
  right: -20px;
  border: 10px solid #126A38;
  border-color: transparent transparent transparent #126A38;
}
.indicators {
  position: relative;
}
.indicator-1,
.indicator-2,
.indicator-3 {
  border: 5px solid #AFCB6D;
  background: white;
  border-radius: 50%;
  width: 10px;
  height: 10px;
  top: -5px;
  position: absolute;
}
.indicator-1 {
  left: 10px;
}
.indicator-2 {
  border-color: #5B9951;
  left: 240px;
}
.indicator-3 {
  border-color: #126A38;
  left: 475px;
}
.indicator-text {
  position: relative;
  top: 15px;
}
.indicator-1 .indicator-text {
  left: -20px;
}
.indicator-2 .indicator-text {
  left: -15px;
}
.indicator-3 .indicator-text {
  left: -10px;
}

<div class="timeline">
  <div class="indicators">
    <div class="indicator-1">
      <div class="indicator-text">Standard</div>
    </div>
    <div class="indicator-2">
      <div class="indicator-text">Better</div>
    </div>
    <div class="indicator-3">
      <div class="indicator-text">Best</div>
    </div>
  </div>
</div>

使用内容属性的标题:

.timeline {
  width: 500px;
  height: 10px;
  margin: 20px;
  background: linear-gradient(to right, #AFCB6D, #126A38);
  position: relative;
  font-family: Roboto;
}
.timeline::before,
.timeline::after {
  content: " ";
  position: absolute;
  height: 0px;
  width: 0px;
  top: -5px;
}
.timeline::before {
  left: -20px;
  border: 10px solid #AFCB6D;
  border-color: transparent #AFCB6D transparent transparent;
}
.timeline::after {
  right: -20px;
  border: 10px solid #126A38;
  border-color: transparent transparent transparent #126A38;
}
.indicator {
  border: 5px solid #5B9951;
  background: white;
  border-radius: 50%;
  width: 10px;
  height: 10px;
  margin: 0 auto;
  top: -5px;
  position: relative;
}
.indicator::after {
  content: "\a Best";
  white-space: pre;
  border: 5px solid #126A38;
  background: white;
  border-radius: 50%;
  width: 10px;
  height: 10px;
  top: -5px;
  left: 230px;
  position: absolute;
}
.indicator::before {
  content: "\a Standard";
  white-space: pre;
  border: 5px solid #AFCB6D;
  background: white;
  border-radius: 50%;
  width: 10px;
  height: 10px;
  top: -5px;
  left: -240px;
  position: absolute;
}
.spacer {
  margin-top: 20px;
}

<div class="timeline">
  <div class="indicator">
    <div class="spacer"></div>Better
  </div>
</div>
