Question

我对制作流程步骤有疑问。它应该是这样的:http://imgur.com/a/fpMjy

我对这个“箭头”有疑问，如何使边框变成虚线？

如何在每个步骤上使用不同的颜色？

我有什么:

      .step > p {
        margin: 0;
      }
      
      .step {
        border: 1px solid #000;
        text-align: center;

        float: left;
        position: relative;
        background: #ebeef0;
      }
      
      .step:after,
      .step:before {
        content: " ";
        position: absolute;
        top: 0;

  .step > p {
    margin: 0;
  }
  .step {
    border: 1px dashed #000;
    text-align: center;
    padding: 10px 10px 10px 30px;
    min-width: 180px;
    float: left;
    position: relative;
    background: #ebeef0;
  }
  .step:after {
    content: "";
    position: absolute;
    top: 9px;
    right: -20px;
    width: 40px;
    transform: rotate(45deg);
    height: 40px;
    background-color: #ebeef0;
    border-top: 1px dashed black;
    border-right: 1px dashed black;
    transition: border-color 0.2s ease;
  }
  .actual-step {
    background: #cfd6d9;
  }
  .actual-step:after {
    background-color: #cfd6d9;
  }
  .step-description {
    font-size: 13px;
  }
  #step1:after {
    z-index: 2;
  }
  #step2:after {
    z-index: 4;
  }

<div class="row text-center">
  <div class="col-md-4 step actual-step" id="step1">
