在 div 周围创建边框，top-border 通过 header，bottom-border 通过按钮

Question

我想创建此模型中显示的内容：

这是我目前拥有的：https://codepen.io/raney24/pen/VOmjBY

.header-border {
  width: 100%;
  margin-bottom: 10px;
  border-left: red solid 1px;
  border-right: red solid 1px;
  border-bottom: red solid 1px;
  .heading, .heading-subtitle {
    text-align: center;
  }
  .heading > span, .heading-subtitle > span {
    background-color: white;
    box-shadow: white 11px 0px 0px,
                white -13px 0px 0px;
    &:after {
      content: '';
      border-top: 1px solid red;
      height: 1px;
      width: 100%;
      display: block;
      position: relative;
      top: -20px;
      z-index: -1;
    }
  }
  .heading-subtitle > span {
    &:after {
      top: -13px;
    }
  }
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>

<div class="container">
  <div class="row">
    <div class="header-border">
      <h2 class="heading"><span>Learn More About What We Do</span></h2>
      <div class="col-sm-4">
        <div class="header-border">
          <h4 class="heading-subtitle"><span>Coding School</span></h4>
          <p>Awesome Inc U is our coding school. It is for both adults and children. We have taught over 1500 people to code with us.</p>
           <div class="text-center">
             <a class="btn btn-sm btn-primary" href="#">Read More</a>
          </div>
        </div>
      </div>
    </div>
  </div> <!-- row-->
</div><!-- container -->

我不确定如何将边框向下移动，以免超出我的 header 边框。也许我的做法不对，如果是这样，请告诉我您的想法。

我愿意使用 JavaScript/JQuery，但希望尽可能避免使用它。

删除了 :after css 并使用 margin: -20px 将 header 移到了顶部检查下方 link

.header-border {
  width: 100%;
  margin-bottom: 10px;
  border: red solid 1px;
  
  .heading, .heading-subtitle {
    text-align: center;
    margin-top: -20px
  }
 
 .heading > span, .heading-subtitle > span {
    background-color: white;
    box-shadow: white 11px 0px 0px,
                white -13px 0px 0px;
  }
  .heading-subtitle > span {
    &:after {
      top: -13px;

  }
}
