如何通过此流程图中的决策框获取流线？

Question

我在 HTML 和 CSS 中创建了一个流程图，其中我使用了必须从中做出两个决定的决策框。一个在下面，但是副线流再次重定向到决策框中答案 'no' 流程图中的第一个框。那么如何在流程图的第一个框中添加一行决策框呢？

#no1 {
  width:300px;
  height:60px;
  margin:auto;
}
#no1 a {
  height:60px;
}
#line1{
  font-size:0;
  width:1px;
  height:40px;
  color:#fff;
  background-color:#000;
  margin:auto;
}
.diamond {
  position: relative;
  height: 190px;
  width: 190px;
  line-height: 200px;
  text-align: center;
  font-size: 20px;
  margin: auto;
  margin-left: 0%;
  display: inline-block;
}
.diamond:before {
  position: absolute;
  content: '';
  top: 0px;
  left: 0px;
  height: 100%;
  background-color: #4286f4;  
  width: 100%;
  margin: auto;
  transform: rotateX(45deg) rotateZ(45deg);
  box-shadow: 0px 0px 12px gray;
  display: inline-block;
}
.diamond-inner {
  width: 180px;
  height: 180px;
  position: relative;
  margin: auto;
  font: 19px Helvetica, Arial, Times;
  font-weight:bold;
  color: white;
  margin: auto;
  margin-top: 60px;
  display: inline-block;
  white-space: normal;
}

<div id="flow_container">
  <div id="no1"><%= button_to A, usemap="#", :method => "get", 
   disabled: true, class: "flowchartButtonBlue" %></div>
  <div id="line1"></div>

  <div id="no1"><%= button_to B, usemap="#", :method => "get", 
   disabled: true, class: "flowchartButtonBlue" %></div>               
  <div id="line1"></div>

  <div id="no1"><%= button_to C, usemap="#", :method => "get", 
   disabled: true, class: "flowchartButtonBlue" %></div>
  <div id="line1"></div>

  <div class='diamond'>
    <div class="diamond-inner">
      <%= Decision %>
    </div>
  </div>
  <div id="line1"></div>            

  <div id="no1"><%= button_to D, usemap="#", :method => "get", \
   class: "flowchartButtonOval" %></div>
 </div>

我尝试了很多方法在 HTML 和 CSS 表格中添加行，但它们对齐得不好。

我提供了我使用的所有必需代码。请尝试或只是与我分享一些代码链接，其中 HTML 和 CSS 中的流程图是使用带有流程线的决策框创建的。

我已经使用伪类来实现它。希望能帮助到你。谢谢
