    border-radius: 100px;
    text-align: center;

  }
  
  
  /* 菱形，长宽91.28 */
  .diamond {
    width: 80px;
    height: 80px;
    color: aliceblue;
    transform: rotate(45deg);
    background-color: rgb(249, 169, 100);
    position: absolute;
  }
   
  .diamond-text{
    width: 60px;
    margin-top: 10px;
    display: inline-block;
    transform: rotate(-45deg);
    text-align: center;

    border-right: 5px solid transparent;
    border-top: 10px solid black;

  }
  
  /* 折线箭头 */
  .arrow-horizontal-down {
    width: 180px;
    height: 2px;
    background-color: black;
    position: absolute;
    z-index: -1;
  }
  

  
  /* 横线 */
  .horizontal-line{
    width: 100px;
    height: 2px;
    background-color: black;
    position: absolute;
    z-index: -1;
  }

这个示例创建了一个简单的流程图，包括开始、执行步骤、检查条件、根据条件分支以及结束。流程图使用CSS进行样式设置，包括步骤框和箭头。
