Question

我有一个格式化问题，我遇到了一个模态。我是新手前端编码器，请原谅凌乱的代码。

现在我正在使用引导程序列和一张卡片来进行以下操作

PICTURE OF THE WEBSITE BECAUSE I DONT HAVE ENOUGH REPUTATION

问题是我无法让第二行向上移动到第一行附近。不确定哪种css元素在这种情况下有用。我要向上移动的元素是在代码中标记为“事物”和“第二行”的事物。

无论如何，这里是所涉及的代码：

<div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true" id="test">
  <div class="modal-dialog modal-lg" style="overflow-y:auto">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">ORDER SUMMARY</h5>
        <button class="close" type="button" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">×</span>
        </button>
      </div>
      <!-- start content -->
      <div class="container-fluid">
        <!-- FIRST ROW -->
        <!-- left column -->
        <div class="row" style="width: 100%">
            <div class="col-md-4" style = "width:0%; margin-right: 10%;"> ORDER DETAILS 
            <hr>  
             <!-- Order Number -->
                <div class="form-group" style = "margin-right: 10%;">
                  <label for="disabledTextInput">Disabled input</label>
                  <input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input" style= "display: inline">
                </div>
          </div>
          <!-- right column -->
          <div class="col-md-4" style="width:100%; margin-right:20%; height:20rem;" id = "order-summary"> ORDER SUMMARY
            <div class="card" style="width:17rem; height:24rem">
              <div class="card-body" style="width:100%" id="item-summary">                

              </div>
            </div>
          </div>
        </div> 
        <!-- SECOND ROW -->
        <div class = "row">
          <div class="col-md-4 ml-auto" style = "width:100%; margin-right: 20%; position:fixed;"> things   
            <hr>  
             <!-- Order Number -->
                <!-- <div class="form-group" style = "margin-right: 10%;">
                  <label for="disabledTextInput">Disabled input</label>
                  <input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input" style= "display: inline">
                </div>      
              -->
          </div> 
        </div> 


      </div>

CSS：

    .row {
    display: flex;
  }

  .col {
    flex: 50%;
  }

  @media screen and (max-width: 600px) {
    .column {
      width: 100%;
    }
    .modal-content {
      width: 29rem;
      height: 38;
      margin: auto;
    }
  }
  label{
     font-weight: bold;
  }

  #create-order-modal {
    width: 750px !important;
    margin: auto !important;
  }

  .modal-content {
    width: 35rem;
    height: 35rem;
    margin: auto;
  } 
  .container-fluid{
    display:inline;
  }

我确定我的问题有某种快速解决方案，但我似乎找不到解决方案。由于某些原因，第一行元素太大，但是我尚未制作任何会影响高度大小的CSS元素。

网格结构存在一些问题，更重要的是，您应该使用d-flex flex-clolumn和flex-grow-1而不是设置elements的高度。如果要更改模态的宽度，请更改modal-dialog的宽度。

我从外部modal移除了div，以使模态可见。如果您在项目中使用代码，则应添加它。
