我如何调整这些卡，使其能够使用 Boostrap 4 做出响应？

如何让每个 row 显示 4 张卡片，当然，如果屏幕尺寸发生变化，则使它们堆叠起来。理想情况下，它们之间应该有一些空间。我已经尝试了我能研究的所有可能的组合。

#cardsContainer {
    display: flex;
    flex-wrap: wrap;
    justify-content: space-between;
    overflow-y: scroll;
    overflow: hidden;
    height: 1200px;
  }

  .card {
    display: flex;
    flex-wrap: wrap;
    justify-content: space-between;
    margin-bottom: 16px;
    width: calc(25% - 16px);
    padding-bottom: 10px;
    font-size: 12px;
    border-radius: 5px !important;
    flex-basis: 25%;
    outline-width: 0px;
    box-shadow: rgba(0, 0, 0, 0.24) 0px 3px 8px;
    outline: none;
    border: none;
    border-radius: 7px;
  }

  /* Remove extra left and right margins, due to padding */
  .row {
    margin: 0 -5px;
  }

  /* Clear floats after the columns */
  .row:after {
    content: "";
    display: table;
    clear: both;
  }

  @media only screen and (max-width: 767px) {
    .card {
      width: 100%;
      margin-bottom: 10px;
    }
  }

    请阅读有关响应式类的引导文档 ，我在此代码中使用了它们 (col-md-6)，以便从平板电脑开始显示两张卡，而在较大的屏幕上显示 4 张卡 (col-xl-3)

    诗。我清理了代码并添加了元视口，这对于移动查看很重要！

    #cardsContainer {
    display: flex;
    flex-wrap: wrap;
    justify-content: space-between;
    overflow-y: scroll;
    overflow: hidden;
    /*height: 1000px; WHY?*/
  }

  .card {;
    font-size: 12px;
    border-radius: 5px !important;
    flex-basis: 25%;
    box-shadow: rgba(0, 0, 0, 0.24) 0px 3px 8px;
    outline: none;
    border: none;
    border-radius: 7px;
    flex-direction: inherit!important;
  }

  /* .row {
    margin: 0 -5px;
  }
  .row:after {
    content: "";
    display: table;
    clear: both;
  } */

  @media only screen and (max-width: 767px) {
    .card {
      width: 100%;
      margin-bottom: 10px;
    }
  }
    

  
    
    
    

    
    

    Hello, world!
