解决方法

您的代码几乎是正确的，您只需要像这样将card-footer上移到card-img-overlay容器中即可。

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" rel="stylesheet" />

<div class="col-md-3">
  <div class="card">
    <img class="card-img" src="https://images.unsplash.com/photo-1523805009345-7448845a9e53?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=752&q=80" alt="...">
    <div class="card-img-overlay">
      <h5 class="card-title"></h5>
      <div class="card-footer text-center">
        <h6>
          Africa
        </h6>
        <h4>
          Kenya
        </h4>
      </div>
    </div>
  </div>
</div>

,

.card-footer:last-child {
    border-radius: 0!important;
}

.card-footer {
    padding: 0!important;
    background-color: unset!important;
    border-top: unset!important;
}

.text-center {
    color: #fff;
}

.card-img-overlay {
    display: flex;
    flex-direction: column;
    justify-content: flex-end;
    height: 100%;   
}

我认为您需要在卡片周围添加另一个div。该div必须具有类row
