Question

我正在使用Bootstrap Card，并且在页脚中有两个按钮。我需要做的是将一个按钮对准绝对中心，并将另一个较小的按钮对准页脚的左侧。并且两个按钮都应该在垂直方向上居中对齐。

这是我的代码：

<div class="card">
    <div class="card-header">Header</div>
    <div class="card-body">Content</div> 
    <div class="card-footer">      
      <div class="btn-wrapper text-center">
        <a class="btn btn-secondary text-dark btn-sm">Remove</a> 
        <a class="btn btn-warning" style="">Next</a>
      </div>
    </div>
  </div>

这会将两张卡都对准中心。但是我需要“下一步”按钮位于中间，而“删除”按钮位于左侧。我该怎么办？

这是它的jsbin：https://jsbin.com/vesobayuci/1/edit?html,js,output

Answer 1

检查更新的JSBIN

.remove-btn {
  position: absolute;
  top: 50%;
  left: 0;
  transform: translateY(-50%);
}

.btn-wrapper {
  position: relative;
}

Answer 2

您可以像这样绝对定位它们

.card-footer .btn-wrapper{
  position: relative;
  min-height: 40px;
}

.card-footer .btn-wrapper .btn{
  position: absolute;
  top: 50%;
}

.card-footer .btn-wrapper .btn-warning{
  left: 50%;
  transform: translate(-50%, -50%);
}

.card-footer .btn-wrapper .btn-secondary{
  left: 0;
  transform: translate(0, -50%);
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<div class="container">
  <h2>Card Header and Footer</h2>
  <div class="card">
    <div class="card-header">Header</div>
    <div class="card-body">Content</div> 
    <div class="card-footer">      
      <div class="btn-wrapper text-center">
        <a class="btn btn-secondary pull-left text-dark btn-sm">Remove</a> 
        <a class="btn btn-warning" style="">Next</a>
      </div>
    </div>
  </div>
</div>

Answer 3

您可以使用transform属性和Bootstrap 4类完成此操作

.btn-warning {
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
}
