我想将 Bootstrap 4 手风琴卡中不同 div 的图像相互对齐

问题描述

我的 Bootstrap 4 Accordion Card 的每个标题都有一个箭头图像。我的目标是让它们在卡片的右边缘（但仍在卡片的边界内）排列在一起。到目前为止，我尝试过的所有操作要么将箭头从卡片中推出，要么使它们位于标题的其余部分下方。

我尝试了 justify-content、align-content 和 align-items，但都没有奏效。任何有关如何实现这一目标的提示将不胜感激。下面是它目前的样子。

<div class="card">
      <h3> FAQ </h3>
    <div class="card-header" id="headingOne">
      <h5 class="mb-0">
        <button class="btn" data-toggle="collapse" data-target="#collapSEOne" aria-expanded="true" aria-controls="collapSEOne"> 
         How many team members can I invite? <img src="images/icon-arrow-down.svg" class="arrow"> 
        </button>
      </h5>
    </div>

    <div id="collapSEOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordion">
      <div class="card-body">
         You can invite up to 2 additional users on the Free plan. There is no limit on 
  team members for the Premium plan.
      </div>
    </div>
  </div>

#accordion{
      
      width:30%;
      float: right;
      position:relative;
      top: 300px;
      right: 900px;
      align-content: center;
      font-family: 'Kumbh Sans',sans-serif;
      
      
  }

  .card-header{
      
      background-color: white;
      clear: both;
    
      
  }
  
  .arrow{
      
      
  }
  
  button{
      position:relative;
      left:-32px;
  
  }

解决方法

我生成了一个示例以获得与 Bootstrap 4 相同的行为，并将您的箭头 <img> 移动到 <h5> 标记的内部。之后，float:right 属性将元素拉到右侧。

.xl {
  width:100%; 
  border: solid 1px #333;
}

#accordion{
  margin-left:30px;
  width:60%;          
}
  
.arrow{
  width:36px;
  height: auto;
  float:right;
}

您可以通过将 <h5> 元素放入一个 flex 行并使用 justify-content 属性和 space-between 来实现。

示例

HTML：

<div class="card">
    <h3> FAQ </h3>
    <div class="card-header" id="headingOne">
      <h5 class="mb-0">
        <button class="btn" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne"> 
         How many team members can I invite?
        </button>
        v
      </h5>
    </div>

    <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordion">
      <div class="card-body">
        You can invite up to 2 additional users on the Free plan. There is no limit on 
        team members for the Premium plan.
      </div>
    </div>
</div>

CSS：

#accordion {      
    width:30%;
    float: right;
    position:relative;
    top: 300px;
    right: 900px;
    align-content: center;
    font-family: 'Kumbh Sans',sans-serif;
}

.card-header {
    background-color: white;
    clear: both;
}

.card-header h5 {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  justify-content: space-between;
}
  
button{
    position:relative;
    left:-32px;
}

我使用 V 而不是您的图像来可视化效果，但结果是一样的。

片段：

#accordion {      
    width:30%;
    float: right;
    position:relative;
    top: 300px;
    right: 900px;
    align-content: center;
    font-family: 'Kumbh Sans',sans-serif;
}

.card-header {
    background-color: white;
    clear: both;
}

.card-header h5 {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  justify-content: space-between;
}
  
button{
    position:relative;
    left:-32px;
}
