图标未向右对齐

Question

我正在使用bootstrap手风琴，我想在链接的右边有一个箭头，但是使用text-right来使右边的文本对齐是行不通的。 你知道为什么吗？ 您还知道当用户单击时如何将超赞字体从<i class="fa fa-arrow-right"></i>切换为<i class="fa fa-arrow-down"></i>在链接中？

HTML：

<div class="container py-5">
  <div class="row">
    <div class="col">
      <div class="accordion" id="accordionExample">
        <div class="card">
          <div class="card-header" id="headingOne">
            <h5 class="mb-0">
              <a class="text-custom-blue-dark" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
                Title
              </a>
              <span class="ml-auto text-right"><i class="fa fa-arrow-right"></i></span>
            </h5>
          </div>

          <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
            <div class="card-body">

Answer 1

span元素默认为inline 。 因此它们占据了内容的确切宽度。 您可以改用div但是它将放在下一行。

最好的选择是使用定位或浮动元素。 但是我觉得最干净的是使用flex

.mb-0 {
  display: flex;
  justify-content: space-between;
}
