javascript - 图标未右对齐

Question

我正在使用 bootstrap Accordion ，我想在链接的右边有一个箭头，但是用 text-right 将文本右对齐是行不通的。你知道为什么吗？您还知道如何切换 <i class="fa fa-arrow-right"></i> 中的超棒字体吗？至 <i class="fa fa-arrow-down"></i>当用户点击链接时？

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。所以它们占据了内容的确切宽度。您可以改用 div，但它会落在下一行。

您最好的选择是使用定位或 float 元素。但我觉得最干净的是使用 flex

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