Bootstrap 5 单选切换按钮 btn-check 与 btn-sm 类

Question

我正在尝试使用 btn-check 类和 btn-sm 来获得更小的按钮，但它忽略了小类。我错过了什么还是有其他方法可以让按钮变小？

<div class="row g-2 mx-2 my-2">
  <div class="btn-group col-6" role="group">
    <input type="radio" class="btn-check btn-sm" name="option" id="option-1" value="yes">
    <label class="btn btn-outline-success" for="option-1">Yes</label>
    
    <input type="radio" class="btn-check btn-sm" name="option" id="option-2" value="na">
    <label class="btn btn-outline-secondary" for="option-2">I Don't Know</label>

    <input type="radio" class="btn-check btn-sm" name="option" id="option-3" value="no">
    <label class="btn btn-outline-danger" for="option-3">No</label>
  </div>
  </div>

Answer 1

给你...

1. 从

   btn-sm

   元素中删除

   <input>

   类。
2. 将

   btn-sm

   类添加到

   <div class="btn-group col-6" role="group">

   和所有三个

   <label>

   元素。

请参阅下面的片段。

<div class="row g-2 mx-2 my-2">
  <div class="btn-group col-6 btn-sm" role="group">
    <input type="radio" class="btn-check" name="option" id="option-1" value="yes" />
    <label class="btn btn-outline-success btn-sm" for="option-1">Yes</label>

    <input type="radio" class="btn-check" name="option" id="option-2" value="na" />
    <label class="btn btn-outline-secondary btn-sm" for="option-2">I Don't Know</label>

    <input type="radio" class="btn-check" name="option" id="option-3" value="no" />
    <label class="btn btn-outline-danger btn-sm" for="option-3">No</label>
  </div>
</div>

Answer 2

您也可以将 div 中的 btn-group 类更改为 btn-group-sm。

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"/>
    


<div class="row g-2 mx-2 my-2">
  <div class="btn-group-sm col-6" role="group">
    <input type="radio" class="btn-check" name="option" id="option-1" value="yes" />
    <label class="btn btn-outline-success" for="option-1">Yes</label>

    <input type="radio" class="btn-check" name="option" id="option-2" value="na" />
    <label class="btn btn-outline-secondary" for="option-2">I Don't Know</label>

    <input type="radio" class="btn-check" name="option" id="option-3" value="no" />
    <label class="btn btn-outline-danger" for="option-3">No</label>
  </div>
</div>
