有没有办法将Bootstraps 4 beta复选框大小更改为更大的？

我几乎尝试改变风格,但这不起作用.

谢谢!

我想知道如何在这个给定的例子中更改Bootstraps 4复选框背景颜色.

非常感谢!

<div class="custom-control form-control-lg custom-checkbox">  
    <input type="checkbox" class="custom-control-input" id="customCheck1">

我想知道如何更改Bootstraps单选按钮背景颜色和填充颜色？

<div class="form-check">
  <input class="form-check-input" type="radio" name="radio" id="radio1" value="option1">
  <label class="form-check-label" for="radio1"> radio label
  </label>
</div>

有什么方法可以在折叠面板时向Bootstrap4手风琴添加活动类？

我可以看到面板合拢时没有活动类添加到卡头中。

非常感谢！

下面的手风琴代码

**<div id="accordion" role="tablist">  
  <div class="card">  
    <div class="card-header" role="tab" id="headingOne">  
      <h5 class="mb-0">  
        <a data-toggle="collapse" href="#collapseOne" role="button" aria-expanded="true" aria-controls="collapseOne">  
          Collapsible Group Item #1  
        </a>  
      </h5>  
    </div>  

    <div id="collapseOne" class="collapse show" role="tabpanel" aria-labelledby="headingOne" data-parent="#accordion">
