我想知道如何在这个给定的示例中更改引导4复选框的背景色

<style>  
.custom-control-label::before,   
.custom-control-label::after {  
top: .8rem;  
width: 1.25rem;  
height: 1.25rem;  
}  
</style>  


<div class="custom-control form-control-lg custom-checkbox">  
    <input type="checkbox" class="custom-control-input" id="customCheck1">  
    <label class="custom-control-label" for="customCheck1">Check this custom checkbox</label>  
</div>


.自定义控件标签：：之前，
.custom控件标签：：在{
顶部：.8rem；
宽度：1.25雷姆；
高度：1.25雷姆；
}  
选中此自定义复选框

您可以使用以下css使其在未选中时为红色，在选中时为黑色

.custom-control-label:before{
  background-color:red;
}
.custom-checkbox .custom-control-input:checked~.custom-control-label::before{
  background-color:black;
}

箭头的颜色可以通过以下代码更改

.custom-checkbox .custom-control-input:checked~.custom-control-label::after{
  background-image:url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 8 8'%3E%3Cpath fill='red' d='M6.564.75l-3.59 3.612-1.538-1.55L0 4.26 2.974 7.25 8 2.193z'/%3E%3C/svg%3E");
}

此代码将使勾号变为红色，您可以通过将

fill='red'

值更改为您选择的颜色来更改颜色

编辑：注意，如果指定RGB颜色，例如#444444，请使用%23作为哈希，例如%2344444

或者你可以用任何你喜欢的图片来代替

我想在这里添加一个答案，这是knetsi答案的一个更简单、更通用的版本，适用于那些可能不想根据

：checked

伪类改变颜色的人

我只是想定义一个类

my error

，我可以将其添加或删除到复选框中以更改其颜色，在本例中，可以反映错误条件。无论复选框是否选中，颜色都保持不变

下面是它在代码中的外观：

<style>
  .custom-checkbox .custom-control-input.my-error~.custom-control-label::before{
    background-color:orangered;
  }
</style>

<div class="custom-control custom-checkbox">
  <input type="checkbox" class="custom-control-input my-error" id="customCheck1">
  <label class="custom-control-label" for="customCheck1">Check this custom checkbox</label>
</div>


.custom复选框。自定义控件输入。我的错误~。自定义控件标签：：before{
背景颜色：橙色；
}
选中此自定义复选框

甜美但如何更改内部图标的颜色？添加了css，您必须使用它才能更改勾号图标按住鼠标单击时显示的浅蓝色是什么？@shaneparsons更新了代码段，现在应该显示为绿色。聚焦时周围显示的浅蓝色阴影如何？
