推荐答案

您可以使用以下CSS在未选中时将其设置为红色，在选中时将其设置为黑色

you can use the following css to make it red when it is not checked, and black when it is checked

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

可以通过以下代码更改箭头的颜色

The color of the arrow can be changed by the following code

.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");
}

此代码将使刻度线变成红色，您可以通过将fill='red'值更改为您选择的颜色来更改颜色.

this code will make the tick red, you can change the color by changing the fill='red' value to a color of your choice.

注意，如果指定RGB颜色，例如. #444444使用％23作为哈希值，例如. ％23444444

Note, if specifying RGB color, eg. #444444 use %23 for the hash, eg. %23444444

或者您也可以使用任何喜欢的图像.

Or you could use any image you like instead.

@cprcrack发出请求后，添加了焦点颜色(粉红色)
