需要将正常的复选框打勾更改为 bootstrap 复选框打勾

Question

我有 2 个复选框，其中一个是使用 Bootstrap 创建的，一个是正常的。我想将普通复选框显示为 bootstrap 勾选框。

下面是我的代码：

.custom-checkbox-input {
     position: relative;
     z-index: 1;
     display: block;
     min-height: 1.5rem;
     padding-left: 1.5rem;
}
 .custom-checkbox-input .form-check-input {
     width: 20px;
     height: 20px;
}
 .custom-checkbox-input .form-check-input::after {
     content: '';
     display: inline-block;
     width: 20px;
     height: 20px;
     border: solid 1px grey;
     border-radius: 2px;
}
 .custom-checkbox-input .form-check-input:checked::after {
     width: 20px;
     height: 20px;
     border: solid 1px red;
     content: '✔';
     background-color: red;
     color: white;
     text-align: center;
}
 .custom-checkbox-input .form-check-input .custom-color-grey::after {
     background-color: grey;
}
 .custom-checkbox-input .form-check-input .custom-color-white::after {
     background-color: white;
}

如果你想让两个复选框与刻度线保持一致，我的建议是使用字体很棒的图标。

.custom-checkbox-input {
     position: relative;
     z-index: 1;
     display: block;
     min-height: 1.5rem;
     padding-left: 1.5rem;
}
 .custom-checkbox-input .form-check-input {
     width: 20px;
     height: 20px;
}
 .custom-checkbox-input .form-check-input::after {
     content: '';
     display: inline-block;
     width: 20px;
     height: 20px;
     border: solid 1px grey;
     border-radius: 2px;
}
 .custom-checkbox-input .form-check-input:checked::after {
     width: 20px;
     height: 20px;
     border: solid 1px red;
     content: '\f00c';
     font-family: "Font Awesome 5 Free"; 
     font-weight:900;
     background-color: red;
     color: white;
     text-align: center;
     font-size:13px;
     position:relative;
     top:-2px;
     
}
 .custom-checkbox-input .form-check-input .custom-color-grey::after {
     background-color: grey;
}
 .custom-checkbox-input .form-check-input .custom-color-white::after {
     background-color: white;
}
