复选框通过使用 class="form-check" 来确保标签和复选框有适当边距。
.form-check-label 类添加到标签元素，.form-check 容器内添加 .form-check-input 类来设置复选框的样式。
checked 属性用于设置默认选中的选项。

如果你想把复选框变成一个可切换的开关，可以在
.form-check
容器内使用
.form-switch
类:
<
div
class
=
"
form-check form-switch
"
>
<
input
class
=
"
form-check-input
"
type
=
"
checkbox
"
id
=
"
mySwitch
"
name
=
"
darkmode
"
value
=
"
yes
"
checked
>
<
label
class
=
"
form-check-label
"
for
=
"
mySwitch
"
>
Dark Mode
</
label

</
div
