Blu*_*nch 11 css checkbox bootstrap-4
我不知道如何更改此 Bootstrap 4 切换开关的“选中”背景颜色。它使用额外的库来切换深色和浅色模式 \xe2\x80\x93 Here on github \xe2\x80\x93 但这是有效的。我想要做的就是更改活动复选框的背景颜色,默认情况下为蓝色。Bootstrap CSS 默认为蓝色吗?这个答案更改 Bootstrap 4 复选框背景颜色对我不起作用;它更改了未选中的颜色,但我无法从中 grep 如何更改选中的颜色。

您可以简单地更改所有可能影响颜色的属性,例如
.custom-control-input:checked,.custom-control-label::before,.custom-control-input:active和.custom-control-input:focus
但你必须注意更改,.custom-control-input::after因为它会破坏切换开关内的指针
.custom-control-input:focus~.custom-control-label::before {
border-color: red !important;
box-shadow: 0 0 0 0.2rem rgba(255, 47, 69, 0.25) !important;
}
.custom-control-input:checked~.custom-control-label::before {
border-color: red !important;
background-color: red !important;
}
.custom-control-input:active~.custom-control-label::before {
background-color: red !important;
border-color: red !important;
}
.custom-control-input:focus:not(:checked)~.custom-control-label::before {
border-color: red !important;
}
.custom-control-input-green:not(:disabled):active~.custom-control-label::before {
background-color: red !important;
border-color: red !important;

只需将其添加到您的 css 文件中,或将其添加到<style>...之间的 html 文件</style>中,即可更改开关的背景颜色 - 它还会删除蓝色圆圈和阴影。=]
