SCSS方法

正确的方法是查看指南针设置 =>中的变量$custom-radio-indicator-icon-checked. \bootstrap\scss\_variables.scss.

SCSS approach

The right way to do this is by looking at the variable $custom-radio-indicator-icon-checked in the Compass setup => \bootstrap\scss\_variables.scss.

$custom-radio-indicator-icon-checked: str-replace(url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='-4 -4 8 8'%3E%3Ccircle r='3' fill='#{$custom-control-indicator-checked-color}'/%3E%3C/svg%3E"), "#", "%23") !default;

在这里您可以找到$custom-control-indicator-checked-color的用法，它使您可以选择更改颜色和背景色的选项.

Here you can find the use of $custom-control-indicator-checked-color which points you to the option(s) of changing color and background-color.

$custom-control-indicator-checked-color: $component-active-color !default;
$custom-control-indicator-checked-bg: $component-active-bg !default;

因此，更改$component-active-color或$component-active-bg.

$component-active-color: $white !default;
$component-active-bg: theme-color("primary") !default;

因此，您可以直接在变量内部或在组件级别更改颜色，以更改以下组件的所有指示符:

So you can change the color directly inside the variable or on component level to change all indicators of the following components:

• 自定义复选框
• 自定义广播
• 下拉列表
• nav-pills
• 分页
• 列表组

现在让我们假设您没有SCSS设置，而您只是想通过CSS覆盖颜色.您必须找到关联标签的伪类:after.

Now let's assume you don't have a SCSS setup and you're simply trying to override the color by CSS. You'll have to find the associated label's pseudo class :after.

.custom-radio .custom-control-input:checked~.custom-control-label::after {
    background-image: url(data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='-4 -4 8 8'%3e%3ccircle r='3' fill='%23fff'/%3e%3c/svg%3e);
}

在这里您正在寻找fill属性.井号(#)替换为%23.除此之外，它是一个十六进制值.那是为了圈子！

Here you're looking for the fill property. The hash sign (#) was replaced by %23. Other than that it's a hexadecimal value. That's for the circle!

为复选框本身更改border-color和background-color是在伪类:before上定义的:

Changing the border-color and background-color for the checkbox itself is defined on the pseudo class :before:

.custom-control-input.is-valid:checked~.custom-control-label::before, 
.was-validated .custom-control-input:valid:checked~.custom-control-label::before {
    border-color: #34ce57;
    background-color: #34ce57;
}

请注意，这些选择器还需要额外权重(验证，状态检查与否)以使其起作用.

Please note there's some additional weight (validation, state checked or not) to these selectors to make it work.
