从小断点内的按钮混合继承样式

Question

有没有办法让我只能在小的唯一断点中设置$expand并从上面继承$background和$background悬停？

&__close {
    @include button($background: $success-color, $background-hover: auto);
    @include breakpoint(small only) {
        @include button($background: $success-color, $background-hover: auto, $expand: true);
    }
}

将

button()参数默认为示例中的某些值是否是一种可能的"中间方法"？然后，您可以重新排列参数的顺序，并且仅覆盖$expand值，如下所示：

// @mixin button()
@mixin button( $expand: false, $background: $success-color, $background-hover: auto ) {
    // All the button stuff
}

// Your selector
&__close {
    @include button();
    @include breakpoint(small only) {
        @include button($expand: true);
    }
}
