我的按钮触发不起作用

Question

当我将鼠标悬停在按钮上时，背景会变为默认的浅蓝色背景，为什么我的触发器不会触发？

<Style TargetType="Button" x:Key="btnBase">
    <Setter Property="OverridesDefaultStyle" Value="True"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Button Name="Button"
                        FontFamily="/Resources/Fonts/Source Sans Pro/#Source Sans Pro"
                        FontWeight="Bold"
                        FontSize="15"
                        BorderThickness="2"
                        Padding="14,3,14,3"
                        Foreground="{DynamicResource btnBaseForegroundColor}"
                        BorderBrush="{DynamicResource btnBaseBorderBrushColor}"
                        Background="{DynamicResource btnBaseBackgroundColor}">
                    <ContentPresenter/>
                </Button>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <Setter Property="Background" Value="Black"></Setter>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Background属性不用于为（标准）按钮的面部着色。

因此触发器有效，但它没有你期望的效果。
