                  <Button  Style="{StaticResource TitelButtonStyle}" >
                      <Grid>
                          <Image Source="添加.png" HorizontalAlignment="Left" RenderOptions.BitmapScalingMode="Fant" />
                          <TextBlock Margin="0,1,0,0" Foreground="White" Text="添加" HorizontalAlignment="Right" Width="28 "  />
                      </Grid>
                  </Button>
                  <Grid Width="1" Height="20" Background="White"  Opacity="0.5"  Margin="10,0,0,0"/>
                  <!--选项按钮-->
                  <Button  Style="{StaticResource TitelButtonStyle}" >
                      <Grid>
                          <Image Source="齿轮.png" HorizontalAlignment="Left" RenderOptions.BitmapScalingMode="Fant" />
                          <TextBlock Margin="0,1,0,0" Text="选项" HorizontalAlignment="Right" Width="28 "  />
                      </Grid>
                  </Button>
                  <Grid Width="1" Height="20" Background="White" Opacity="0.5"  Margin="10,0,0,0"/>
                  <!--关闭按钮-->
                  <Button Style="{StaticResource CloseButton}">
                      <Grid  Height="17"   Width="35">
                          <Image Source="关闭.png"  RenderOptions.BitmapScalingMode="Fant" />
                      </Grid>
                  </Button>
              </StackPanel>

样式如下：

<Style x:Key="CloseButton" TargetType="Button">
            <Setter Property="Opacity" Value="0.5"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Border Background="Transparent" BorderThickness="0" >
                            <ContentControl  Height="30"   Width="35" HorizontalAlignment="Center" VerticalAlignment="Center"  Content="{TemplateBinding Content}" Background="{TemplateBinding Background}"  />
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Background" Value="#ff0000"/>
                    <Setter Property="Opacity" Value="1" />
                </Trigger>
            </Style.Triggers>
        </Style>

关闭按钮应用的样式中，鼠标悬停触发器更改了两个属性，Opacity更改了可以生效，Background变更却没效果，求大神答疑
