<Style TargetType="CheckBox" x:Key="Checkbox">
            <Setter Property="BorderThickness"          Value="2" />
            <Setter Property="VerticalAlignment"        Value="Top" />
            <Setter Property="Margin"                   Value="20,15,0,0" />

            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type CheckBox}">
                        <CheckBox  Background="{TemplateBinding Background}" >
                            <ContentPresenter  />
                        </CheckBox>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="Background" Value="Red"/>
                            </Trigger>
