wpf Styles in WPF Defining an implicit style
Example
An implicit style applies to all elements of a given type within scope. An implicit style can omit x:Key since it is implicitly the same as the style's TargetType property.
<StackPanel>
<StackPanel.Resources>
<Style TargetType="TextBlock">
<Setter Property="Background" Value="Yellow"/>
<Setter Property="FontWeight" Value="Bold"/>
</Style>
</StackPanel.Resources>
<TextBlock Text="Yellow and bold!" />
<TextBlock Text="Also yellow and bold!" />
<TextBlock Style="{x:Null}" Text="I'm not yellow or bold; I'm the control's default style!" />
</StackPanel>
