+## Styling and Data Binding
+
+OpenMaui supports the full MAUI styling and data binding infrastructure:
+
+### XAML Styles
+```xml
+<ContentPage.Resources>
+    <ResourceDictionary>
+        <Color x:Key="PrimaryColor">#5C6BC0</Color>
+        <Style TargetType="Button">
+            <Setter Property="BackgroundColor" Value="{StaticResource PrimaryColor}" />
+            <Setter Property="TextColor" Value="White" />
+        </Style>
+    </ResourceDictionary>
+</ContentPage.Resources>
+```
+
+### Data Binding
+```xml
+<Label Text="{Binding Title}" />
+<Entry Text="{Binding Username, Mode=TwoWay}" />
+<Button Command="{Binding SaveCommand}" IsEnabled="{Binding CanSave}" />
+```
+
+### Visual State Manager
+All interactive controls support VSM states: Normal, PointerOver, Pressed, Focused, Disabled.
+
+```xml
+<Button Text="Hover Me">
+    <VisualStateManager.VisualStateGroups>
+        <VisualStateGroup x:Name="CommonStates">
+            <VisualState x:Name="Normal">
+                <VisualState.Setters>
+                    <Setter Property="BackgroundColor" Value="#2196F3"/>
+                </VisualState.Setters>
+            </VisualState>
+            <VisualState x:Name="PointerOver">
+                <VisualState.Setters>
+                    <Setter Property="BackgroundColor" Value="#42A5F5"/>
+                </VisualState.Setters>
+            </VisualState>
+        </VisualStateGroup>
+    </VisualStateManager.VisualStateGroups>
+</Button>
+```
