This example shows how to animate changes to the thickness of a border by using the <xref:System.Windows.Media.Animation.ThicknessAnimation> class.  
  
## Example  
 The following example animates the thickness of a border by using <xref:System.Windows.Media.Animation.ThicknessAnimation>. The example uses the <xref:System.Windows.Controls.Border.BorderThickness%2A> property of <xref:System.Windows.Controls.Border>.
