  <p>I want to bind the Label 3 to the right border. I have no Idea how to do this.
  My Code:</p>
  
  <pre><code>import kivy
  
  from kivy.app import App
  from kivy.uix.label import Label
  
  from kivy.uix.boxlayout import BoxLayout
  from kivy.lang import Builder
  
  root = Builder.load_string('''
  Screen:
      BoxLayout:
          orientation:'vertical'
          Label:
              text: '1'
              font_size: self.height
              size_hint: (1.0, 0.17)
          Label:
              text: '2'
              font_size: self.height
              size_hint: (1.0, 0.83)
      Label:
          text: '3'
  ''')
  
  class MyApp(App):
      def build(self):
          root.size_hint = (1.0, 1.0)
          return root
  
  if __name__ == '__main__':
      MyApp().run()
  </code></pre>
