In the current [Dynamic Context](https://reactjs.org/docs/context.html#dynamic-context) example, there are following issues 1. The `<Page>` and `<Section>` component definition is not provided in example code. It causes syntax issues and needs to be removed manually. 2. The `<ThemedButton>` component has background color style but no style for text color. 3. The default text of the `ThemedButton` component is not present due to which the default case on `app.js` file does not appear properly. ### Current state <img width="299" alt="Screenshot 2019-10-12 at 02 18 17" src="https://user-images.githubusercontent.com/5287100/66684303-629a3180-ec97-11e9-98d3-98be4e67c3f2.png"> ### After fix <img width="297" alt="Screenshot 2019-10-12 at 02 17 52" src="https://user-images.githubusercontent.com/5287100/66684302-629a3180-ec97-11e9-97c4-1d2dafdd2775.png">
