This is a learning project to show you how can be developed a radio buttons with ARIA. In the code there are the comparison between the classic mode (native input type="radio") and the button mode with the support of WAI-ARIA (those buttons work as radios and you can choose only 1 option per time).
All the code is tested with Karma/Jasmine and accessible, if you don't know what Accessibility is you can check my article: Introduction to Web Accessibility
Note: Take in consideration that when is possible use always the default native elements, you will get for free all the native element behaviour.
Run npm start to start the app. Navigate to http://localhost:4200/ and test the app with a browser and/or a screen reader.
Run ng test to run the app tests.
