AngularJS Bootstrap
La hoja de estilo preferida de AngularJS es Twitter Bootstrap, que actualmente es el framework front-end más popular.
Bootstrap
Puedes añadir Twitter Bootstrap a tu aplicación AngularJS. Puedes añadir el siguiente código en tu elemento <head>:
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">
Si el sitio está en China, se recomienda usar el Bootstrap de la biblioteca de recursos estáticos de Baidu. El código es el siguiente:
<link rel="stylesheet" href="//apps.bdimg.com/libs/bootstrap/3.3.4/css/bootstrap.min.css">
El siguiente es un ejemplo HTML completo que utiliza directivas de AngularJS y clases de Bootstrap.

Análisis de código JavaScript
| Propiedad del scope | Uso |
|---|---|
| $scope.fName | Variable del modelo (nombre del usuario) |
| $scope.lName | Variable del modelo (apellido del usuario) |
| $scope.passw1 | Variable del modelo (contraseña del usuario 1) |
| $scope.passw2 | Variable del modelo (contraseña del usuario 2) |
| $scope.users | Variable del modelo (array de usuarios) |
| $scope.edit | Se establece en true cuando el usuario hace clic en 'Crear usuario'. |
| $scope.error | Se establece en true si passw1 no es igual a passw2 |
| $scope.incomplete | Se establece en true si algún campo está vacío (length = 0) |
| $scope.editUser | Establecer variable del modelo |
| $scope.watch | Monitorear la variable del modelo |
| $scope.test | Validar los errores y la completitud de la variable del modelo |
