@description

|
|
|
Angular sets these CSS classes. It is up to your application to provide useful styling.
|
|
|
|
# CSS classes used by angular
|
|
|
|
* `ng-invalid`, `ng-valid`
|
|
- **Usage:** angular applies this class to an input widget element if that element's input does
|
|
not pass validation. (see {@link api/ng.directive:input input} directive).
|
|
|
|
* `ng-pristine`, `ng-dirty`
|
|
- **Usage:** angular {@link api/ng.directive:input input} directive applies `ng-pristine` class
|
|
to a new input widget element which did not have user interaction. Once the user interacts with
|
|
the input widget the class is changed to `ng-dirty`.
