I currently have a button on my website that triggers a form:
<button (click)="create()" *ngIf="data.new" [disabled]="!dataForm.valid" color="primary" mat-raised-button>
Go
</button>
Under specific conditions, this button disables all fields.
Is there a way to use CSS to style the form only when it is affected by the [disabled] attribute?
@Eudz provided a great approach to tackling the issue. However, if you want to apply a style globally, such as for an invalid input box, you can also use CSS targeting. Angular automatically adds classes to form inputs like ng-invalid, ng-valid, ng-pristine, etc.
You can then target these classes with CSS.
For instance:
input.ng-invalid {
border: 1px solid red;
}
A great example of customization is when you need to style an input element based on the validity of a form:
<input type="text" [class.border-danger]="!dataForm.valid">
Alternatively, you can do:
<input type="text" [class.border-danger]="dataForm.invalid">
The condition !dataForm.valid determines whether the button should be disabled.
