Have the validation state classes (such as .has-error) been removed from Bootstrap 5?

I've noticed that the validation state classes (.has-success, .has-warning, etc) seem to have been removed in bootstrap 5 as they are not working anymore and I can't find them in the bootstrap.css file.

Before, I could easily use these classes with a simple code snippet like the one below:

<div class="form-group row mb-3" [ngClass]="{ 'has-error': !addOperator.controls['code'].valid && addOperator.controls['code']?.touched }">
  <label for="code" class="col-sm-3 important col-form-label">
    Company Code
  </label>
  <div class="col-sm-9">
    <input formControlName="code" type="text" class="form-control" placeholder="Company Code" required="" maxlength="120" aria-required="true">
    <span *ngIf="!addOperator.controls['code'].valid && addOperator.controls['code']?.touched"
             class="help-block col-sm-offset-4">
        Field is required
    </span>
  </div>
</div>

Now, the code looks like this:

<div class="form-group row mb-3" >
  <label for="code" class="col-sm-3 important col-form-label" 
         [ngClass]="{'text-danger': !addOperator.controls['code'].valid &&
           addOperator.controls['code']?.touched }">
    Company Code
  </label>
  <div class="col-sm-9">
    <input formControlName="name" type="text"
           [ngClass]="{ 'is-invalid': !addOperator.controls['code'].valid && 
             addOperator.controls['code'].touched }" class="form-control" 
           placeholder="Company Code" required="" maxlength="120" aria-required="true">
    <span *ngIf="!addOperator.controls['code'].valid && addOperator.controls['code']?.touched"
          class="help-block col-sm-offset-4" [ngClass]="{ 'text-danger': !addOperator.controls['code'].valid && addOperator.controls['code'].touched }">
      Field is required
    </span>
  </div>
</div>

It can be quite time-consuming to update a large number of forms and inputs with this change.

Thank you in advance for any help, and apologies for any formatting issues as this is my first time posting here.

Answer №1

has-error is now referred to as is-invalid

has-success has been changed to is-valid

has-warning has been eliminated from the options.

Answer №2

The previous validation classes, specifically

.has-error, .has-warning, and .has-success
, have been deprecated starting from v4.

According to the migration guide:

The use of .has-error, .has-warning, and .has-success classes has been replaced with HTML5 form validation through CSS’s :invalid and :valid pseudo-classes.

In the v5 documentation, the functionality of validation classes is described as follows:

  • HTML form validation is now achieved through CSS’s :invalid and :valid pseudo-classes on elements like <input>, <select>, and <textarea>.
  • Bootstrap applies the :invalid and :valid styles within a parent .was-validated class, typically assigned to the form. This helps control when the validation styles are displayed, especially after form submission attempts.
  • To reset form styles after any dynamic submissions, such as AJAX, remove the .was-validated class from the form container.
  • For server-side validation, .is-invalid and .is-valid classes can be used instead of pseudo-classes without the need for a .was-validated parent class.

In Angular, CSS classes .ng-valid, .ng-invalid are automatically added to form controls based on their status, offering customization options for styling within your application. More information on different form control status classes can be found here.
