Validation states
To inform users whether the entered value is correct or not, use either of the validation states. Thanks to that, users will immediately know which form elements they need to correct and, if the state displays as invalid, why the value is incorrect.
Validation states
To inform users whether the entered value is correct or not, use either of the validation states. Thanks to that, users will immediately know which form elements they need to correct and, if the state displays as invalid, why the value is incorrect.
To apply the validation state to the form control, use the .is-valid and .is-invalid classes.
Validation feedback
To provide users with additional information about the validation state, you can use the .valid-feedback and .invalid-feedback classes.
<input type="text" class="form-control is-valid" placeholder="Valid State..." />
<div class="valid-feedback">Looks good!</div>
This is how it works in the example below:
You can also use the .valid-feedback to provide users with positive feedback.
Subtle validation states
If you prefer a more subtle manner of informing users of the input control validation state, you can use tick and cross symbols and resign from colored control frames and the validation feedback.
To do this, use the .is-valid-lite and .is-invalid-lite classes.
<input type="text" class="form-control is-valid is-valid-lite" placeholder="Valid State..." />
Look how it works in the example below:
