Validation
Provide valuable, actionable feedback to your users with HTML5 form validation, via browser default behaviors or custom styles and JavaScript.
Custom styles
For custom React Bootstrap form validation messages, you’ll need to add the novalidate attribute to your <Form> or <form> element
<form class="row g-3 needs-validation" novalidate>
<div class="col-md-4">
<label for="validationCustom01" class="form-label">First name</label>
<input type="text" class="form-control" id="validationCustom01" value="Mark" required>

</form>Form libraries and server-rendered styles
It's often beneficial (especially in React) to handle form validation via a library like Formik. In those cases, isValid and isInvalid props can be added to form controls to manually apply validation styles. Below is a quick example integrating with Formik .
<form class="row g-3">
<div class="col-md-4">
<label for="validationServer01" class="form-label">First name</label>
<input type="text" class="form-control is-valid" id="validationServer01" value="Mark" required>
<div class="valid-feedback">
Looks good!
</div>
</div>
<div class="col-md-4">
<label for="validationServer02" class="form-label">Last name</label>
<input type="text" class="form-control is-valid" id="validationServer02" value="Otto" required>
<div class="valid-feedback">

</div>

<div class="col-md-4">

<div class="input-group has-validation">
