How to Create Login Form in Bootstrap Modal

1. First of all, load the Bootstrap 4 CSS and Font Awesome CSS in the head section of your HTML page in order to create a login form modal popup.

<div class="container">
  <button type="button" class="btn btn-info btn-round" data-toggle="modal" data-target="#loginModal">
    Login
  </button>  
</div>

3. Similarly, create the HTML structure for login form and place it inside the Bootstrap modal’s markup.

<div class="modal fade" id="loginModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-dialog-centered" role="document">
    <div class="modal-content">
      <div class="modal-header border-bottom-0">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">×</span>
        </button>
      </div>
      <div class="modal-body">
        <div class="form-title text-center">
          <h4>Login</h4>
        </div>
        <div class="d-flex flex-column text-center">
          <form>
            <div class="form-group">
              <input type="email" class="form-control" id="email1"placeholder="Your email address...">
            </div>
            <div class="form-group">
              <input type="password" class="form-control" id="password1" placeholder="Your password...">
            </div>
            <button type="button" class="btn btn-info btn-block btn-round">Login</button>
          </form>
          
          <div class="text-center text-muted delimiter">or use a social network</div>
          <div class="d-flex justify-content-center social-buttons">
            <button type="button" class="btn btn-secondary btn-round" data-toggle="tooltip" data-placement="top" title="Twitter">
              <i class="fab fa-twitter"></i>
            </button>
            <button type="button" class="btn btn-secondary btn-round" data-toggle="tooltip" data-placement="top" title="Facebook">
              <i class="fab fa-facebook"></i>
            </button>
            <button type="button" class="btn btn-secondary btn-round" data-toggle="tooltip" data-placement="top" title="Linkedin">
              <i class="fab fa-linkedin"></i>
            </button>
        </div>
      </div>
    </div>
      <div class="modal-footer d-flex justify-content-center">
        <div class="signup-section">Not a member yet? <a href="#a" class="text-info"> Sign Up</a>.</div>
      </div>
  </div>
</div>

4. Style your modal login form with some additional CSS.

.container {
  padding: 2rem 0rem;
}

@media (min-width: 576px) {
  .modal-dialog {
    max-width: 400px;
  }
  .modal-dialog .modal-content {
    padding: 1rem;
  }
}
.modal-header .close {
  margin-top: -1.5rem;
}

.form-title {
  margin: -2rem 0rem 2rem;
}

.btn-round {
  border-radius: 3rem;
}

.delimiter {
  padding: 1rem;
}

.social-buttons .btn {
  margin: 0 0.5rem 1rem;
}

.signup-section {
  padding: 0.3rem 0rem;
}

5. Now, load the jQuery JavaScript library, Popper, and Bootstrap JS just before the closing of the body tag.

<!-- jQuery -->
<script src='https://code.jquery.com/jquery-3.3.1.slim.min.js'></script>
<!-- Popper JS -->
<script src='https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js'></script>
<!-- Bootstrap JS -->
<script src='https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js'></script>

6. Finally, initialize the Bootstrap modal in the jQuery document ready function.

$(document).ready(function() {             
$('#loginModal').modal('show');
  $(function () {
    $('[data-toggle="tooltip"]').tooltip()
  })
});
