Custom log in form (branding -> Universal login -> Login) returns empty error and do not authorize user

Hello. I have trouble with custom login form. Here is src:

Sign In with Auth0 body, html { height: 100%; background-color: #f9f9f9; }
.login-container {
  position: relative;
  height: 100%;
}

.login-box {
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  padding: 15px;
  background-color: #fff;
  box-shadow: 0px 5px 5px #ccc;
  border-radius: 5px;
  border-top: 1px solid #e9e9e9;
}

.login-header {
  text-align: center;
}

.login-header img {
  width: 75px;
}

#error-message {
  display: none;
}

    <h5>LOG IN</h5>
  </div>
  <div id="error-message" class="alert alert-danger"></div>
  <form onsubmit="return false;" method="post">
    <div class="form-group">
     <label for="name">Username</label>
      <input
        type="text"
        class="form-control"
        id="email"
        placeholder="Enter your email">
    </div>
    <div class="form-group">
      <label for="name">Password</label>
      <input
        type="password"
        class="form-control"
        id="password"
        placeholder="Enter your password">
    </div>
    <div class="captcha-container form-group"></div>
    <button
      type="submit"
      id="btn-login"
      class="btn btn-primary btn-block">
        Log In
    </button>
  </form>
</div>
