How to make use of it:

1. Add options to the password generator.

<form class="formulario">
  <div class="alert alert-warning" id="alert-no-option" role="alert">
    Select at least one option!
  </div>
  <div class="col-sm">
    <div class="mb-3 form-check">
      <input type="checkbox" class="form-check-input" id="numbers">
      <label class="form-check-label" for="numbers">Numbers [0-9]</label>
    </div>
  </div>
  <div class="col-sm">
    <div class="mb-3 form-check">
      <input type="checkbox" class="form-check-input" id="lowercase">
      <label class="form-check-label" for="lowercase">Lowercase letters [a-z]</label>
    </div>
  </div>
  <div class="col-sm">
    <div class="mb-3 form-check">
      <input type="checkbox" class="form-check-input" id="uppercase">
      <label class="form-check-label" for="uppercase">Uppercase letters [A-Z]</label>
    </div>
  </div>
  <div class="col-sm">
    <div class="mb-3 form-check">
      <input type="checkbox" class="form-check-input" id="special">
      <label class="form-check-label" for="special">Special characters [!@#$%^&*()?]</label>
    </div>
  </div>
  <div class="col-sm">
    <div class="form-floating mb-3" id="quantity-form">
      <input type="number" min="8" class="form-control" id="quantity" value=8 required>
      <label for="quantity">Characters quantity</label>
    </div>
  </div>
  <button type="submit" id="send-button" class="btn btn-primary">Generate</button>
</form>

2. Create an input field to hold the generated password.

<input class="form-control" id="password" type="text" readonly>
<br>
<div class=" text-center alert alert-success" id="copied-alert" role="alert">
  Copied!
</div>

3. Hide the ‘No Option’ and ‘Password Copied’ messages on the web page.

#alert-no-option{
  display: none;
}

#copied-alert{
  display: none;
  margin: 0 auto;
  width: 300px;
  font-size: 20px;
}

4. Load the password generator script after the jQuery library.

<script src="/path/to/cdn/jquery.slim.min.js"></script>
<script src="/path/to/js/scripts.js"></script>
