enter image description hereI have a close button on my alert but when I click on it it doesn’t close. I have seen similar people with the same problem but none of the solutions have worked for me

This is what I currently have

{% for message in messages %}
<div class="container-fluid p-0">
  <div class="alert {{ message.tags }} alert-dismissible fade show" role="alert">
    <button type="button" class="close" data-dismiss="alert" aria-label="Close">
      <span aria-hidden="true">×</span>
    </button>
    {{ message }}
  </div>
</div>
{% endfor %}
