Good evening I have a little doubt, I'm opening a modal form and when I press the button that opens it, it comes out as if the modal form was inactive (I attached the image) and if I click on any part, it closes, maybe I'm forgetting a library? 'I leave the code with which I open the modal
<div>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#formModal">
<i class="fa fa-plus"></i>Agregar una cuenta
</button>
</div>
