inserir a descrição da imagem aquiI have two modal bootstrap , the first one a modal-Xl, the second one a modal-Sm that is smaller , they normally open. But the first of the effect of fade straight, already when I open the second the lower modal that is larger does not give the effect fade.

With this, the user may get confused, because the two modals are with equal visibility. I need that when opening the second modal, the first is faded.

My dear, you may be solving your problem this way, in bootstrap, by including two functions that make the modification in modal css, in different events:

 function esconderModalFundo(){
      $('#exampleModal').css('z-index', '0');
    }

    function mostrarModalFundo(){
      $('#exampleModal').css('z-index', '1050');
    }

    So that the z-index of the first modal fits when the user closes the second by clicking only outside it and not in the 'X' you can use the code below $('#exampleModal2'). on("Hidden.bs.modal", Function(e) { $('#exampleModal'). css('z-index', '1050'); })
