Tips for creating a gradual fade-out effect on a bootstrap modal window

One issue I'm facing is with my modal dialog (#busyIndicator). It simply displays a message that reads "Please Wait". Sometimes, the operation it's tied to completes so quickly that the visual transition between showing and hiding the dialog becomes a rapid blur. This can be quite disorienting and uncomfortable for users.

I'm wondering if there's a way to make the modal disappear more gradually, maybe by introducing a delay when it fades out. I attempted to achieve this effect using

$('#busyIndicator').fadeOut(2000).modal('hide');

, but unfortunately, it doesn't seem to have the desired impact.

Enter the desired closing duration and modal selector.

var timer,
    closingTime = 3000,
    modal = $('#myModal');

modal
    .on('hide.bs.modal', function (e) {
        if (timer) {
            timer = false;
        } else {
            e.preventDefault();
            timer = true;
            modal.animate({
                opacity: 0
            }, closingTime - 150, function () {
                modal.modal("hide");
            })
        }
    })
    .on('hidden.bs.modal', function () {
        modal.css({
            opacity: 1
        })
    })

.center-me {
   min-height: 50vh;
   display: flex;
   align-items: center;
   justify-content: center;
}

It's common practice to execute your JavaScript code within a callback function of $.fadeOut(). This way, the JS code inside the callback will only run after the completion of the $.fadeOut() method.

$('#busyIndicator').fadeOut(2000,function() {
  $(this).modal('hide');
});

Default Bootstrap modals come with a fade effect, as it is part of their predefined CSS transitions. However, if you wish to modify the speed of the fading effect, follow these steps:

.fade {
    opacity: 0;
    -webkit-transition: opacity 1s linear;
    transition: opacity 1s linear;
}

Initially, this setting will make the fading process extremely slow. To adjust the speed, simply change the transition time value from 1s to a smaller number such as 0.3s.
