I have a simple jQuery modal. It works well, but I can’t set it horizontally middle. I’ve tried many approach, but it not centering anyway. It creates problem when I want to use "max-width: 400". It create problem and go on one side. I want to make it like bootstrap modal. Max-width: 400 and will be centered horizontally also. Please look at my code.
// common close button
$('.mi-modal-toggle').click(function() {
$(this).closest(".mi-modal").toggleClass('modal-visible');
});
// explicit button per modal
$('.mi-modal-toggle').on('click', function(e) {
var modalid = $(this).data("modal-id");
$(`.mi-modal[data-modal-id='${modalid}']`).toggleClass('modal-visible');

Instead of wrestling with margin and padding for centering, just use the standard left position and -50% x-axis translation.
