问题

i already built the 2 sliders in different indexes ,, but when trying to make both of them in a single page their CSS and JQUERY will get mixed.........................

@media (min-width: 768px) {

/* show 3 items */
.carousel-inner .active,
.carousel-inner .active + .carousel-item,
.carousel-inner .active + .carousel-item + .carousel-item,
.carousel-inner .active + .carousel-item + .carousel-item + .carousel-item  {
    display: block;
}

.carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left),
.carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left) + .carousel-item,
.carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left) + .carousel-item + .carousel-item,
.carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left) + .carousel-item + .carousel-item + .carousel-item {
    transition: none;
}

.carousel-inner .carousel-item-next,
.carousel-inner .carousel-item-prev {
  position: relative;
  transform: translate3d(0, 0, 0);
}

.carousel-inner .active.carousel-item + .carousel-item + .carousel-item + .carousel-item + .carousel-item {
    position: absolute;
    top: 0;
    right: -25%;
    z-index: -1;
    display: block;
    visibility: visible;
}

/* left or forward direction */
.active.carousel-item-left + .carousel-item-next.carousel-item-left,
.carousel-item-next.carousel-item-left + .carousel-item,
.carousel-item-next.carousel-item-left + .carousel-item + .carousel-item,
.carousel-item-next.carousel-item-left + .carousel-item + .carousel-item + .carousel-item,
.carousel-item-next.carousel-item-left + .carousel-item + .carousel-item + .carousel-item + .carousel-item {
    position: relative;
    transform: translate3d(-100%, 0, 0);
    visibility: visible;
}

/* farthest right hidden item must be abso position for animations */
.carousel-inner .carousel-item-prev.carousel-item-right {
    position: absolute;
    top: 0;
    left: 0;
    z-index: -1;
    display: block;
    visibility: visible;
}

/* right or prev direction */
.active.carousel-item-right + .carousel-item-prev.carousel-item-right,
.carousel-item-prev.carousel-item-right + .carousel-item,
.carousel-item-prev.carousel-item-right + .carousel-item + .carousel-item,
.carousel-item-prev.carousel-item-right + .carousel-item + .carousel-item + .carousel-item,
.carousel-item-prev.carousel-item-right + .carousel-item + .carousel-item + .carousel-item + .carousel-item {
    position: relative;
    transform: translate3d(100%, 0, 0);
    visibility: visible;
    display: block;
    visibility: visible;
}

this is CSS of Second Slider

$('#carouselExample').on('slide.bs.carousel', function (e) {

var $e = $(e.relatedTarget);
var idx = $e.index();
var itemsPerSlide = 4;
var totalItems = $('.carousel-item').length;

if (idx >= totalItems-(itemsPerSlide-1)) {
    var it = itemsPerSlide - (totalItems - idx);
    for (var i=0; i<it; i++) {
        // append slides to end
        if (e.direction=="left") {
            $('.carousel-item').eq(i).appendTo('.carousel-inner');
        }
        else {
            $('.carousel-item').eq(0).appendTo('.carousel-inner');
        }
    }
}

});

this is JQuery of second slider

only if you tell me how to devide second slider jquery and css from first one its ok

Learn how jQuery class selectors work.

In this case you have 2 carousels, and therefore 2 elements with the class carousel on the same page. So, $('.carousel') can be used to select and handle the slide.bs.carousel event on both of the carousels.

To determine which carousel instance is being handled, use $(this). Read more about $(this). Then you can manipulate the CSS for that single carousel instance.

$('.carousel').on('slide.bs.carousel', function (e) {

    var $e = $(e.relatedTarget);
    var $t = $(this);
    var $inner = $t.find('.carousel-inner');
    var idx = $e.index();
    var itemsPerSlide = 3;
    var totalItems = $t.find('.carousel-item').length;

    if (idx >= totalItems-(itemsPerSlide-1)) {
        var it = itemsPerSlide - (totalItems - idx);
        for (var i=0; i<it; i++) {
            // append slides to end
            if (e.direction=="left") {
                $t.find('.carousel-item').eq(i).appendTo($inner);
            }
            else {
                $t.find('.carousel-item').eq(0).appendTo($inner);
            }
        }
    }
});

Please don't copy-and-paste this code without first understanding how it works!
