Boostrap旋转木马左对齐

Question

我一直在编辑this code所以它是Bootstrap 4并且它左对齐。我无法弄清楚如何解决两件事：

1. 即使我希望它显示100％
，右侧仍会被切断
2. 当您点击箭头（carousel-control-prev）时，会出现在其他轮播项目滑动之前显示的空白区域

有人可以让我知道我做错了什么吗？这是我的代码：

＆＃13;
＆＃13;
$(document).ready(function() {
  $('#carouselExampleControls').carousel({
    interval: 0
  })
  $('.carousel .carousel-item').each(function() {
    var next = $(this).next();
    if (!next.length) {
      next = $(this).siblings(':first');
    }
    next.children(':first-child').clone().appendTo($(this));
    if (next.next().length > 0) {
      next.next().children(':first-child').clone().appendTo($(this));
    } else {
      $(this).siblings(':first').children(':first-child').clone().appendTo($(this));
    }
  });
});
＆＃13;
.carousel,
.carousel-inner,
.carousel-inner>.carousel-item {
  overflow: hidden;
}

.carousel-inner>.carousel-item.active,
.carousel-inner>.carousel-item-next {
  display: flex;
  flex-wrap: nowrap;
  width: auto;
}

.carousel-inner:before {
  position: absolute;
  top: 0;
  bottom: 0;
  right: 94%;
  left: 0;
  content: "";
  display: block;
  background-color: #fff;
  z-index: 2;
}

.carousel-inner:after {
  position: absolute;
  top: 0;
  bottom: 0;
  right: 0;
  left: 100%;
  content: "";
  display: block;
  background-color: #fff;
  z-index: 2;
}

.carousel-control-prev {
  opacity: 1;
  background: black;
  height: 70px;
  width: 70px;
  top: 50%;
  left: 100px;
}

Answer 1

Bootstrap基于12列网格。因此，如果您将三张幻灯片分组为一行，每张幻灯片的类别为col-4，则可以解决您的问题。我还在班级width:auto;中将width: 100%;更改为.carousel-inner > .carousel-item.active, .carousel-inner > .carousel-item-next。

<div class="container-fluid">
    <div class="row">
        <div class="col-12 text-center">
            <h3>Bootstap 4 Carousel</h3>
            <h6>Customized to advance a single slide, and reveal part of adjacent slides</h6>
