Bootstrap 4 多项目轮播（单击循环所有新项目）[重复]答案

【问题标题】：Bootstrap 4 Multiple Item Carousel (Click cycles all new items) [duplicate]Bootstrap 4 多项目轮播（单击循环所有新项目）[重复]
【发布时间】：2018-09-19 05:27:13
【问题描述】：

尝试使用引导 4 轮播功能来执行此操作（下图是 bootstrap 3 variant）

我尝试将其转换为引导程序 4。我对它所做的是通过 html 上的 bootstrap 3 → to bootstrap 4 html conversion tool 运行它，并调整对 CDN 中引导程序 JS 和 CSS 文件的引用。我还用颜色更改了图像引用，以便更容易区分我想要显示的图像。

下面是代码，它没有在一张幻灯片上显示所有 4 张图片

$(document).ready(function() {
    $('#Carousel').carousel({
        interval: 5000
    })
});

body{padding-top:20px;}
.carousel {
    margin-bottom: 0;
    padding: 0 40px 30px 40px;
}
/* The controlsy */
.carousel-control {
	left: -12px;
    height: 40px;
	width: 40px;
    background: none repeat scroll 0 0 #222222;
    border: 4px solid #FFFFFF;
    border-radius: 23px 23px 23px 23px;
    margin-top: 90px;
}
.carousel-control.right {
	right: -12px;
}
/* The indicators */
.carousel-indicators {
	right: 50%;
	top: auto;
	bottom: -10px;
	margin-right: -19px;
}
/* The colour of the indicators */
.carousel-indicators li {
	background: #cecece;
}
.carousel-indicators .active {
background: #428bca;
}

@Zimsystem 你真的看过类似的stackoverflow帖子吗？它们在功能上不一样。该问题对源代码有参考。我已经在互联网上搜索了几个小时的解决方案，这是我唯一知道的。如果您不将其保留为副本，我将不胜感激，因为这样做会损害 stackoverflow。
编辑问题以显示您到目前为止所尝试的内容。代码应该在问题中。然后解释它为什么不与同一主题的许多其他问题重复。

使用 4 项检查此引导 v4 轮播：

【讨论】：

你能把按钮也放在左边/右边吗:)。
箭头也添加到左侧/右侧。
滑动时图片也会弹出一点，有没有办法不让？
只需通过添加.class 删除.container 的左右填充或查看更新的答案。
这可能“有效”达到预期目的，但它没有正确使用 Bootstrap 4。

【解决方案2】：

这是你想要的吗？
