Answer 1

从您粘贴的代码中，我看不到您正在加载引导库(css 和 js 代码(。您可以在此处查看引导加载信息 http://getbootstrap.com/getting-started/

Answer 2

轮播组件的完整描述在 boostrap 4 中报告。

相反，在此页面中，您将找到所需的库。

工作代码：

$(document).ready(function () {
    $('#Carousel').carousel({
        interval: 8000
    })
});

.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;
}
.carousel-indicators {
    right: 50%;
    top: auto;
    bottom: -10px;
    margin-right: -19px;
}
.carousel-indicators li {
    background: #cecece;
}
.carousel-indicators .active {
    background: #428bca;
}
