自举垂直旋转木马
开箱即用，Bootstrap仅配有传统的水平旋转木马。此笔具有HTML和CSS，可以使用上/下旋转控制垂直设置动画
$('#carousel-example-vertical').on('slid', '', function() {
var $this = $(this);
if($('.carousel-inner .item:first').hasClass('active')) {
$('.up.carousel-control').hide();
} else if($('.carousel-inner .item:last').hasClass('active')) {
$('.down.carousel-control').hide();
} else {
$this.children('.carousel-control').show();
}
});
