如何在圆盘传送带滑块中的图像之间添加间隙或如何在滑动时消除毛刺

我参考此link制作了一个轮播,并最初发布在此link上,但是不幸的是,我不希望在第一张图像中填充任何内容。所以我删除了第一张图片的填充,但创建了很大的图片宽度。

所以我删除了所有图像的填充,并为空白添加了margin-left

.carousel-item img {
    padding: 0;
    margin-right: 1rem; /* for gap */
}

但是当我滑动它时会产生某种类型的故障。

因此任何在图像之间添加间隙的解决方案(不在第一张和最后一张图像中)

$('#travelCarousel').carousel({
    interval: false
});

$('#travelCarousel.carousel .carousel-item').each(function(){
    let next = $(this).next();
    if (!next.length) {
        next = $(this).siblings(':first');
    }
    next.children(':first-child').clone().appendTo($(this));

    for (let i=0;i<3;i++) {
        next=next.next();
        if (!next.length) {
            next = $(this).siblings(':first');
        }

        next.children(':first-child').clone().appendTo($(this));
    }
});

不要使用像SLICK.JS这样的任何第三方JS

谢谢!

我认为,这种方法最大的问题是硬编码的“ 33.333%”过渡没有考虑缺口/余量。如果您将calc(x% + gap)用作过渡的值,则效果很好。

此外,要适应所有更改可见幻灯片数量的引导程序断点,您需要添加不同的过渡偏移量(例如,小屏幕偏移量为20%,大屏幕偏移量为50%)。可以在下面的codepen中找到这种方法的大致示例。

此故障是由于以下事实造成的:间隙是透明的,并且您可以通过它们看到下一个/上一个滑动项。一种想法是使这些间隙不透明。

例如,您可以在图像中添加白色box-shadow以覆盖透明间隙:

.carousel-item img {
    padding: 0;
    margin-right: 1rem;
    /*added this*/
    box-shadow: 
       1rem 0 #fff,
      -1rem 0 0 #fff; 
}

$('#travelCarousel').carousel({
    interval: false
});

$('#travelCarousel.carousel .carousel-item').each(function(){
    let next = $(this).next();
    if (!next.length) {
        next = $(this).siblings(':first');
    }
    next.children(':first-child').clone().appendTo($(this));

    for (let i=0;i<3;i++) {
        next=next.next();
        if (!next.length) {
            next = $(this).siblings(':first');
        }

        next.children(':first-child').clone().appendTo($(this));
    }
});
