Question

我使用以下旋转木马滑块，我希望左右图像为黑色＆amp;白色除了居中的图像。我必须使用以下css3：-webkit-filter: grayscale(100%); filter: grayscale(100%);

我应该在哪里写呢？

<div class="container-fluid">    <!--  "container-fluid" -->
   <div class="row"> 
        <div class="col-md-12 center-block">
            <div class="carousel slide" id="myCarousel">
                <div class="carousel-inner">

Answer 1

尝试添加：

.item > div:first-child img,
.item > div:last-child img {
    -webkit-filter: grayscale(100%); filter: grayscale(100%);
}

测试结果：

$(document).ready(function () {
    $('#myCarousel').carousel({
        interval: 10000
    })
    $('.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));                  
        }
    });
