纯粹的CSS问题，滑动动画的变化幻灯片

Question

我已经创建了基于CSS的Carousal。我用javascript只是为了自动改变幻灯片，其他都是CSS。我试图通过CSS"过渡"属性来改变每张幻灯片的滑动动画效果，但它不会在整个幻灯片容器中滑动。HTML:

<div class="carousel">
    <div class="carousel-inner" id="carousel-inner">
        <input class="carousel-open" type="radio" id="carousel-1" name="carousel" aria-hidden="true" hidden="" checked="checked">
        <div class="carousel-item">
            <h1>This is my first slide</h1>
        </div>
        <input class="carousel-open" type="radio" id="carousel-2" name="carousel" aria-hidden="true" hidden="">
        <div class="carousel-item">
            <h1>This is my second slide</h1>
        </div>
        <input class="carousel-open" type="radio" id="carousel-3" name="carousel" aria-hidden="true" hidden="">
        <div class="carousel-item">
            <h1>This is my third slide</h1>
        </div>
        <label for="carousel-3" class="carousel-control prev control-1">‹</label>
        <label for="carousel-2" class="carousel-control next control-1">›</label>
        <label for="carousel-1" class="carousel-control prev control-2">‹</label>
        <label for="carousel-3" class="carousel-control next control-2">›</label>
        <label for="carousel-2" class="carousel-control prev control-3">‹</label>
        <label for="carousel-1" class="carousel-control next control-3">›</label>
        <ol class="carousel-indicators">
            <li>
                <label for="carousel-1" class="carousel-bullet">&#9679;</label>
            </li>
            <li>
                <label for="carousel-2" class="carousel-bullet">&#9679;</label>
            </li>
            <li>
                <label for="carousel-3" class="carousel-bullet">&#9679;</label>
            </li>
        </ol>
    </div>
</div>

Javascript:

var n = 0;
window.ev = false;
document.getElementById("carousel-inner").onmouseenter = function () {
    window.ev = true;
};
document.getElementById("carousel-inner").onmouseleave = function () {
    window.ev = false;
    setTimeout(autoSlide, 400);
};
function autoSlide() {
    if (window.ev == false) {
        n++;
        if (n === 4)
            n = 1;
        document.getElementById("carousel-" + n).checked = true;
        setTimeout(autoSlide, 4000);
    }
}
autoSlide();

CSS:

.carousel {
    position: relative;
    box-shadow: 0 1px 6px rgba(0, 0, 0, 0.64);
    width: 100%;
}
.carousel-inner {
    position: relative;
    overflow: hidden;
    width: 100%;
}
.carousel-open:checked + .carousel-item {
    position: static;
    opacity: 100;
}
.carousel-item {
    position: absolute;
    opacity: 0;
    -webkit-transition: opacity 0.6s ease-out;
    transition: opacity 0.6s ease-out;
    display: block;
    min-height: 330px;
    width: calc(100% - 100px);
    margin: 0 auto;
}
.carousel-control {
    border-radius: 50%;
    color: #aaa;
    cursor: pointer;
    display: none;
    font-size: 80px;
    line-height: 35px;
    position: absolute;
    top: 50%;
    -webkit-transform: translate(0, -50%);
    cursor: pointer;
    -ms-transform: translate(0, -50%);
    transform: translate(0, -50%);
    text-align: center;
    width: 40px;
    z-index: 10;
}
.carousel-control.prev {
    left: 2%;
}
.carousel-control.next {
    right: 2%;
}
.carousel-control:hover {
    color: #000;
}
#carousel-1:checked ~ .control-1,
#carousel-2:checked ~ .control-2,
#carousel-3:checked ~ .control-3 {
    display: block;
}
.carousel-indicators {
    list-style: none;
    margin: 0;
    padding: 0;
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
    text-align: center;
    z-index: 10;
}
.carousel-indicators li {
    display: inline-block;
}
.carousel-bullet {
    color: #757575;
    cursor: pointer;
    display: block;
    font-size: 24px;
    font-weight: 300;
}
#carousel-1:checked ~ .control-1 ~ .carousel-indicators li:nth-child(1) .carousel-bullet,
#carousel-2:checked ~ .control-2 ~ .carousel-indicators li:nth-child(2) .carousel-bullet,
#carousel-3:checked ~ .control-3 ~ .carousel-indicators li:nth-child(3) .carousel-bullet {
    color: #009eb1;
}
 .carousel-item {
    background: lightblue;
    padding: 20px;
    text-align: center;
}

很酷的想法，顺便说一句，在CSS中制作沉重/连续的动画总是很好的GPU杠杆。

CSS中的小问题:-)

您只在控件上使用了transform属性，这是多余的。

你需要:

1)添加过渡到所有，而不仅仅是项目的不透明度。2)让选中的项目的平移量为0，让未选中的项目的x轴平移量为100%(你可以设置为负值来切换方向)

这是我从你那里分叉的jsfiddle: jsfiddle

下面是更新后的代码片段:

var n = 0;
window.ev = false;
document.getElementById("carousel-inner").onmouseenter = function () {
    window.ev = true;
};
document.getElementById("carousel-inner").onmouseleave = function () {
    window.ev = false;
    setTimeout(autoSlide, 400);
};
function autoSlide() {
    if (window.ev == false) {
        n++;
        if (n === 4)
            n = 1;
        document.getElementById("carousel-" + n).checked = true;
        setTimeout(autoSlide, 4000);
    }
}
autoSlide();
