Rendering:

Isn’t the image switching very personalized? , the effect is also very good, you can use it on your own website.

Look at the html first:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
        "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <title></title>
    <meta content="text/html;charset=utf-8" http-equiv="content-type">
    <link type="text/css" href="reset.css" rel="stylesheet">
    <link type="text/css" href="main.css" rel="stylesheet">

    <script type="text/javascript" src="../../jquery-1.8.3.js"></script>
    <script type="text/javascript" src="vcd.js"></script>

    <script type="text/javascript">

        $(function ()
        {
            vcd.init();
            vcd.autoPlay();
        });

    </script>

</head>
<body>

<p id="vcd">

    <i id="cd"></i>
    <ul>
        <li class="active"><a><img alt="超人归来" src="ad/1.jpg"/></a></li>
        <li><a><img alt="超凡蜘蛛侠" src="ad/2.jpg"/></a></li>
        <li><a><img alt="黑暗骑士：蝙蝠侠" src="ad/3.jpg"/></a></li>
        <li><a><img alt="美国队长" src="ad/4.jpg"/></a></li>
        <li><a><img alt="雷神托儿" src="ad/5.jpg"/></a></li>
        <li><a><img alt="金刚狼" src="ad/6.jpg"/></a></li>
    </ul>
    <a id="wrapPager" title="超人归来" target="_blank"></a>

    <p id="indexBar">
        <a class="active">0</a>
        <a href="#">1</a>
        <a href="#">2</a>
        <a href="#">3</a>
        <a href="#">4</a>
        <a href="#">5</a>
    </p>

</p>


</body>
</html>

You can see that p#vcd is the outermost container, and a background is set for it; ul li sets the picture elements separately; i#cd Set the background to the CD, and then set the display position; display the index of the picture in p#indexBar for clicks.

CSS:

#vcd, #vcd ul, #vcd #wrapPager
{
    width: 200px;
    height: 272px;
}

#vcd, #vcd ul, #vcd #wrapPager, #cd
{
    background: url("images/disk.png") no-repeat 0 0;
}

#vcd
{
    position: relative;
    margin: 20px auto 0;
}

#vcd ul, #vcd #wrapPager, #cd
{
    position: absolute;
}

#vcd ul
{
    background-position: -263px 3px;
}

#vcd ul li, #vcd ul li a, #vcd ul li a img
{
    display: block;
    width: 178px;
    height: 264px;
    overflow: hidden;
}

#vcd ul li
{
    top: 5px;
    left: 2px;
    opacity: 0;
    /*visibility: hidden;*/
    -webkit-transition: opacity  linear .6s;
    /*-webkit-transition: visibility  linear .6s;*/
    -moz-transition: opacity  linear .6s;
    -ms-transition: opacity  linear .6s;
    transition: opacity  linear .6s;
    position: absolute;
}

#vcd ul li.active
{
    opacity: 1;
    /*visibility: visible;*/
}

#vcd #cd
{
    top: 64px;
    left: 78px;
    width: 146px;
    height: 146px;
    background-position: -510px 0;
    -webkit-transition: left ease .4s, -webkit-transform ease 1.2s .44s;
    -moz-transition: left ease .4s, -moz-transform ease 1.2s .44s;
    -ms-transition: left ease .4s, -ms-transform ease 1.2s .44s;
    transition: left ease .4s, transform ease 1.2s .44s;
}

#vcd #cd.switch
{
    left: 120px;
    -webkit-transform: rotate(2520deg);
    -moz-transform: rotate(2520deg);
    -ms-transform: rotate(2520deg);
    transform: rotate(2520deg);
}

#vcd #wrapPager
{
    display: block;
    left: 0;
    top: 2px;
}

#vcd #indexBar
{
    top: 235px;
    left: 25px;
    text-align: center;
    overflow: hidden;
    opacity: 0;
    visibility: hidden;
    -webkit-transition: opacity linear .6s;
    -moz-transition: opacity linear .6s;
    -ms-transition: opacity linear .6s;
    transition: opacity linear .6s;
    position: absolute;
}

#vcd:hover #indexBar
{
    opacity: 1;
    visibility: visible;
}

#vcd #indexBar a
{
    display: inline-block;
    margin: 0 4px;
    height: 0;
    width: 0;
    border: 4px #9f9f9f solid;
    border-radius: 100%;
    text-indent: -200px;
    overflow: hidden;
}

#vcd #indexBar a:hover, #vcd #indexBar a.active
{
    width: 4px;
    height: 4px;
    border-color: #05c7fe;
    border-width: 2px;
}

You can follow the CSS, the layout of the position is mainly It just relies on position:relative and position:absolute; and then you will find the transition and transformation using CSS3: transition and transform. Let me briefly mention:

1, transition: left 1s ease 0s;

Parameter 1: The attribute that requires transition effect can be a single attribute: width, left, etc., or it can be set to all.

Parameter 2: The duration of the transition

Parameter 3: The speed animation of the transition. If you are interested, you can check this. It is slow first and then fast, uniform speed and so on.

Parameter 4: Delay time for transition start

Transition also supports the following writing:

transition-property: border, color, text-shadow;

transition-duration:2s, 3s, 3s;

2. Transform supports several deformations

transform:scale(0.5) scaling

transform:rotate(90deg)rotation 90 degrees

transform:skew(10deg 2deg) obliquely cut, the rectangle is converted into a parallelogram

transform:matrix() This matrix is transformed http://www.php .cn/ This website provides an online design matrix

transform:translate(40px 20px) translation

Exception provides: transform-origin: 20% 20%; used to modify the transformation effect The starting point defaults to the key

Of course, our example uses rotation, so there is no need to modify the starting point of the deformation effect.

Finally, JS:

var vcd = {
        /**
         * 常量
         */
        ID_VCD: "vcd",
        ID_INDEXBAR: "indexBar",
        ID_CD: "cd",
        CLASS_ACTIVE: "active",
        CLASS_CD_SWITCH: "switch",
        currentIndex: 0,
        isRunning: false,
        timer: null,
        init: function ()
        {
            /**
             * 初始化数据与事件
             */
            vcd.vcd = $("#" + vcd.ID_VCD);
            vcd.cd = $("#" + vcd.ID_CD);
            vcd.imgs = $("li", vcd.vcd);
            vcd.indexBar = $("#" + vcd.ID_INDEXBAR);

            vcd.vcd.mouseover(function (event)
            {
                clearInterval(vcd.timer);
            });
            vcd.vcd.mouseout(function ()
            {
                vcd.autoPlay();
            })
            ;
            $("a", vcd.indexBar).click(vcd.dotClick);

        },
        /**
         * 按钮点击切换
         * @param event
         */
        dotClick: function (event)
        {
            //如果当前动画还在运行，则直接返回
            if (vcd.isRunning)return;
            vcd.isRunning = true;
            $("a", vcd.indexBar).removeClass(vcd.CLASS_ACTIVE);
            $(this).addClass(vcd.CLASS_ACTIVE);
            vcd.currentIndex = $(this).text();
            vcd.cd.addClass(vcd.CLASS_CD_SWITCH);
            setTimeout(vcd.resetDotClick, 1500);
            event.preventDefault();//阻止a的默认跳转页面

        },
        /**
         * 当cd动画结束后，更新图片
         */
        resetDotClick: function ()
        {
            vcd.cd.removeClass(vcd.CLASS_CD_SWITCH);
            vcd.imgs.removeClass(vcd.CLASS_ACTIVE);
            vcd.imgs.eq(vcd.currentIndex).addClass(vcd.CLASS_ACTIVE);
            vcd.isRunning = false;
        },
        autoClick: function ()
        {
            var as = $("a", vcd.indexBar);
            vcd.currentIndex++;
            if (vcd.currentIndex == as.length)
            {
                vcd.currentIndex = 0;
            }
            as.removeClass(vcd.CLASS_ACTIVE);
            as.eq(vcd.currentIndex).addClass(vcd.CLASS_ACTIVE);
            vcd.cd.addClass(vcd.CLASS_CD_SWITCH);
            setTimeout(vcd.resetDotClick, 1500);
        },
        /**
         * 自动播放
         */
        autoPlay: function ()
        {
            vcd.timer = setInterval(function ()
            {
                vcd.autoClick();
            }, 3000);
        }

    }
    ;

The way to write a singleton is to define an object, and then the user Called through vcd.init(); vsd.autoPlay(),

    <script type="text/javascript">

        $(function ()
        {
            vcd.init();
            vcd.autoPlay();
        });

    </script>
