一个div中有两个图像，中间有滑块。

Question

我试图在一个div上显示两个图像。它们最初将被一个有两个箭头的手柄线分开。当用户向左拖动句柄线时，左侧图像将捕获与用户拖动相关的更多空间。右边的图像也是一样的。我跟随这个网站图片的例子->网站：http://california-t.ferrari.com/en/#overview

<div class="content">
    <div class="sketch">
    </div>
      <div class="sketch-wrapper">
                                    <div class="before-after sketch-container" style="height: 270px;">
                                        <img class="sketch-before" alt="sketch basis" src="Untitled.jpg" style="clip: rect(0px, 380px, 270px, 0px;"></img>
                                        <img class="sketch-after" alt="sketch finished" src="sketch2T.jpg" style=";"></img>
                                      <div class="sketch-overlay">
                                            <div class="sketch-before-label"></div>
                                            <div class="sketch-after-label"></div>
                                      </div>
                                        <div class="sketch-handle" style="left: 380px;">
                                            <span class="sketch-left-arrow"></span>
                                            <span class="sketch-right-arrow"></span>
                                        </div> 
                                    </div>
                                </div>


   </div>

下面是CSS：

.content {

    width: 900px;

    position: relative;
    margin-left: auto;
    margin-top:0px;





}

.sketch{
    width:inherit;
    height: 1200px;
    background-image: url(backSketch4.jpg);
    margin-top: 70px;

}

.sketch-wrapper{
    height: 270;
    width: 760px;
    display:block;
    margin-top: -1025px;
    margin-left:70px;

}
.sketch-container{
    display:block;
    -mox-box-sizing: content-box;
    -ms-box-sizing: content-box;
    -o-box-sizing: content-box;
    -webkit-box-sizing: content-box;
    overflow: hidden;
    position: relative;
    -moz-user-select: none;
    -webkit-user-select:none;
}
.sketch-before, .sketch-after {
    margin-top: 0px;
    width: 100%;
    position: absolute;
    top: 0px;
    display: block;
    border: 0px;
    margin: 0px 0px 0px;    
}
.sketch-before{
    z-index: 20;
}
.sketch-after{
    z-index: 10;    
}

.sketch-overlay, .sketch-before-label, .sketch-after-label {
    transition-duration: 0.5s;
    -webkit-transition-duration: 0.5s;
    -moz-transition-duration: 0.5s;
    -ms-transition-duration: 0.5s;
    -o-transition-duration: 0.5s;
}
.sketch-overlay, .sketch-before-label, .sketch-after-label {
    position: absolute;

    width: 100%;
    height: 100%;

}
.sketch-before-label, .sketch-after-label{
    transition-property: opacity;   
}
.sketch-before-label:before, .sketch-after-label:before {
    background: none repeat scroll 0% 0% rgba(255, 255, 255, 0.2);
    position: absolute;
    top: 50%;
    margin-top: -19%;
    line-height: 38px;
    padding: 0px 20px;
    border-radius: 2px;
}
.sketch-before-label:before, .sketch-after-label:before {
    color: #FFF;
    font-size: 12px;
    letter-spacing: 0.1em;  
}
.sketch-handle {
    height: 38px;
    width: 38px;
    position: absolute;

    top: 50%;
    margin-left: -22px;
    margin-top: -22px;
    border: 3px solid #0F0;
    border-radius: 1000px;
    -moz-border-radius: 1000px;

    -webkit-border-radius:1000px;
    box-shadow: 0px 0px 12px rgba(51, 51, 51, 0.5);
    -webkit-box-shadow: 0px 0px 12px rgba(51, 51, 51, 0.5);
    -moz-box-shadow: 0px 0px 12px rgba(51, 51, 51, 0.5);

    z-index: 40;    
}
.sketch-handle:after {
    top: 50%;
    margin-top: 22px;
    box-shadow: 0px -3px 0px #FFF, 0px 0px 12px rgba(51, 51, 51, 0.5);  
}
.sketch-handle:before {
    bottom: 50%;
    margin-bottom: 22px;
    box-shadow: 0px 3px 0px #FFF, 0px 0px 12px rgba(51, 51, 51, 0.5);
}
.sketch-handle:before, .sketch-handle:after {
    content: " ";
    display: block;
    width: 3px;
    background: none repeat scroll 0% 0% #FFF;

    height: 9999px;
    position: absolute;
    left: 50%;
    margin-left: -1.5px;
    z-index: 30;
    box-shadow: 0px 0px 12px rgba(51, 51, 51, 0.5);
    -moz-box-shadow: 0px 0px 12px rgba(51, 51, 51, 0.5);
}
.sketch-left-arrow {

    border-right: 6px solid #F00;
    left: 50%;
    margin-left: -17px;
    box-sizing:content-box; 
    -moz-box-sizing: content-box;
}
.sketch-right-arrow {
    border-left: 6px solid #F00;
    right: 50%;
    margin-right: -17px;
    box-sizing:content-box; 
    -moz-box-sizing: content-box;
}
.sketch-left-arrow, .sketch-right-arrow {
    width: 0px;
    height: 0px;
    border: 6px inset transparent;
    position: absolute;
    top: 50%;
    margin-top: -6px;   
}

到目前为止，我的结果是，滑块没有移动，第二个图像从中心到右边不可见.我认为css有问题.http://imageshack.com/a/img855/517/i7wf.jpg

这是我的尝试。

它可能需要一些微调。
