我想做一条如下所示的垂直线：

我试过以下代码：

div.vertical-line{
    float:right;
    width:5px;
    background-color:black;
    margin-right:20px;
    background: #FFFFFF;
    background: -webkit-gradient(linear, 0 0, 0 bottom, from(#FFFFFF), to(#CFCFCF));
    background: -webkit-linear-gradient(#FFFFFF, #CFCFCF);
    background: -moz-linear-gradient(#FFFFFF, #CFCFCF);
    background: -ms-linear-gradient(#FFFFFF, #CFCFCF);
    background: -o-linear-gradient(#FFFFFF, #CFCFCF);
    background: linear-gradient(#FFFFFF, #CFCFCF);
    -pie-background: linear-gradient(#FFFFFF, #CFCFCF);
    behavior: url(/pie/PIE.htc);
}

但结果并不如预期。这是结果：http: //jsfiddle.net/rLyyc/

它很接近，但它不会在行尾“淡出”。

有什么建议么？

提前致谢！

您需要添加另一个停止点，即

background: -webkit-gradient(linear, 0 0, 0 bottom, from(#FFFFFF), to(#CFCFCF), to(#FFFFFF));

导致：

div.vertical-line{
    float:right;
    width:5px;
    background-color:black;
    margin-right:20px;
    min-height: 550px;
    height:100%;
    background: #FFFFFF;
    background: -webkit-gradient(linear, 0 0, 0 bottom, from(#FFFFFF), to(#CFCFCF), to(#FFFFFF));
    background: -webkit-linear-gradient(#FFFFFF, #CFCFCF, #FFFFFF);
    background: -moz-linear-gradient(#FFFFFF, #CFCFCF, #FFFFFF);
    background: -ms-linear-gradient(#FFFFFF, #CFCFCF, #FFFFFF);
    background: -o-linear-gradient(#FFFFFF, #CFCFCF, #FFFFFF);
    background: linear-gradient(#FFFFFF, #CFCFCF, #FFFFFF);
    -pie-background: linear-gradient(#FFFFFF, #CFCFCF, #FFFFFF);
    behavior: url(/pie/PIE.htc);
}

值得查看 MDN 以了解颜色停止在线性渐变中的工作原理：https ://developer.mozilla.org/en-US/docs/Web/CSS/linear-gradient

使用这个生成器，我为你得到了这个：

background: #ffffff; /* Old browsers */
background: -moz-linear-gradient(top,  #ffffff 0%, #c6cbd2 50%, #ffffff 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ffffff), color-stop(50%,#c6cbd2), color-stop(100%,#ffffff)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top,  #ffffff 0%,#c6cbd2 50%,#ffffff 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top,  #ffffff 0%,#c6cbd2 50%,#ffffff 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top,  #ffffff 0%,#c6cbd2 50%,#ffffff 100%); /* IE10+ */
background: linear-gradient(to bottom,  #ffffff 0%,#c6cbd2 50%,#ffffff 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#ffffff',GradientType=0 ); /* IE6-9 */

这将创建您要查找的行并将其放置在页面中间。只需调整线条粗细的宽度，从上到下的线条高度的高度，在线条开始之前向下调整多远的高度，并将颜色调整为您想要的任何颜色。

body:after { 
    content:"";
    position: absolute;
    z-index: 1;
    top:50%;
    bottom:0;
    left:50%;
    border: 0;
    height: 80%;
    width:1px;
    background: #333;
    background-image: 
        -webkit-linear-gradient(top, #ccc, #333, #ccc);
        background-image: -moz-linear-gradient(top, #ccc, #333, #ccc);
        background-image: -ms-linear-gradient(top, #ccc, #333, #ccc);
        background-image: -o-linear-gradient(top, #ccc, #333, #ccc);
    }
