css - 如何将两个 CSS 渐变背景放在一个 div 中？

Question

我有以下 CSS:

.main {
    padding-right: 15px;
    padding-left: 15px;
    /* IE9 SVG, needs conditional override of 'filter' to 'none' */
    background: url(data:image/svg+xml;base64,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)top;

    background-size: Auto 200px;
    background-repeat: repeat-x;
    padding-top: 50px;
    min-height:600px;
}

这是一个实例:http://jsfiddle.net/ZtJmM/

我希望一个渐变位于元素的顶部，一个渐变位于元素的底部。那可能吗？

谢谢!

是的，在同一个语句中使用它们，例如:

background: linear-gradient(to bottom, rgba(229,229,229,1) 0%,
                                       rgba(255,255,255,0) 100%) top, 
            linear-gradient(to bottom, rgba(229,229,229,1) 0%,
                                       rgba(255,255,255,0) 100%) bottom;
