Question

我希望我的导航栏是navbar-fixed-top。渐变条应位于导航栏的顶部，就像附加的图像一样。我尝试过这段代码，但是navbar-fixed-top类隐藏了它下面的渐变条，渐变条不再可见。我想要一个纯粹的Css解决方案，没有任何jQuery或javascript。

body{ background: grey!important;
}
/*+++++++ COLOR BAR ++++++++*/
.color-bar{ width: 100%;
    	    height: 4px;	
            background: -webkit-linear-gradient(left, #f0c24b 0%, #b5d56a 20%, #ea7066 40%, #84bed6 60%, #a597e7 80%, #ea77ad 100%);
            background: -o-linear-gradient(left, #f0c24b 0%, #b5d56a 20%, #ea7066 40%, #84bed6 60%, #a597e7 80%, #ea77ad 100%);
            background: linear-gradient(to right, #f0c24b 0%, #b5d56a 20%, #ea7066 40%, #84bed6 60%, #a597e7 80%, #ea77ad 100%);

Answer 1

查看CSS的z-index feature。通过使用z-index，您可以通过向前拉一些或向后推一些来优先处理源中的不同层。

如果将CSS行z-index: 10;添加到.color-bar类，它应该在z-index低于10（默认为0）的任何内容之前将其拉出。

在navbar-fixed-top上添加渐变条。在滚动时，应隐藏渐变条
