我正在编辑一个客户的网站，有一件事让我头晕目眩。
我想在滚动后更改粘性菜单的颜色。有人可以通过自定义css帮助我进行这些更改吗？
这是我的css

您应该向我们提供一些代码，以便能够正确帮助..但简而言之
你需要一个滚动监听器（如果使用jquery）
.navbar-default .navbar-nav>.active>a,
.navbar-default .navbar-nav>.active>a:hover,
.navbar-default .navbar-nav>.active>a:focus {
background:none;
}
.navbar-default .navbar-nav.redColored{
background:#ff0000;
}
和CSS

这是一个粗略的例子，但希望你能得到这个概念。滚动后，您可以将标题添加到标题中。
对于该类的任何样式更改，如颜色在css中定义，但您需要一些简单的JS来检测您的滚动。请看这个例子（我根据高度的变化采取自己的自由）并根据您的需求进行定制
$(function() {
$(window).scroll(function() {
var scroll = $(window).scrollTop();
if (scroll >= 97) {
$("header").addClass('shrink');
} else {
$("header").removeClass("shrink");
}
});
});.container {
height: 900px;
overflow-y: scroll;
}
header {
background-color: blue;
width: 100%;
height: 100px;
position: fixed;
}
h1 {
font-size: 22px;
color: white;
}
header.shrink {
height: 50px;
background-color: red;
}
h1.shrink {
font-size: 14px;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body class="container">
<header><h1>I'm a header</h1></header>
</body>

只需在主题样式表的末尾添加：
def countpaths(row, column):
result = [[1] * column for r in range(row)]
for r in range(1, row):
for c in range(1, column):
result[r][c] = result[r][c-1] + result[r-1][c]
return result
paths = countpaths(3,7)
for r in paths:
print(r)
print(paths[0][0])
print(paths[2][6])
关于移动问题，您需要在css中搜索适当的媒体查询，并将上述内容添加到相应的块中。
