我在页面中添加了一些CSS后，我开始遇到一些问题。默认情况下，水平线在中心对齐，默认情况下，我的线条在左侧对齐。此外，列表的数字和项目符号没有出现。这是代码： 首先，这是我正在使用的CSS菜单的代码：

min-height:100%;
/* The Magic */
background-size:cover;
}
body{
/* Workaround for some mobile browsers */
min-height:100%;
}
a, a:visited {
outline:none;
color:#1c4f64;
}
a:hover{
text-decoration:none;
}
section, footer, header{
display: block;
}
/*----------------------------

我应该解决什么问题所以我不会遇到这些问题？
答案 0 :(得分：0)
在你的CSS中
.menu, .menu ul {
list-style:none;
我们需要查看您的HTML，但我怀疑这是继承的，因此您的编号列表和项目符号无效。
