我试图在上面的列表中添加项目符号，但它们不会显示。
列表的图像我试图添加项目符号
这是我试图改变的css代码：
.arch ul {
list-style-type: circle;
margin-left: 1.5em;
list-style-position: inside;
}
这是我的完整代码供参考：

2 个答案:
答案 0 :(得分：1)
第一个问题是，您定位的.arch ul应该是ul.arch，同时还有一个list-style: none;规则应用于您的#first_half aside li，这样就无法显示要点。
答案 1 :(得分：0)
您需要更改
import certifi到
#first_half aside li
{ list-style: none;
padding: 0 0 7px 0; }
