能搭个顺风车吗？我在看牛津中阶双解【CSS】2019.12.12
的css
参照您的css，我把其中相关的类似部分找了出来：
/*
}
div.explain {
margin-left: 18px;
counter-reset: inum pvnum;
}
span.id:before {
content: counter(inum)“.”;
counter-increment: inum;
}
span.phr:before{
content: counter(pvnum)“.”;
counter-increment: pvnum;
}
/
对相关对应标签很迷惑，只能找到
/
.num {
color:#ff7723;
font-weight: bold;
display: block;
float: left;
margin-top: 1px;
margin-left: -18px;
text-align: right;
width: 10px;
position: absolute;
*/
没弄懂，能否麻烦您给注释解析下。Thank you in advance！！！
