我正在尝试使用attr
创建一个检查html图标文件的列表li .school-list {
position: relative;
display:block;
}
.school-list::before {
content: attr(icon string,"hello");
display:block;
background-repeat: no-repeat;
background-size: cover;
width: 10px;
height:10px;
position: absolute;
top: 50%;
transform: translateY(-50%);
}
目前我只是想在内容中显示值,但如果我使用“string”作为值类型,它会100%失败。我究竟做错了什么?
这是我现在正在使用的HTML
