圖中紅色筆劃著的地方應(yīng)該怎么解讀？為什么我原來(lái)用?????? li.ect:hover li.hide{display:block;}??代替紅色筆的地方時(shí)功能不能正確運(yùn)行？完整代碼如下：<!DOCTYPE?html>
<html>
<head>
<meta?charset="UTF-8">
<title>列表</title>
<style>
????????ul{list-style:?url(

);}
????????*{margin:0px;}
????????div{border:1px?solid?;width:100px;margin:50px;}
????????li.hide{display:none;}
????????li.ect:hover?li.hide{display:block;}
</style>
