我在純 html 頁(yè)面中實(shí)現(xiàn)了可折疊，如下所示：<!DOCTYPE html><html><head> <title></title><style>button.accordion { background-color: #777; color: white; cursor: pointer; padding: 18px; width: 100%; border: none; text-align: left; outline: none; font-size: 15px;}button.accordion.active, button.accordion:hover { background-color: #555;}button.accordion:after { content: '\002B'; color: white; font-weight: bold; float: right; margin-left: 5px;}button.accordion.active:after { content: ''; background-image: url('download.jpg'); display: inline-block; background-size: 30px 30px; width:30px; height:30px; transform:rotate(180deg);}div.panel { padding: 0 18px; background-color: #f1f1f1; max-height: 0; overflow: hidden; transition: max-height 0.2s ease-out;}* { box-sizing: border-box;}#myUL { list-style-type: none; padding: 0; margin: 0;}a{ text-decoration: none; color:white;}</style></head><body><h2>Collapsible</h2><p>Click the button to toggle between showing and hiding the collapsible content.</p><div id="div2"><button class="accordion"><a href="#">Addq</a></button><div class="panel"> <p>Some collapsible content.

可折疊的 CSS 和 JS 在 Angular 應(yīng)用程序中不起作用
