我有一个页面有几个 <div>容器。
如何在页面加载时将焦点放在其中一个上，以便用户可以使用箭头键滚动(甚至 SPACE 滚动)而无需单击 div第一？
我试过:
<div id="main" autofocus>
但是autofocus似乎不适用于非输入 div .

这可能是一个解决方案，但浏览器地址栏会显示 id http://example.com/#main我不想要的:
<body onload="location.hash = 'main';">
<div id="main">content</div>
</body>
_
示例:当您打开 https://en.wikipedia.org/wiki/Main_Page ，您可以立即使用向下箭头 键或空格键 进行滚动，而无需点击任何地方。
最佳答案
您可以使用 JavaScript 来聚焦元素，并使用 tabindex 来聚焦元素。
document.querySelector(".focus").focus();.focus {
height: 100px;
width: 100px;
overflow: scroll;
}<div>Hello</div>
<div>Another div</div>
<div class="focus" tabindex="0">Lorem Ipsum is simply dummy text of the printing and typesetting industry.
