使用：聚焦伪类对li或除a，输入，按钮等之外的其他元素 [英] using :focus pseudo class on li or other element else than a,input,button, etc

问题描述

是否可以选择一个聚焦的元素，如：focus或input：focus，而另一个元素，如div，li，span或else？

如果不可能，如何替换标签？
我试图修改li元素的高度，当它集中，尝试a，但高度不会改变。

请求的信息：

你也可以解释一下如何把重点放在LI上？

通过css选择器 li：focus 。请参阅 https://jsfiddle.net/s4nji/Rjqy5/ 。

解决方案

这很简单：只需向通常不接收焦点的元素添加 tabindex 属性。 / p>

Is it possible to select an element that is focused, like a:focus or input:focus, but on the other element, such as div, li, span or else?

If it's not possible, how can it be substituted with a tag? I am trying to modify height of a li element when it's focused, tried with a, but the height won't change.

Requested Info :

"Can you also explain how do you put focus on LI?"

Via css selector li:focus. See https://jsfiddle.net/s4nji/Rjqy5/.

解决方案

That's simple: just add a tabindex attribute to the elements which normally don't receive focus.
