问题描述
是否可以选择一个有焦点的元素,如 a:focus 或 input:focus,但在另一个元素上,如 div、li、span 或其他?
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?
如果不可能,如何用标签代替?我正在尝试修改 li 元素在聚焦时的高度,尝试使用 a,但高度不会改变.
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.
请求的信息:
你能不能解释一下你是如何把注意力放在李身上的?"
"Can you also explain how do you put focus on LI?"
通过 CSS 选择器 li:focus.请参阅 https://jsfiddle.net/s4nji/Rjqy5/.
Via css selector li:focus. See https://jsfiddle.net/s4nji/Rjqy5/.
推荐答案
这很简单:只需在通常不接收焦点的元素上添加一个 tabindex 属性即可.
That's simple: just add a tabindex attribute to the elements which normally don't receive focus.
