我在 :hover
css 上看到了建议只是 display:none
的答案.但这会使 div 在鼠标移动时闪烁.
I've seen answers suggesting just display:none
on the :hover
css. But that makes the div flicker when the mouse is moving.
添加 jsfiddle
display:none
会将元素从渲染树中取出,因此它会失去 :hover
状态立即,然后重新出现并再次获得 :hover
,消失,重新出现,等等......
display:none
will take the element out of the render tree, so it loses :hover
state immediately, then reappears and gets :hover
again, disappears, reappears, etc...
你需要的是:
#elem { opacity:0; filter:alpha(opacity=0); }
它将使该位置为空,因此不会出现闪烁.(演示 或 你的更新了)
It will leave the place empty, so no flickering will appear. (Demo or yours updated)
