好的，所以我创建了一个按钮，将鼠标悬停在它上面时会显示一个菜单。一旦鼠标离开按钮，菜单就会被隐藏。这是完美的，但是当我从鼠标移到菜单本身时，菜单不应该消失。这也在发生，但我使用 css 创建了一个反弹效果，使其更时尚一点，如果我尝试在动画发生之前将鼠标悬停在菜单上，菜单会再次隐藏，因为菜单之间的差距和按钮在弹跳动作期间，所以我想延迟隐藏 2 秒，这样即使有人继续按钮并尝试移动菜单，它也应该等待至少 2 秒才能消失。链接到小提琴

我不知道是否有必要涉及 javascript 或 jQuery。但是，如果使用它们中的任何一个都可以实现，那么它也很好。

也许你想要transition-delay：https ://developer.mozilla.org/en-US/docs/CSS/transition-delay

编辑：

您可以指定多个延迟；每个延迟都将应用于由 transition-property 属性指定的相应属性，该属性充当主列表。如果指定的延迟少于主列表中的延迟，则将缺失值设置为初始值 (0s)。如果有更多延迟，列表会被简单地截断为正确的大小。在这两种情况下，CSS 声明都保持有效。

major CSS changes:

  1. change the LI's position to relative and remove its children's position fix so that LI's size will include all of its children; This step is critical, since it will make the li:hover works all the time even the mouse could move out of link "Numbers";
  2. apply z-index on the LI rather than on the sub menus, I'm afraid this should be more rational, since we want the whole menu should be on the top front;
