延迟CSS转换2秒

Delay the CSS transition for 2 secs

本文关键字：2秒 转换 CSS 延迟      更新时间：2023-09-26

OK，我已经创建了一个按钮，当鼠标悬停在它上面时，它会显示一个菜单。一旦将鼠标从按钮上移开，菜单就会被隐藏。这是完美的，但菜单不应该消失，当我从鼠标移到菜单本身。也发生了,但我已经创建了一个使用css反弹效应使它更时尚,如果我尝试悬停鼠标在菜单上动画发生之前,再次得到隐藏菜单,因为菜单和按钮之间的差距在弹跳动作,所以我想延迟2秒的隐藏,所以即使有人继续按钮并试图移动菜单消失之前应该等待至少2秒。链接到小提琴

我不知道如果有必要涉及javascript或jQuery。但是，如果使用它们中的任何一个都可以实现，那么也没关系。

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

编辑:

可以指定多个延迟;每个延迟将应用于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，则缺失值被设置为初始值(0)。如果有更多的延迟，则简单地将列表截断到合适的大小。在这两种情况下，CSS声明仍然有效。

CSS的主要变化:

  1. 将LI的位置更改为相对位置并删除其子位置固定，以便LI的大小将包括其所有子位置;这一步是至关重要的，因为它将使li:hover始终工作，即使鼠标可以移出链接"Numbers";
  2. 在LI而不是子菜单上应用z-index，恐怕这应该更合理，因为我们希望整个菜单应该在顶部前面;
