在我的下拉菜单上,我想添加 transform css,这样当悬停时子菜单出现时会有一种向下翻转的效果。我已经将以下 css 添加到 .ht-main-navigation ul ul 但是它只会让整个菜单消失吗?谁能为此提供任何解决方案?提前致谢!

没有转换 css 的 jsfiddle - https://jsfiddle.net/w1emxfm5/

带有转换 css 的 jsfiddle - https://jsfiddle.net/n84u2xbL/

最佳答案

既然你想要一个“向下翻转”的效果,那么你只想转换scaleY()。并且您需要在默认状态下设置 scaleY(0) 的初始值,然后在悬停时转换为 scaleY(1)。您还需要切换 opacity 而不是 display: block/none 来隐藏/显示菜单,因为您不能 transition display 属性,如果您切换 display,菜单将隐藏/显示。
