Question

在我的下拉菜单中，我想添加变换css，这样当子菜单出现在悬停时会出现一种下翻效果。我已将以下css添加到.ht-main-navigation ul ul但是它只是让整个菜单消失了？任何人都可以提供任何解决方案吗？提前谢谢！

没有变换css的jsfiddle - https://jsfiddle.net/w1emxfm5/

jsfiddle with transform css - https://jsfiddle.net/n84u2xbL/

转换css

                        -webkit-transform: scale(1,0);
    -moz-transform: scale(1,0);
    transform: scale(1,0);
    -webkit-transform-origin: top;
    -moz-transform-origin: top;
    transform-origin: top;
    -webkit-transition: all .3s ease-in-out;
    -moz-transition: all .3s ease-in-out;

Answer 1

由于您需要“向下翻转”效果，因此您只想转换scaleY()。您需要将scaleY(0)的初始值设置为默认状态，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，因为您无法transition display属性，菜单只会隐藏/显示你正在切换display。
