css3转换未在切换按钮上触发[重复]

Question

这是我的第二个问题！ 我也搜索了问题，但没有任何帮助。 我有过渡的问题。当在移动视图上选中切换按钮时，我正在尝试对菜单应用 300 毫秒的过渡；我在 .menu 类中尝试使用负值是徒劳的。现在，这样做菜单向上滑动，但我希望它向下滑动，似乎没有任何帮助。我也尝试过使用 z-index，但似乎没有任何效果。 我真的不知道该怎么办。任何可以向我发送正确方向的帮助将不胜感激！

Answer 1

#menuToggle:checked ~ header .menu {
    display: block;
    top;
    66px;
}

应该是

#menuToggle:checked ~ header .menu {
    display: block;
    top: 66px;
}

Answer 2

@media screen and (min-width:600px) {
#logo {
float: left;
}
.menu {
width: 100%;
height: 70px;
position: absolute;
display: block;
}
.menu-icon {
display: none;
}
header {
height: 70px;
background-color: #FFF;
margin: auto;
width: 100%;
}
nav {
height: -66px;
width: 100%;
}
nav ul {
background-color: #FFF;
display: inline;
float: right;
padding: 0.55em 2em 0 0;
height: inherit;
}
nav ul li {
display: inline;
margin: 0.2em auto;
}
nav ul li:hover {
background-color: #FFF;
}
nav ul li a {
padding: 0 2em;
}
