我做了一些不错的汉堡包效果,这些日子在移动导航栏的网站上非常普遍。
所以,当有人点击汉堡包时,它会完美地转动X(当添加“开放”类时)但是当班级移除动画时会发生奇怪的变化,请通过以下代码观看效果:
HTML:
<div id="hamburger">
<span></span>
<span></span>
<span></span>
</div>
CSS:
#hamburger {
float: left;
width: 20px;
height: 25px;
position: relative;
}
#hamburger span {
width: 100%;
height: 3px;
border-radius: 5px;
background: #000000;
position: absolute;
display: block;
-webkit-transform: rotate3d(0, 0, 1, 0deg);
-moz-transform: rotate3d(0, 0, 1, 0deg);
-o-transform: rotate3d(0, 0, 1, 0deg);
transform: rotate3d(0, 0, 1, 0deg);
}
#hamburger span:nth-child(1) {
top: 0;
-moz-transition: top 0.3s ease-in-out, -moz-transform 0.3s ease 0.3s;
-o-transition: top 0.3s ease-in-out, -o-transform 0.3s ease 0.3s;
-webkit-transition: top 0.3s ease-in-out, -webkit-transform 0.3s ease;
-webkit-transition-delay: 0s, 0.3s;
transition: top 0.3s ease-in-out, transform 0.3s ease 0.3s;
}
#hamburger span:nth-child(2) {
top: 7px;
opacity: 1;
-moz-transition: opacity 0.3s ease-in-out;
-o-transition: opacity 0.3s ease-in-out;
-webkit-transition: opacity 0.3s ease-in-out;
transition: opacity 0.3s ease-in-out;
}
#hamburger span:nth-child(3) {
top: 14px;
-moz-transition: top 0.3s ease-in-out, -moz-transform 0.3s ease 0.3s;
-o-transition: top 0.3s ease-in-out, -o-transform 0.3s ease 0.3s;
-webkit-transition: top 0.3s ease-in-out, -webkit-transform 0.3s ease;
-webkit-transition-delay: 0s, 0.3s;
transition: top 0.3s ease-in-out, transform 0.3s ease 0.3s;
}
#hamburger.open span:nth-child(1) {
top: 7px;
transform: rotate3d(0, 0, 1, 45deg);
}
#hamburger.open span:nth-child(2) {
opacity: 0;
}
#hamburger.open span:nth-child(3) {
top: 7px;
transform: rotate3d(0, 0, 1, -45deg);
}
Javascript:
$(document).ready(function () {
$('#hamburger').click(function () {
$(this).toggleClass('open');
});
});

你能帮帮我吗?
答案 0 :(得分:4)
您可以通过执行以下操作来更正删除动画:
.open
选择器中设置转发转换的设置。添加.open
课程后,第二个孩子的opacity
会在没有任何延迟的情况下过渡0.3秒。与此同时,其他两个孩子的top
位置也正在转变。然后在0.3s
延迟后,第1个和第3个孩子的transform
被转换。这样可以使顶部和底部杆向下移动然后旋转。transition
设置。也就是说,在第一个和第三个孩子的transform
过渡时间为0.3s
,同时这两个孩子的top
和第二个孩子的opacity
已经过渡延迟0.3s
之后。当元素丢失.open
类时,此设置将适用,因此会产生相反的效果。
$(document).ready(function() {
$('#hamburger').click(function() {
$(this).toggleClass('open');
});
});
