Animate.css动画在动画完成后消失
我正在尝试构建一个每个列表项都有一系列动画的菜单。它可以工作,但是在动画之后,该项目再次消失。它看起来好像没有使用.Animated的Visible属性。您能给我任何解决此问题的指导吗?
<ul class="menu-ani-item">
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
<li class="animated">Hello World</li>
</ul>
.menu-ani-item {
li {
animation: slideInDown 2s;
visibility: hidden;
&:nth-child(1) {
animation-delay: 0s;
}
&:nth-child(2) {
animation-delay: 2s;
}
&:nth-child(3) {
animation-delay: 3s;
}
&:nth-child(4) {
animation-delay: 4s;
}
&:nth-child(5) {
animation-delay: 5s;
}
&:nth-child(6) {
animation-delay: 6s;
}
&:nth-child(7) {
animation-delay: 7s;
}
&:nth-child(8) {
animation-delay: 8s;
}
&:nth-child(9) {
animation-delay: 9s;
}
&:nth-child(10) {
animation-delay: 10s;
}
&:nth-child(11) {
animation-delay: 11s;
}
&:nth-child(12) {
animation-delay: 12s;
}
}
}
解决方案
如果您自己的动画没有按您希望的那样工作,我建议您定义该动画。如果我没记错的话,预定义的动画是这样的
@keyframes slideInDown {
from {
transform: translate3d(0, -100%, 0);
visibility: visible;
}
to {
transform: translate3d(0, 0, 0);
}
}
因此您的动画必须是:
@keyframes slideInDown {
from {
transform: translate3d(0, -100%, 0);
visibility: visible;
}
to {
transform: translate3d(0, 0, 0);
visibility: visible;
}
}
然后只需将animation-fill-mode: forwards;
添加到CSS中的li以保持可见性(这样您的CSS类似于):
@keyframes slideInDown {
from {
transform: translate3d(0, -100%, 0);
visibility: visible;
}
to {
transform: translate3d(0, 0, 0);
visibility: visible;
}
}
.menu-ani-item {
li {
animation: slideInDown 2s;
animation-fill-mode: forwards;
visibility: hidden;
...

您可能需要在关键帧中添加供应商前缀,以确保所有内容都能跨浏览器正常工作。您可以阅读有关here和here的更多信息。但在SCSS中,您可以定义一般供应商前缀,如here相关文章
