我将这个CSS3动画用于编写代码。
HTML
<div class="heart heart1"></div>
<div class="heart heart2"></div>
CSS3
html, body{
width: 100%;
height: 100%;
min-width: 500px;
min-height: 500px;
overflow: hidden;
}
.heart {
position: absolute;
width: 100px;
height: 90px;
top: 50%;
left: 50%;
margin-top: -45px;
margin-left: -50px;
}
.heart:before,
.heart:after {
position: absolute;
content: "";
left: 50px;
top: 0;
width: 50px;
height: 80px;
background: #fc2e5a;
border-radius: 50px 50px 0 0;
transform: rotate(-45deg);
transform-origin: 0 100%;
}
.heart:after {
left: 0;
transform: rotate(45deg);
transform-origin :100% 100%;
}
.heart1{
animation: heart-anim 1s linear .4s infinite;
}
.heart2{
animation: pounding .5s linear infinite alternate;
}
.heart1:after, .heart1:before{
background-color: #ff7693;
}
@keyframes pounding{
0%{ transform: scale(1.5); }
100%{ transform: scale(1); }
}
@keyframes heart-anim {
46% {
transform: scale(1);
}
50% {
transform: scale(1.3);
}
52% {
transform: scale(1.5);
}
55% {
transform: scale(3);
}
100% {
opacity: 0;
transform: scale(50);
}
}

正如你所看到的那样工作正常,但是,如果我将确切的代码发布到我的本地服务器或jsfiddle,它将不再起作用:http://jsfiddle.net/40aydbfr/
我认为动画不是根据最佳实践制作的,因为它很容易打破。
那么,为什么它不能在codepen之外工作,如何让它更兼容浏览器兼容性。
PS:我正在使用Chrome。
答案 0 :(得分:1)
它不起作用,因为您缺少-webkit-
浏览器的供应商前缀。
它在codepen上工作的原因是,如果你单击CSS窗口上方的设置按钮,你会看到 -prefix-free 已启用,这意味着它会添加前缀自动。
Always check browser support, if something doesn't work
