用css做一个呼吸效果，然后让想闪烁的元素调用：
比如，我的div想呼吸
div.breatheDiv{height:500px
width:500px
background-color: #FF94A6
border-radius: 100%
webkit-animation: breathe 2000ms ease infinite
-moz-animation: breathe 2000ms ease infinite
-o-animation: breathe 2000ms ease infinite
animation: breathe 2000ms ease infinite
}
@-webkit-keyframes breathe{
0% {opacity:.2box-shadow:0 1px 10px rgba(255,255,255,0.1)}
100%{opacity:1box-shadow:0 1px 40px rgba(255,107,132,0.5)}
50%{opacity:1box-shadow:0 1px 80px #ff6b84}
}
@-moz-keyframes breathe{
0% {opacity:.2box-shadow:0 1px 10px rgba(255,255,255,0.1)}
100%{opacity:1box-shadow:0 1px 40px rgba(255,107,132,0.5)}

50%{opacity:1box-shadow:0 1px 80px #ff6b84}

最好的解决办法就是用个GIF动画代替，这样即使是最古老的浏览器都没有问题，而且运行效率与css3实现的动画不相上下。这要看你的网页侧重于哪种浏览设备。如果是主要用于移动设备如手机上的浏览器的，可以放心大胆地使用css3的特效，因为几乎所有智能手机上的浏览器都是支持css3标准的；如果是主要用于电脑的，则尽量避免使用css3中的新特性，改用最兼容、最稳妥的方法，因为它面对的是形形色色、标准极其不统一的多种浏览器；如果是手机和电脑都要兼顾到的网页，则也要坚持“就低不就高”的原则，在兼容性与炫酷之间选择前者。
