代码如下

@keyframes fade {
    from {        
    opacity: 1.0;    
    }
    50% {        
    opacity: 0.4;    
    }
    to {        
    opacity: 1.0;    
    }
}
@-webkit-keyframes fade {    
    from {        
    opacity: 1.0;    
    }
    50% {        
    opacity: 0.4;    
    }
    to {        
    opacity: 1.0;    
    }
}
.headerBox {    
    color: #fff;    
    padding: 10px;    
    font-size: 15px;    
    height: 60px;    
    animation: fade 600ms infinite;    
    -webkit-animation: fade 600ms infinite;
}

给div设置headerBox 样式即可
