正如King King所说，您必须添加浏览器特定的前缀。这应该涵盖大多数浏览器：
@keyframes flickerAnimation { 0% { opacity:1; } 50% { opacity:0; } 100% { opacity:1; }}@-o-keyframes flickerAnimation{ 0% { opacity:1; } 50% { opacity:0; } 100% { opacity:1; }}@-moz-keyframes flickerAnimation{ 0% { opacity:1; } 50% { opacity:0; } 100% { opacity:1; }}@-webkit-keyframes flickerAnimation{ 0% { opacity:1; } 50% { opacity:0; } 100% { opacity:1; }}.animate-flicker { -webkit-animation: flickerAnimation 1s infinite; -moz-animation: flickerAnimation 1s infinite; -o-animation: flickerAnimation 1s infinite; animation: flickerAnimation 1s infinite;}<div >Loading...</div>
