Contoh 1:
<!DOCTYPE html> <html> <head> <meta charset=" utf-8"> <meta name="author" content="//m.sbmmt.com/" /> <title>php中文网</title> <style type="text/css"> div{ width:100px; height:100px; background:red; position:relative; animation:theanimation infinite alternate; -webkit-animation:theanimation infinite alternate ; -moz-animation:theanimation infinite alternate ; -o-animation:theanimation infinite alternate ; -ms-animation:theanimation infinite alternate ; -webkit-animation-duration:8s; -moz-animation-duration:8s; -o-animation-duration:8s; -ms-animation-duration:8s; animation-duration:8s; } @keyframes theanimation{ 0%{top:0px;left:0px;background:red;} 25%{top:0px;left:100px;background:blue;} 50%{top:100px;left:100px;background:yellow;} 75%{top:100px;left:0px;background:green;} 100%{top:0px;left:0px;background:red;} } @-moz-keyframes theanimation{ 0% {top:0px;left:0px;background:red;} 25%{top:0px;left:100px;background:blue;} 50%{top:100px;left:100px;background:yellow;} 75%{top:100px;left:0px;background:green;} 100%{top:0px;left:0px;background:red;} } @-webkit-keyframes theanimation{ 0%{top:0px;left:0px;background:red;} 25%{top:0px;left:100px;background:blue;} 50%{top:100px;left:100px;background:yellow;} 75%{top:100px;left:0px;background:green;} 100%{top:0px;left:0px;background:red;} } @-o-keyframes theanimation{ 0%{top:0px;left:0px;background:red;} 25%{top:0px;left:100px;background:blue;} 50%{top:100px;left:100px;background:yellow;} 75%{top:100px;left:0px;background:green;} 100%{top:0px;left:0px;background:red;} } </style> </head> <body> <div></div> </body> </html>
Kod di atas menetapkan tempoh animasi kepada 8 saat.
Contoh 2:
<!DOCTYPE html> <html> <head> <meta charset=" utf-8"> <meta name="author" content="//m.sbmmt.com/" /> <title>php中文网</title> <style type="text/css"> div{ width:100px; height:100px; background:red; position:relative; animation:firstanimation infinite alternate,secondanimation infinite alternate; -webkit-animation:firstanimation infinite alternate,secondanimation infinite alternate; -moz-animation:firstanimation infinite alternate,secondanimation infinite alternate; -o-animation:firstanimation infinite alternate,secondanimation infinite alternate; -ms-animation:firstanimation infinite alternate,secondanimation infinite alternate; -webkit-animation-duration:5s,2s; -moz-animation-duration:5s,2s; -o-animation-duration:5s,2s; -ms-animation-duration:5s,2s; animation-duration:5s,2s; } @keyframes firstanimation{ 0% {left:0px;} 100% {left:200px;} } @-webkit-keyframes firstanimation{ 0% {left:0px;} 100% {left:200px;} } @-moz-keyframes firstanimation{ 0% {left:0px;} 100% {left:200px;} } @-o-keyframes firstanimation{ 0% {left:0px;} 100% {left:200px;} } @-ms-keyframes firstanimation{ 0% {left:0px;} 100% {left:200px;} } @keyframes secondanimation{ 0% {top:0px;} 100% {top:200px;} } @-webkit-keyframes secondanimation{ 0% {top:0px;} 100% {top:200px;} } @-moz-keyframes secondanimation{ 0% {top:0px;} 100% {top:200px;} } @-o-keyframes secondanimation{ 0% {top:0px;} 100% {top:200px;} } @-ms-keyframes secondanimation{ 0% {top:0px;} 100% {top:200px;} } </style> </head> <body> <div></div> </body> </html>
Kod di atas menggunakan tempoh animasi untuk menentukan dua tempoh animasi untuk dua animasi masing-masing.
