The above code sets the animation duration to 8 seconds.
Example 2:
<!DOCTYPE html> <html> <head> <meta charset=" utf-8"> <meta name="author" content="http://www.php.cn/" /> <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>
The above code uses animation-duration to specify two animation durations for two animations respectively.
