看了下，应该是css下面这段不起作用：@-webkit-keyframes sparkle { from {background-position:0 0;} to {background-position:0 -64px;} } @-moz-keyframes sparkle { from {background-position:0 0;} to {background-position:0 -64px;} } @-o-keyframes sparkle { from {background-position:0 0;} to {background-position:0 -64px;} } @keyframes sparkle { from {background-position:0 0;} to {background-position:0 -64px;} }
IE和360都不行，只有火狐正常，test.html
