标签: javascript jquery html css3 animation

基本上我收到了改变codepen的帮助,并对最终结果很满意,但是当我试图在html网页上实现它时,它没有正确呈现,我不确定它出错的地方,这是代码笔http://codepen.io/anon/pen/hsepG

的链接

这是我尝试的实施:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
<title>test</title>
<style>
@mixin animate($animation, $duration, $repeat, $easing) {
-webkit-animation: $animation $duration $repeat $easing;
   -moz-animation: $animation $duration $repeat $easing;
    -ms-animation: $animation $duration $repeat $easing;
        animation: $animation $duration $repeat $easing;
}

@mixin keyframes($name) {
@-webkit-keyframes #{$name} {
    @content; 
}
@-moz-keyframes #{$name} {
    @content;
}
@-ms-keyframes #{$name} {
    @content;

}

我的Css应该在单独的样式表中吗?

您的codepen使用的是SCSS,而不是直接的CSS。请参阅http://sass-lang.com

因此,要在您自己的网页上使用它,您需要编译SCSS,或者从代码笔中复制已编译的CSS。要从codepen中获取已编译的CSS,请单击(SCSS)
