在SASS写Mixins时有没有办法逃脱@?

我正在尝试为css3中的动画编写mixin。 css3中的动画需要@keyframe。但SASS(和其他声明)中的mixin声明也以@开头。就像@mixin,@ for等...所以我试图为动画编写mixin(我试图在mixin中进行所有自动化)是为了传递给CSS时将@keyfram转义为SASS解释@keyframe的@。有可能这样做吗?

示例:

@mixin animation(
//variables :
$mykeyframe:mykeyframe,
$prop1:background,
$value1-i:white,
$value1-e:red,
$prop2:color,
$value2-i:black,
$value2-e:white,
$prop3:font-weight,
$value3-i:400,
$value3-e:bold,
$time:5s,
$iteration-count:1,
$timing-function:linear,
$delay:0s,
$direction:normal,
$play-state:running
)

{//HERE'S THE PROBLEM :
  @keyframes $mykeyframe{
    0%{$prop1:$value1-i; $prop2:$value2-i; $prop3:$value3-i}
    100%{$prop1:$value1-e; $prop2:$value2-e; $prop3:$value3-e}
  }

  -webkit-animation: $mykeyframe $time $iteration-count; /* Chrome, Safari 5+ */
  -moz-animation: $mykeyframe $time $iteration-count; /* Firefox 5-15 */
  -o-animation: $mykeyframe $time $iteration-count; /* Opera 12.00 */
  animation: $mykeyframe $time $iteration-count; /* Chrome, Firefox 16+, IE 10+, Opera 12.10+ */

  /* Chrome, Firefox 16+, IE 10+, Opera 12.10+ */
  animation-timing-function: $timing-function;
  animation-delay: $delay;
  animation-direction: $direction;
  animation-play-state: $play-state;
  /* Safari and Chrome: */
  -webkit-animation-timing-function: $timing-function;
  -webkit-animation-delay: $delay;
  -webkit-animation-direction: $direction;
  -webkit-animation-play-state: $play-state;
}

即使在SASS中的mixin(@mixin)和条件(@for@if等)指令以符号@开头,您仍然可以将它用于其他不属于SASS库的关键字,如ifmixin等。

所以,你仍然可以这样做:

@mixin animation($mykeyframe:mykeyframe) {
  @keyframes $mykeyframe {


  }
}

body {
  @include animation(someframe);

}

这会产生:

body {
  @keyframes someframe {}
}
