     扩展:

     @content:在sass3.2.0中引入, 可以用来解决css3中 @meidia 或者 @keyframes 带来的问题。它可以使@mixin接受一整块样式,接收的样式从@content开始

    //sass 样式               
    @mixin max-screen($res){
      @media only screen and ( max- $res )
      {
        @content;
      }
    }
    
    @include max-screen(480px) {
      body { color: red }
    }
    
    //css 编译后样式
    @media only screen and (max- 480px) {
      body { color: red }
    }

      使用@content解决@keyframes关键帧的浏览器前缀问题

    // 初始化变量
    $browser: null;
    // 设置关键帧
    @mixin keyframes($name) {
        @-webkit-keyframes #{$name} {
            $browser: '-webkit-'; @content;
        }
        @-moz-keyframes #{$name} {
            $browser: '-moz-'; @content;
        }
        @-o-keyframes #{$name} {
            $browser: '-o-'; @content;
        }
        @keyframes #{$name} {
            $browser: ''; @content;
        }
    }
    
    // 引入
    @include keyframes(scale) {
        100% {
            #{$browser}transform: scale(0.8);
        }
    }
    
    // css编译后
    @-webkit-keyframes scale {
        -webkit-transform: scale(0.8);
    }
    @-moz-keyframes scale  {
       -moz-transform: scale(0.8);
    }
    @-o-keyframes scale  {
        -o-transform: scale(0.8);
    }
    @keyframes scale  {
        transform: scale(0.8);
    }
