title: Does LESS have something comparable to the @content directive in Sass?
body: <p>I tried to convert a more "advance" mixin from SASS to LESS but unsuccessful. </p>
  
  <p>Here is the mixin:</p>
  
  <pre><code>.breakpoint(@point) {
    @if @point == really big{
      @media (max-width: 80em) { @content; } 
    }
    @if @point == mid {
      @media (max-width: 60em) { @content; }
    }
    @if @point == small {
      @media (max-width: 42em) { @content; } 
    }
  } 
  </code></pre>
  
  <p>and another one, I didn't touch this one:</p>
  
  <pre><code>@mixin keyframes( $animationName )
  {
      @-webkit-keyframes $animationName {
          @content;
      }
      @-moz-keyframes $animationName {
          @content;
      }
      @-o-keyframes $animationName {
          @content;
      }
      @keyframes $animationName {
          @content;
      }
  }
  </code></pre>
