  <p>I'm just playing around with a sass version of <a href="http://www.the-art-of-web.com/css/nth-child-selectorhttp://www.the-art-of-web.com/css/nth-child-selector/">this example</a>.  I'm not sure that I'm a fan of ~ but I really like the variables of sass.
  <div id="stuff"></div>
  <pre>
$class-box: box
  
@for $i from 2 through 99 
  .tight.#{$class-box}#{$i}:hover ~ div:nth-child(#{$i}n)
    background: #ccf
  .tight.#{$class-box}#{$i} ~ div:nth-child(#{$i}n)
    background: #eee
    </pre>
</body>

  border: 1px solid #aaa
