title: CSS "properties of .x" syntax
body: <p>Is it possible to add additional rules to a css block when using a "{ (properties of x) }" selector? </p>
  
  <p>I looked at references but I can't find anything related to "properties of x". A link would be wonderful. I tried the following two combinations, but neither worked:</p>
  
  <pre><code>.dock li { (properties of grid_2; display:inline; background-color:#666; ) }
  .dock li { display:inline; background-color:#666; (properties of grid_2) }
  </code></pre>
  
  <p>Many thanks!</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Apparently I misread an article and thought that such a syntax existed. I thought one could create a class and let it inherit the properties of another using such syntax, which is evidently not the case.</p>
