title: Accessing less properties
body: <p>I'm sorry, I think it's already been asked, but I don't know which keywords I should use, as I'm new to less.</p>
  
  <p>I need to do something like :</p>
  
  <pre><code>.class1 {
      top: 10%;
      height: 20%
   }
   .class2 {
      top: .class1-&gt;top + .class1-&gt;height + 10%;
      height: class1-&gt;height;
   }
  </code></pre>
  
  <p>Is it possible to do this without defining variables such as @class1top and @class1height ?</p>
  
  <p>Thanks for answers, or a redirection to this question if you can find one</p>
  
  <p>Have a good day :)</p>
