title: Concatenate strings in Less
body: <p>I think this is not possible, but I thought I ask in case there is a way. The idea is that I have a variable for path to web resource folder:</p>
  
  <pre><code>@root: "../img/";
  @file: "test.css";
  @url: @root@file;
  
  .px {
      background-image: url(@url);
  }
  </code></pre>
  
  <p>I get this as a result:</p>
  
  <pre><code>.px { background-image: url("../img/" "test.css"); }
  </code></pre>
  
  <p>But, I want the strings to combine into one string like this:</p>
  
  <pre><code>.px { background-image: url("../img/test.css"); }
  </code></pre>
  
  <p>Is it possible to concatenate strings together in Less?</p>
