title: css @font-face in ubuntu doesn't work
body: <p>I developed the web-page under Windows. It has such folders:</p>
  
  <pre><code>wwwroot
  wwwroot/css
  wwwroot/fonts
  </code></pre>
  
  <p>and files</p>
  
  <pre><code>wwwroot/css/main.css
  wwwroot/fonts/fontaaa.otf
  </code></pre>
  
  <p>main.css file has such a code:</p>
  
  <pre><code>@font-face
  {
      font-family : 'fontaaa';
      src         : url("../fonts/fontaaa.otf");
  }
  </code></pre>
  
  <p>and it sees the font under Windows on my localhost.
  Everything is perfect, so I uploaded my project to the linux server.
  Everything works fine (the page loads, styles are OK), but the font <code>fontaaa.otf</code> is <strong>not displayed</strong>. What is the problem? Spent a lot of time to figure out.</p>
  
  <p>P.S. I've never used <code>@font-face</code> before.</p>
  
  <p>P.S.S. the font was downloaded from Internet (was not in the Windows fonts folder).</p>
