title: On which operating systems or browsers are CSS font-family names case-sensitive
body: <p>According to <a href="http://reference.sitepoint.com/css/font-family" rel="noreferrer"><strong>sitepoint</strong></a> (<em>a source I typically highly trust</em>) when specifying <code>font-family</code> names some Operating Systems/Browsers <strong><em>may</em></strong> be <strong>case-sensitive</strong>.</p>
  
  <p>I've typically always used mixed-case values but I'm wondering if lower-case values will work just the same?</p>
  
  <p>I don't have an overwhelming preference either way - but I'd hate for a page to render differently because I typed a lower-case <code>"v"</code> vs. <code>"V"</code> somewhere in a CSS file.</p>
  
  <p>e.g. are there any known cases where 2 divs with the <code>foo</code> and <code>bar</code> classes below would actually render with a different font?</p>
  
  <pre><code>div.foo{
    font-family:Verdana, Arial, Helvetica;
  }
  
  div.bar{
    font-family:verdana, arial, helvetica;
  }
  </code></pre>
