title: Get prefixes of css filters with Modernizr
body: <p>I'm trying to use the Modernizr.prefixed() function to avoid writing all the vendors code in my JS but it doesn't seems to work.
  I would like to use it for css filters, here is my code:
  <code>Modernizr.prefixed('filter') // returns 'filter' on Chrome which actually needs '-webkit-filter'</code></p>
  
  <p>I already looked at the source code of Modernizr but it didn't helped (<a href="https://github.com/Modernizr/Modernizr/blob/master/feature-detects/css/filters.js" rel="nofollow">https://github.com/Modernizr/Modernizr/blob/master/feature-detects/css/filters.js</a>).</p>
  
  <p>Notice that the feature detection for filters is present in my Modernizr build.</p>
  
  <p>Thank you!</p>
