title: Weird Error on bootstrap
body: <p>I'm using bootstrap for a long time. I'm noticing a weird error today. I'm opening mozilla console and there at least hundred errors showing on twitter-bootsrap source. then I tried to insert bootsrap cdn, but still the same errors. Here is a list of some errors: </p>
  
  <pre><code>Unknown pseudo-class or pseudo-element '-webkit-inner-spin-button'. 
  Ruleset ignored due to bad selector.
  
  Expected color but found 'auto'.  Expected color but found
  '-webkit-focus-ring-color'.  Expected end of value but found
  '-webkit-focus-ring-color'.  Error in parsing value for 'outline'. 
  Declaration dropped.
  
  
  Expected end of value but found '\9 '.  Error in parsing value for
  'width'.  Declaration dropped.
  
  Error in parsing value for 'background-image'.  Declaration dropped.
  </code></pre>
  
  <p>Is there anything wrong with bootstrap?</p>
