title: Remove background arrow from date input in Google Chrome v20
body: <p>Since Google Chrome v20 a new calendar has been added to date inputs. The issue with this is that I'm using javascript to create my own calendar and I have an icon already in the same position as the default chrome arrow.</p>
  
  <p>I was wondering how can I remove the arrow background?</p>
