title: Resize logo on mobile when using Twitter Bootstrap
body: <p>I am working on a website that has a log size of 320x150 and looks really well on a resolution bigger than 600px, but if it`s lower it starts stacking up.</p>
  
  <p>How can edit bootstrap to use a smaller logo if the resolution of the browser is smaller the 600 px? </p>
  
  <p>Thank you</p>
