title: Stretching the image for different screen sizes
body: <p>I wasn't too sure on what to search for my answer. Basically I have a design made, and the header can be seen <a href="http://cl.ly/2o1v2H3B2B2w2k423B3Q" rel="nofollow">here</a>.</p>
  
  <p>The width of the document there is 1200. I can get hold of a bigger version for a width of up to 2560, but how should I go about using the image? Should I use CSS media queries and use different images for a certain screen size? Note: this isn't a mobile site design; I just need to function with all computer screens.</p>
  
  <p>I'm sorry if this has been asked/answered before but as I said I wasn't 100% sure on what to search.</p>
