title: Dynamically changing text/contrast of entire web site?
body: <p>This is using MVC 4 with Visual Studio 2013:</p>
  
  <p>I am wondering on how I would approach changing the text of my website dynamically through the click of a button. This is also the same for contrast. I am wondering if there's any plug ins or approaches I can take to do this?</p>
  
  <p>Heres an example of it being implemented correctly : <a href="http://www.bbc.co.uk/accessibility/guides/change_colours/#" rel="nofollow">http://www.bbc.co.uk/accessibility/guides/change_colours/#</a> 
  Giving different text sizes and contrasts etc. How would I approach this?
  My idea was to have a button that calls the same CSS sheet with the new colour /contracts. But that would mean I would need about 4-5 CSS sheets that are exactly the same with just the text/contrast changing. Is there a better approach to this?</p>
