title: How to change font and background colour of a site throughout with a click of a button
body: <p>I would like my users to be able to change the colour of their background and font colour using 'accessibility' buttons. The site would need to remember this as the user navigates around.</p>
  
  <p>An example can be seen here:</p>
  
  <p><a href="https://www.shop4support.com/" rel="nofollow">https://www.shop4support.com/</a></p>
  
  <p>Click the coloured letters to the left of the 'Report this page button' at the very top.</p>
