Visual Styles

(Accesible at the top right of the page via the universal access icon - Universal Access icon) When you choose a new design theme (Default Theme or Contrast Theme) by clicking on the image for high contrast or normal contrast (either High Contrast or normal Contrast), a cookie with the name of the theme is stored on your web browser so that the next time you visit, the site is presented with the same visual appearance.

You can also change the font size by using the "Bigger Reset Smaller" also accessible via at the top right of the screen via the universal access icon -Universal Access icon. The font size will also be remembered via a cookie between sessions and pages so you will come back to the site with the previous settings.

Please note that external content inserted into this website e.g. The Twitter Feed on the home page, the Google Calendar and Google maps, does not change contrast with this functionality - it is beyond the capabilities of the site and the responsibility of third parties.
