Colors and contrast
To aid readability, we have tried to ensure a good level of contrast between text and background colors. On certain browsers you can override our design and use your own preferred color scheme. Consult your browser's help pages for instructions on how to change background and font colors.
Accessibility and technologies
Where necessary, code will be implemented to allow the website to degrade gracefully so that the site is still usable. These instances will occur if certain technologies or presentation elements, such as CSS or images, are unavailable within the user’s browser.
Please email us if you encounter any problems using the site, so we can work to get it fixed as soon as possible.
