This web site is coded using HTML5 and relies on its features.

We have tested most of our pages with the following browsers (with apologies to Apple users):

• Firefox version 107.0 (64-bit) on Windows 10
• Microsoft Edge version 107.0.1418.42 (64-bit) on Windows 10
•  
• Firefox version 107.0.7 on Android version 9
• Samsung Internet version 19.0.1.2 on Android version 9

On some smart phones with smaller displays, browsers may automatically change or increase the displayed text size. Most of the time this works OK, but sometimes our web pages will display incorrectly. Switching the browser to "Desktop Mode" will usually fix this problem.
