Accessibility

We want this site to be accessible by everyone.

We've taken care to remove obstacles that may stop anyone from using it. We hope it works for you - and would welcome your feedback and comments.

Following is a description of specific features for people with visual impairment, and for those who prefer to use the keyboard rather than a mouse.

Features for visually impaired users

To make text easier to read, it can be increased in size.

On Windows or Linux computers this is typically done by pressing Ctrl + (and Ctrl - to reduce the text size) and on Mac computers by pressing ⌘ +, i.e. the Apple key and + (and ⌘ - to reduce the text size).

On mobile devices with touch screens, the size of the page can be changed by a ‘zoom’ gesture on the screen (placing two fingers on the screen and moving them apart) and a ‘pinch’ gesture to zoom out.
