Change Text Size
The text size function built into the website uses javascript to change the text. Please note that the function only changes the size of the text in the main body of each page - the left hand menu and the content. It does not change the text size in the page header or footer.
It also creates a cookie in your web browser to remembers the text size you have selected. The cookie will be active for a period of 60 days, after which the website will return to the default size.
To change the size of the text to either 80%, 120% or 140% of the normal size, use the 'A's on the right hand side of the green header bar at the top of each page.

Use the A's at the top of each page to change the text size
Simply click on the size of text that you prefer. The current text size will be indicated by the 'hairpins' on each side of the relevant A.
