This site should be usable whatever you are reading it with. This page says what that means in practice.
What we do
Headings are used in order, images carry descriptions, and colours are checked for contrast against the background behind them. The site works at phone width and with a keyboard alone.
Known gaps
Some older articles predate these checks and have not been revisited yet. They are being worked through in date order.
Telling us
If something on this site is hard to use, the contact page reaches us, and a note about which page and which device is enough to start with.
