Column explainations

HTML
Given the complexity of accessibility testing, I've just used an automated test, it is by no means a comprehensive test!
CSS
Could have been slightly subjective, but most fell into one layout type or another.
Encoding
Interesting from the point of view of displaying macrons used for Māori.
Size
Given the state of New Zealand's boardband, I thought it would be interesting to see.
