“Did you know that up to 25% of all visitors on your website have some kind of accessibility problem. Some of your users may be blind, deaf, dyslectic, has learning disabilities or motoric disabilities such as schlerosis, parkinson’s disease, etc. A so-called functional disability.
But how about users with a technical disability: Wireless devices, slow internet connections, old browsers, feed readers, etc. These should be considered as well, as there are probably more people with technological disability than functional disability.
25% of all web users have some kind of accessibility problem. That is a claim from the Danish Center for Accesibility.”
