“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, parkinsonâ€™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.”
