Accessibility is the term used to describe whether a website can be used by people of all abilities / disabilities on a range of differing digital devices.
The way a person perceives information is affected by their ability / disability along with how they navigate between website pages. A website can only be classed as accessible if all people, including the elderly and disabled, can use it.
