4.5 million people in The Netherlands do not fully participate online. That is 25% of the population. It is difficult for them to read and use websites. Full-fletched web accessibility means that people with a challenge should be able to read content on websites, understand it and use it the way they like. They should be able to navigate with the content and to communicate about it.
Making your website accessible also implies that you reconsider your page design and structure, because it doesn’t stop by only making your content accessible. Web accessibility should primarily focus on creating value for everybody, with or without a challenge.
