There are over 8.5 million people registered as disabled in the UK so it makes sense to have a website that all these people can use. Accessibility is not just about disability but can be applied across a broad spectrum of users e.g. those who do not have the latest computers, those who don't have broadband, those who view websites on mobile phones or PDAs. Accessibility is about making your website available to the widest possible audience.
Webrex can help you design a website that is truly accessible.
