The World Wide Web Consortium (W3C) has announced a new standard to make sites more accessible to older and disabled people.
Version 2.0 of the Web Content Accessibility Guidelines (WCAG) will apply to text, images, audio and video.
It also covers web applications and is said to give developers more flexibility than the old guidelines.
According to the consortium, WCAG 2.0 should also be easier to understand and use.
The guidance is designed to address barriers encountered by people with visual, hearing, physical, cognitive and neurological disabilities and older people with access needs.
