What is Web Content Accessibility Guidelines (WCAG)?

Abbreviation WCAG stands for Web Content Accessibility Guidelines. This is a standard created in cooperation with organisations from all over the world to satisfy the needs of people with disabilities all around the globe. That’s why these shared guidelines should be met by the international community. Implementing them is up to people involved in the process of web content production.

For now WCAG 2.0 is the latest version, which contains 12 guidelines in accordance with four main principles:

  • perceivable
  • operable
  • understandable
  • robust

All adjectives refer to content, information and UI components.

How to make your website more accessible?

Web content can be presented in different forms: text, image, audio, video. All content types should be accessible as much as possible to all people, including Internet users with visual, auditory and motor disabilities.

If you have pictures or photos on your website, which serve more than a decorative function and cover important information, then you should write ALT attribute for them that briefly conveys the essence and main aim of those pictures. Screen readers will voice your ALT text to visually impaired people. By the way, having ALT attribute improves your SEO, as it is taken into consideration by search engines when showing results of image search.

If you site contains prerecorded video or audio-only media, make this content accessible for deaf people too. Create captions, audio descriptions, subtitles or even sign language interpretation if your video/audio contains human speech.

Provide your users with ways to define on what part of site they are and navigate to the content they need. Make all your website functionality operable from a keyboard to ease life for those who find it hard to use a mouse and touchpad. Make sure users can skip to all menus and content with keystrokes and mouse clicks equally well. This extra option also helps out non-disabled users whose mouse is temporarily broken or ran out of batteries. So you’ll enhance user experience for everyone.

Besides these main aspects, there are much more ways to reach web accessibility. On w3.org you can find very useful list of techniques to meet WCAG 2.0.
