The WCAG, or Web Accessibility Content Guidelines , is a document that stipulates the digital accessibility standards that websites must follow. The first version (1.0) was released in 1999. After that, the guidelines were reformulated in 2008, and last year, they underwent a new update, which is not yet available in Portuguese.
These recommendations were all developed by W3C, the World Wide Web consortium. In this text, we will take as a starting point the most recent document in Portuguese, that is, WCAG 2.0, produced in 2008.
The guidelines are very useful, because with them, it is possible to cell phone number list have direction and know which ways to build an accessible website . However, at first, the document language, which is aimed especially at programmers, may seem complex and difficult to understand. But do not worry! In this text, you will understand how the accessibility guidelines were thought out logically, and from that, you will quickly understand them better.
It is important to keep in mind that when it comes to digital accessibility, the audience to be reached is very diverse . Therefore, it requires several different measures. To think about the accessibility of blind people, for example, alternative descriptions are essential. In the case of color blind people, contrast is an essential issue . Most people with hearing impairment require translation into sign languages. And these are just a few examples that can be cited. Therefore, WCAG 2.0 is an extensive document that contains several specifications, to cover all audiences in the most complete way possible.

The following infographic explains in a very didactic way how the document is organized. It is divided into four principles, which have recommendations. The latter, in turn, are evaluated using success criteria, achieved through specific techniques.
blue background image. In the center is an infographic, which is organized using slots, like a lego. In the largest piece, it says: principles. They progressively decrease, where it is written respectively: recommendations, success criteria and techniques. The pieces are square and alternate between yellow and orange.
The principles
Perceivable : according to this principle, content must be presented in more than one way. For this, an alternative description of images, subtitles in videos or other types of multimedia, and HTML code that can understand screen readers are requirements.
With these measures, the website's content will not be transmitted in a single way, which makes it visible to an audience that would previously have been unable to access it.
Operable : as the name suggests, a properly operable website is one in which all users are able to carry out various operations without access barriers. Therefore, the HTML coding must be adjusted to allow keyboard navigation. Furthermore, the page speed must be balanced: not too fast, not too slow and structuring the headers in an organized way is also necessary. Finally, the use of devices that are a trigger for epileptic attacks should be avoided: excessive colors and lighting, or the excessive use of pop-ups are usually harmful in this sense.
Understandable : the third principle concerns above all the textual content of websites. In addition to an appropriate choice of fonts, it is necessary to avoid specific expressions and write sentences clearly and objectively. Measures like this make the site accessible especially for people with dyslexia or intellectual disabilities , but they can also be very useful for those who are not part of a certain context, or have reading difficulties for some reason.
Robust : The last concept concerns website coding. The WCAG stipulates that HTML must be aligned to the point of being able to run existing assistive technologies and also to make the website navigable using the keyboard, which in the latter case is essential for people with motor disabilities.
