Accessibility means enabling people with disabilities or limited mobility to participate in activities that include the use of products, services and information, besides allowing the use of those by all segments of the population
We're talking about public vehicles with access to impaired persons, television with subtitles for people with hearing problems, among others. On the Internet, the term accessibility also refers to the W3C (content in portuguese) recommendations, which aim to allow everyone to have access to sites, regardless of having a disability or not.
These recommendations start with the text size and font color, location of the clickable areas, ease of availability of content and other suggestions relating to the coding of the pages (HTML and CSS, etc.).
The Web accessibility includes the following factors:
• Sites and Applications: developed so that people can perceive, understand, navigate and interact.
• Browsers, media players and tools: must have media technologies specially designated and intended for people with disabilities, allowing it to access Internet.
• Authoring tools and other technologies: blogs, twitter, instant messaging and other products used for production of Internet content.
The Portal CSNU has been designed to offer its content to all persons with disabilities. In the top menu there are buttons to increase and decrease the text size, and also to change the color, emphasizing content over the background of the screen. Thus, people can read and use more easily throughout the site.
