To see examples of what types of features are required within the compliance Levels A and AA, select each below:
The first, most basic level of accessibility compliance is called Level A. An example of a Level A accessibility feature on a web page is alternative text. Alternative text appears when your mouse hovers over an image. It’s important to use appropriate text when describing an image so that screen reader technology can describe the image to a person with vision loss.
The second, more extensive level of accessibility is called Level AA. An example of a Level AA accessibility feature on a web page is properly named headings and labels, which enable people using screen reader technology to scan through the information on a web page efficiently.
For example, to quickly identify what stories are on the home page of a newspaper, a screen reader can search just the headings for each story. Properly labelled headings allow the screen reader to tell when one article stops and the next begins. If this is not done, every individual article will be read as one story.
Each header should be labelled with the news article’s subject. This allows users to easily find the information they want.
