Accessibility Guide for attention deficit
The list of 53 Input Purposes for User Interface Components are used as the basis for the programmatic definition of the purpose for each common input field that collects user data.
For screen readers to work properly, the autocomplete attribute values must be true and applied correctly.
Inaccessible content stems from missing autocomplete values in form fields. In the absence of the necessary autocomplete attribute values, screen readers will not read the identified autocomplete form fields.
When screen readers are unable to adequately notify users about the requirements for form field interaction, users cannot successfully navigate forms.
What this Accessibility Rule Checks
The purpose of each user-information-collecting input field can be established programmatically when:
- The input field fulfills a purpose specified in the Input Purposes for User Interface Components section, and
- The content is implemented using technologies that provide support for determining the desired meaning of form input data.
Ensure that the text spacing specified by style attributes is modifiable using custom stylesheets.
When lines of text are single-spaced, many people with cognitive difficulties have difficulty following them. Providing spacing between 1.5 and 2 makes it easier for them to begin a new line after finishing the previous one.
What this Accessibility Rule Checks
Text line spacing must be modifiable by custom stylesheets.
The screen orientation (such as portrait or landscape) of mobile applications should not be restricted to a single mode. Users should be able to shift the orientation of their device between portrait and landscape without losing readability. Additionally, upon opening a page, it should appear in the current orientation of the user.
Users of assistive technologies may not have access to orientation features on their devices or assistive technologies.
What this Accessibility Rule Checks
Unless a specific display orientation is important, content does not confine its view and functionality to a single display orientation, such as portrait or landscape.
