Accessibility

All elements on a page should be contained in a landmark element. This helps users of AT quickly navigate a page. HTML5 provides built in landmark elements such as main, nav, aside, header, footer.

Keyboard access to a website is key to the usability of your site. All interactions and information that can be accessed with a mouse must be accessible with just a keyboard.

Name, Role, Value> Name, Role, Value # For all user interface components (including but not limited to: form elements, links and components generated by scripts), the name and role can be programmatically determined; states, properties, and values that can be set by the user can be programmatically set; and notification of changes to these items is available to user agents, including assistive technologies.

Flashing is generally a bad idea. It can cause all sorts of issues, from seizures to motion sickness. If you absolutely must have a flashing element there are a few things to consider.

The Americans with Disabilities Act (ADA) is a federal civil rights law that prohibits discrimination against people with disabilities in everyday activities. The ADA prohibits discrimination on the basis of disability just as other civil rights laws prohibit discrimination on the basis of race, color, sex, national origin, age, and religion.

Businesses and state and local governments have flexibility in how they comply with the ADA’s general requirements of nondiscrimination and effective communication. But they must comply with the ADA’s requirements.

When websites and web tools are properly designed and coded, people with disabilities can use them. However, currently many sites and tools are developed with accessibility barriers that make them difficult or impossible for some people to use.

Web accessibility means that websites, tools, and technologies are designed and developed so that people with disabilities can use them. More specifically, people can: perceive, understand, navigate, and interact with the Web contribute to the Web Web accessibility encompasses all disabilities that affect access to the Web, including:

When Congress enacted the ADA in 1990, it intended for the ADA to keep pace with the rapidly changing technology of our times. Since 1996, the Department of Justice has consistently taken the position that the ADA applies to web content.

This checklist helps developers identify potential accessibility issues affecting their websites or applications. It’s broken down into three sections of decreasing importance: A, B and C. Please check and address these issues in the order in which they appear.

Info and Relationships> Info and Relationships # Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text. Content/Design Considerations Use simple tables instead of complex tables whenever possible Development Considerations

Many aspects of accessibility are fairly easy to understand and implement. Some accessibility solutions are more complex and take more knowledge to implement. It is most efficient and effective to incorporate accessibility from the very beginning of projects, so you don’t need go back and to re-do work.

Keyboard> Keyboard # All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, except where the underlying function requires input that depends on the path of the user’s movement and not just the endpoints.

More than one way is available to locate a web page within a set of web pages except where the web page is the result of, or a step in, a process.

Alternate versions of web pages should only be used when the main page can’t be made accessible. There are very few instances where they would be necessary. Live dynamic mapping applications are one example.

Sensory Characteristics> Sensory Characteristics # Instructions provided for understanding and operating content do not rely solely on sensory characteristics of components such as shape, size, visual location, orientation, or sound.

The complete title is Directive (EU) 2019/882 of the European Parliament and of the Council of 17 April 2019 on the accessibility requirements for products and services. Compared with other parts of the world, accessibility of Europe’s private sector (which means: companies) is not yet regulated.

Link Purpose (In Context)> Link Purpose (In Context) # The purpose of each link can be determined from the link text alone, or from the link text together with its programmatically determined link context, except where the purpose of the link would be ambiguous to users in general.
