Digital accessibility is a topic that is gaining increasing relevance in today's world.

Ensuring that everyone can use the internet, regardless of their physical, cognitive, or sensory abilities, is fundamental to inclusion and equal opportunities.

In this comprehensive guide, we'll cover everything you need to know about digital accessibility, from the basics to best practices and tools.

Let's dive into this universe and make the internet a more inclusive place for everyone!

What is Digital Accessibility?

Digital accessibility is the practice of ensuring that everyone, including people with disabilities, can access, understand, and interact with online content and services.

It involves identifying and eliminating barriers that may impede the full and independent participation of everyone, regardless of their abilities or limitations.

Therefore, digital accessibility is essential to promote social inclusion, equal opportunities, and human rights, in addition to bringing benefits to companies and organizations.

Accessibility vs. Usability

Although accessibility and usability are related concepts, they are not synonymous.

THE accessibility focuses specifically on ensuring that people with disabilities can access and use websites, apps, and other digital resources.

Already the usability refers to the ease of use and efficiency of a product or service for all users, regardless of their abilities.

A website can be accessible but not have good usability, and vice versa.

However, by combining accessibility and usability, we can create more inclusive and efficient online experiences for everyone.

Benefits for everyone

Digital accessibility benefits not only people with disabilities, but also society as a whole. Let's look at some advantages of digital accessibility:

Greater audience reach: By making online content and services accessible, businesses and organizations can reach a wider audience, including the more than one billion people worldwide who live with some form of disability.
Improved user experience: Applying accessibility guidelines often results in improved user experience for everyone, including older adults, mobile device users, and those with slow internet connections.
Compliance with legislation: In many countries, digital accessibility is a legal requirement. Ensuring compliance with laws and regulations can help avoid fines, lawsuits, and reputational damage.
Better SEO: Many digital accessibility practices, such as using alternative descriptions for images and properly structuring headings, also improve search engine optimization (SEO), making content easier to find and index.
Corporate social responsibility: Companies and organizations that commit to digital accessibility demonstrate social responsibility, which can improve public perception and increase customer loyalty.

Therefore, it is important that a company, which has the responsibility of optimizing society as a whole, is aware of these advantages and puts accessibility on its agenda.

Furthermore, the company needs to be aware of digital accessibility laws. Let's take a closer look at this.

Digital Accessibility Laws and Guidelines

To ensure digital accessibility, several countries and international organizations have developed specific laws and guidelines. These standards provide a set of recommendations and requirements to make digital environments more accessible to all users.

Web Content Accessibility Guidelines (WCAG)

WCAG is a set of international guidelines developed by the World Wide Web Consortium (W3C) to ensure the accessibility of web content.

Currently, in version 2.1, WCAG includes 78 success criteria, organized into three conformance levels (A, AA, and AAA).

These criteria address issues such as navigability, readability, and compatibility with assistive technologies. Adopting WCAG guidelines is widely considered best practice for ensuring digital accessibility.

Section 508

In the United States, Section 508 is an amendment to the Rehabilitation Act of 1973 that requires federal agencies to make their information and communication technologies (ICT) accessible to people with disabilities.

This includes websites, applications, and electronic documents.

Section 508 builds on the WCAG guidelines and establishes specific requirements to ensure that digital resources are accessible to all users, regardless of their abilities.

This amendment could become a benchmark for other countries, so it's worth keeping an eye on.

The Brazilian Inclusion Law (LBI)

Here in Brazil, we have a law that regulates issues of accessibility and inclusion.

The Brazilian Inclusion Law (Law No. 13,146/2015), also known as the Statute of Persons with Disabilities, is a comprehensive legislation that aims to promote inclusion and guarantee the rights of people with disabilities in Brazil.

The LBI includes specific provisions related to digital accessibility, requiring that websites, applications, and other digital resources be developed and adapted to ensure accessibility and usability for people with disabilities.

While the LBI does not specifically mention WCAG, adopting these guidelines is considered best practice to meet the law's requirements.

Other international laws and regulations

In addition to the laws and guidelines mentioned above, many other countries have their own legislation related to digital accessibility.

For example, in the European Union, the Web Accessibility Directive sets accessibility requirements for public sector websites and mobile applications.

In Canada, Canada's Accessible Canada Act addresses accessibility in several areas, including information and communications technology.

Therefore, it is crucial that companies and organizations are aware of the applicable laws and regulations in their respective countries and strive to ensure compliance with digital accessibility guidelines.

Principles of Digital Accessibility

Evolution in discussions related to internet accessibility has created a set of guidelines that guide companies and individuals to create accessible websites and applicationsThis became known as Accessibility Guidelines.

Accessibility guidelines, such as WCAG, are based on four core principles that help ensure digital resources are accessible to all users. These principles are:

Noticeable

Digital resources must be perceived by all users, regardless of their sensory abilities.

This means that information and user interface components should be presented in a way that can be perceived by everyone. Some practices for making content perceptible include:

Provide alternative text for images, videos, and other non-text elements, allowing users with visual impairments to understand the content through screen readers.
Provide captions and transcripts for audio and video content, facilitating access for users with hearing impairments.
Ensure adequate contrast between the text color and the background to make it easier to read for people with low vision or color blindness.

Operable

Furthermore, digital resources must be operable by all users, regardless of their motor or navigation skills.

This means that user interface components and navigation must be functional and accessible. And to make content operable, we must:

Allow keyboard navigation, ensuring that all interactive elements can be accessed and activated using only the keyboard.
Avoid using animations, interactions, or timers that could be harmful to users with epilepsy or autism spectrum disorders.
Provide clear focus cues for interactive elements, making navigation easier for users who rely on the keyboard or other assistive technologies.

Understandable

Digital resources must be understandable by all users, regardless of their cognitive or reading abilities.

Therefore, this means that the information and operation of the user interface must be clear and understandable. Practices that make content understandable include:

Use simple and direct language, avoiding jargon and technical terms whenever possible.
Organize content logically, with a clear and consistent structure, facilitating navigation and understanding.
Provide contextual help and instructions to users, explaining how to interact with interface elements or complete specific tasks.

Robust

Finally, digital resources must be robust enough to be compatible with a wide variety of assistive technologies, browsers, and devices.

In other words, content and user interface components must function reliably and consistently. To make content robust, we can:

Follow web development standards such as HTML, CSS, and JavaScript, ensuring that content is interpreted correctly by browsers and assistive technologies.
Test content across multiple browsers, devices, and assistive technologies, ensuring a consistent and error-free experience for all users.
Design and develop digital resources with a focus on scalability and flexibility, allowing them to easily adapt to future updates in assistive technologies, browsers, and devices.

By applying these four principles of digital accessibility throughout the process of creating and maintaining digital resources, you can ensure that online information, services, and opportunities are available and accessible to everyone, regardless of their abilities or limitations.

This not only promotes inclusion and equal opportunities, but can also bring additional benefits such as increased audience reach, improved user experience, and compliance with applicable laws and regulations.

Good Practices for Digital Accessibility

Now that we understand the foundation for making our digital resources and content more inclusive and accessible, let's dive into best practices on this topic.

So, here are some of the most important practices for making online content more accessible:

Proper use of headings and titles

Structure your content clearly and logically, using headings and titles to divide sections and highlight important information.

After all, this makes navigation easier for screen readers and helps all users understand the organization of the content.

For example, we've created a hierarchy of headings and text in the content you're reading. Isn't it understandable and organized?

Textual alternatives to images

Provide alt text for images, icons, and other visual elements that convey important information.

Alt text should describe the content and purpose of the visual element, allowing screen readers to provide an equivalent experience for users with visual impairments.

Therefore, pay attention to the so-called “Alt text” or Alt Text in your online content.

Attributes and descriptions for links

When creating links, use descriptive text that clearly explains the link's destination or function.

Avoid using generic phrases like “click here” or “learn more.”

Descriptive links help screen reader users understand the context and purpose of each link.

Have you ever thought about this?

Captions and transcripts for audio and video content

Provide synchronized captions for videos and other multimedia content that include dialogue or relevant audio information.

Additionally, provide audio and video transcripts that describe not only the dialogue but also important sounds and visuals.

This makes content accessible to users with hearing impairments and can also benefit people who prefer to consume content in silence or in noisy environments.

Furthermore, today social media platforms, in conjunction with artificial intelligence, already provide automatic captions for much of the content.

Colors and contrast

When choosing colors for your website or app design, consider the contrast between the text and the background.

Colors with sufficient contrast make reading easier for people with low vision, color blindness and in adverse lighting conditions.

Therefore, avoid using color as the only means of conveying information; add text or form elements to ensure that information is accessible to all users.

Keyboard navigation

This is one of the most complex best practices regarding digital accessibility.

Make sure all interactive elements of your website or application can be accessed and activated using only the keyboard.

This includes links, buttons, form fields, and other components.

Keyboard navigation is essential for users with motor impairments, as well as for those using assistive technologies such as screen readers.

Use of simple and clear language

Write content using simple, clear language, avoiding jargon, technical terms, and complex sentences whenever possible.

This way, the content is easier to understand for users with reading or comprehension difficulties, in addition to benefiting people who do not speak the language as their native language.

Adopting these digital accessibility best practices will not only ensure compliance with applicable laws and guidelines, but will also improve the overall user experience for everyone accessing your digital resources.

Therefore, by considering the needs of all users, regardless of their abilities or limitations, you will be promoting an inclusive and accessible digital environment.

Remember that digital accessibility is an ongoing process that requires regular maintenance and updates.

As technologies evolve and user needs change, it's crucial to review and update your digital resources to ensure they continue to meet accessibility standards and provide a quality experience for all users.

By applying these best practices and addressing digital accessibility comprehensively, you will be contributing to the creation of a more inclusive and equitable world, where everyone can participate and benefit from the opportunities that digital technology offers.

Additionally, by making your content more accessible, you can attract a wider audience and improve the perception and reputation of your brand or organization.
