The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect. Tim Berners-Lee, W3C Director and inventor of the World Wide Web

What Web Accessibility Standards are in a Nutshell

Currently, the web usability definition reads as follows: the inclusive practice of ensuring there are no barriers that prevent interaction with, or access to, websites on the World Wide Web by people with physical disabilities, situational disabilities, and socio-economic restrictions on bandwidth and speed.

For catering to all categories of users with equal opportunities for web browsing, the World Wide Web Consortium (W3C), represents Web Content Accessibility Guidelines (WCAG), which contain clear instructions on how to make a website browsable and provide website accessibility for disables users. The first version was released in 1999, then WCAG 2.0 in 2008. Since 2018, the most current version is WCAG 2.1. Web Consortium also announced the release of WCAG 3.0 in late 2022.

Why It’s Important to Follow Web Accessibility Guidelines

Currently, there are two main reasons that make business owners search for the answer to the question “how to make a website more accessible for the disabled”. The first one is the desire for providing equal opportunities for browsing for all the categories of users, whatever limitation they may have.

The second factor inspiring business owners in making digital content accessible is a legal one. So, why is accessibility important from a legal standpoint? Depending on jurisdiction, the reality is that many websites put themselves at risk to be sued for not providing their users with an accessible interface.

The legal world can already illustrate such examples as the case of Domino’s – the multinational pizza restaurant chain that prides itself on providing an exceptional customer experience. In October 2016, legally blind man Guillermo Robles, filed a lawsuit claiming that Domino’s website was not accessible via screen reader, and he was unable to order a pizza this way.

Guillermo Robles won the trial at the 9th Circuit Court of Appeals. The US Supreme Court then declined to hear a further appeal after the pizza magnate sought to have the decision overturned. The court essentially held that from this point forward, websites should be treated as places of public accommodation, and thus they should provide equal opportunities for browsing to all categories of users with diverse abilities. This decision essentially opens the door for more lawsuits and higher expectations for mobile and website accessibility. And now, Domino’s can say a lot on how to make a website blind-accessible on the basis of their own experience.

Levels of Website Accessibility Guidelines

The answer to the question “how do I make my website accessible?” should start from learning the basics of the website accessibility guidelines. Actual web accessibility guidelines consist of three levels of web content accessibility:

  • Level A – which includes the most basic rules
  • Level AA – the essential one in light of the ruling above
  • AAA level – provides the widest opportunities for access to content

Web Content Accessibility Guidelines

Each of the WCAG compliance levels consists of three components that work together. These components are:

  • Web Content Accessibility Guidelines (WCAG). WCAG refer to any part of a website, including text, images, forms, and multimedia, as well as any markup code, scripts, applications, and so on.
  • User Agents Accessibility Guidelines (UAAG). UAAG are about the software that’s used by people to access web content. This software can be desktop graphical browsers, voice browsers, mobile phone browsers, multimedia players, plug-ins, and some assistive technologies.
  • Authoring Tools Accessibility Guidelines (ATAG). This component of accessibility refers to the software or services that enable people to produce web content, including code editors, document conversion tools, content management systems, blogs, database scripts, and other tools.

In this article, we focus on considering Web Content Accessibility Guidelines. WCAG accessibility relies on four main principles of information provided, that are abbreviated as POUR – Perceivable, Operable, Understandable and Robust. Keep reading and discover the actual WCAG 2.1 checklist below!

Perceivable information and user interface

The first component of web accessibility guidelines is the perceivability principle. So, let’s look at how to make your website more accessible in terms of the perceivability principle. First and foremost you must ensure that both the information and user interface components are presented to users in ways they can perceive. This means that any user must be able to receive and process the information being presented with at least one of the senses. Currently there are two main approaches to gain perceivability – text alternatives and captions usage.

ADA website compliance guidelines: Perceivable

Text alternatives for non-text content

Text is a real savior when it comes to representing non-text content. Below are examples of how you can use text to represent non-text information:

  • Use short equivalents for images, including icons, buttons, and graphics.
  • Implement descriptions of data represented on charts, diagrams, and illustrations.
  • Utilize brief descriptions of audio and video files.
  • Employ labels for form controls, input fields, and other user interface components.

Captions and other alternatives for multimedia

People who are hearing or visually impaired can’t hear audio or see video. Consequently, they need some alternatives to receive the information. Such alternatives can be the following:

  • Exploit text transcripts and captions for audio content like radio interview recordings.
  • Handle audio descriptions to reference important visual details in a video.
  • Implement sign language interpretation of audio content.

You should also take into account that well-written text transcripts containing the correct sequence of any auditory or visual information will provide a basic level of accessibility and facilitate the production of captions and audio descriptions.

Operable user interface and navigation

The operability aspect states that user interface components and navigation must be operable. Put simply, users must be able to operate the interface and the interface cannot require interaction that a user cannot perform.

Being operable for content means providing such components as keyboard accessibility, sufficient time, navigation, and input modalities.

Website accessibility guidelines: Operable

Keyboard accessibility

Some people do not use a mouse. Instead, they rely on the keyboard to interact with the web. This approach requires fully-fledged keyboard access to all functionality, including form controls, input, and other user interface components.

Keyboard accessibility requirements include:

  • Making all functionality available by the keyboard.
  • Ensuring the keyboard’s focus does not get trapped in any part of the content.

Sufficient time

Some categories of people need more time than others to read the content and interact with it. For instance, such actions as typing text, understanding instructions, operating control elements or completing tasks on a website may be time-consuming.

To provide the users with sufficient time for fully-fledged interaction with your website, we recommend that you consider the following measures:

  • Make it possible to stop, extend, or adjust time limits, except when necessary.
  • Implement features to pause, stop, or hide moving, blinking, or scrolling content.
  • Enable re-authentication without any data-loss when a session expires.


Ensuring web content is well-organized is an important step since it guides users through the website and helps them to orient themselves and navigate effectively. The following steps will help you make your website navigable to ita users:

  • Write clear meta-title tags for all the pages across the website
  • Provide an opportunity to reach every webpage in multiple ways
  • Implement breadcrumbs to inform users with actual information about their current location
  • Make it possible to bypass blocks of content that are repeated across multiple pages
  • Ensure the keyboard focus is visible, and the focus order follows a meaningful sequence
  • All the links should have clear and evident purpose

Input modalities

One more idea you can consult to answer the question of how to make your website accessible is addressing input modalities. The introduction of input modalities beyond the keyboard is vital when it comes to providing web content accessibility. Such input modalities can be represented as touch activation, voice recognition (or speech input), and gestures. Yet, not everyone can use each of these input modalities, nor to the same degree. Particular design considerations can maximize the benefit of these input modalities and increase accessibility compliance for the websites. Here are few examples:

  • Gestures that require dexterity or fine movement should have alternatives that do not require high dexterity.
  • You must design major components in a way to avoid accidental activation, for example by providing an undo functionality.
  • Providing users with labels that match corresponding object names in the code to support activation by voice.
  • Implementing functionality in a way that users can activate it by movement or through user interface components.
  • Designing buttons, links, and other active components large enough to make them easier to be activated by touch.

Understandable information and user interface

Being understable for website content means that any user must be able to understand all the information provided along with the user interface. So, what makes a website accessible in terms of understandability? The main ways for obtaining understandable website content are following the principles of readability, predictability and input assistance.

ADA WCAG: Understandable


When working on creating accessible websites, content writers must ensure that every piece of the text content is readable and understandable enough to the broadest audience possible, as is implemented in the best e-commerce blogs. Cases when the text content is read aloud by text-to-speech should also be taken into account. You can reach it by the following ways:

  • Identifying the primary language of a web page, as well as identifying the language of separate text passages, phrases, or other parts of a web page.
  • Providing definitions for any unusual words in the text content, as well as for phrases, idioms, abbreviations, and so on.
  • Using clear and simple language, or providing simplified versions of the text content.


Many people get disoriented or distracted by the inconsistent appearance or behavior of web content. To prevent this, you must follow the principle of predictability, which states the following:

  • When you place the navigation panel on multiple pages, place it in the same spot each time
  • User interface components that are repeated across the pages on the website should have the same labels
  • No changes on the web page happen without the consent of the user

Input assistance

Some interactions on the website can be particularly confusing to users. One such monster for people can be simply filling out inputs – many people claim they experience difficulties with it, and that results in them inadvertently making mistakes. Here are the ways you can help your users prevent, avoid, or correct such mistakes:

  • Add descriptive instructions, error messages, and suggestions for correction.
  • Implement context-sensitive help for more complex functionality and interaction.
  • Provide an opportunity to review, correct, or reverse submissions if necessary.


The fourth and the last principle of WCAG guidelines is robustness. According to this principle of accessibility requirements for the websites, you should strive for making content robust enough so that it can be interpreted properly by a wide range of user agents, including assistive technologies. One more requirement here is that users must be able to access the content along with the development of technologies, which means the content must remain accessible in concert with evolving technologies and user agents.

ADA compliance standards for websites: Robust


The only component for the robust principle is compatibility, which states that content should be compatible with different browsers and assistive technologies, as well as with other user agents. This can be achieved via the following measures:

  • Making sure the markup can be reliably interpreted by simply verifying it’s valid.
  • Providing a clear explanation of name, role, and value for non-standard user interface components.

Web Accessibility Evaluation: Tools, Methods, and Techniques

To ensure that everything is fine with your website in terms of accessibility, the best option is implementing one of the widely-available tools that can assist here. The best of them can help you with testing your website, as well as delivering clear and understandable recommendations not just on how to make a website accessible for the disabled, but how to do so and make it even better than ever for abled users, too.

Currently, you can find plenty of tools and automatic checkers to verify the accessibility of your website. Among the most popular of them, we distinguish the following:

1. WAVE by WebAIM

The most popular accessibility checker to date, WAVE is available both online and as a Firefox add-on. Developed by WebAIM, an organization devoted to making web content accessible to people with disabilities, WAVE gives clear recommendations about how to enhance particular page’s accessibility and provides a comprehensive understanding of how to make your website ADA compliant.

2. AChecker

AChecker (or Accessibility Checker), is an open-source tool to help you obtain a clear impression about your website accessibility. Developed by the Inclusive Design Research Centre (formerly known as the Adaptive Technology Resource Centre) of the University of Toronto in 2005, this tool remains one of the most popular when it comes to answering the question of how to make your website handicap accessible.

Whidegroup’s Expertise in Creating ADA-Compliant User Experience

Let’s learn how you can improve the accessibility of your design and the website in general by considering real examples. Recently, one of our clients decided to provide web accessibility options for browsing his website. To make this come true, we used Equalweb software, which provides 100% compliance with WCAG 2.1 – the latest web content accessibility guidelines available. The process of making the website available looked as follows:

  • We inserted JavaScript code provided by Equalweb into the website source code.
  • Then our developers reviewed the website manually to examine whether everything went right and made some minor fixes.
  • QA engineers did final testings for ADA compliance and verified that the website is accessible.

As for the timeframes of the process – in general, we spent around 40 minutes for each page to implement accessibility features on the website.

ADA-compliant website development: our experience

The final result after applying accessibility requirements for websites on the part of the user looks as follows: after accessing the website, visitors can see the disability icon with a caption inviting them to open the accessibility options menu. The menu itself is opened as a sidebar and represents features intended to make the website accessible. The features are represented as clear icons, which are also supplemented with text captions. The users can:

  • Change the contrast
  • Change the cursor
  • Use a magnifier lens
  • Change the font size
  • Highlight the links and many more

Due to visually impaired website compliance, visitors can use text readers, voicing all the text content on the page.
