Web Accessibility- A Comprehensive Guide

Web accessibility is an essential part of any development project because a common end goal for every product is to be accessible to every user including those who have broken arms. The benefit of this feature is not just focused on the disability spectrum, it should also strive to help all sections of society including people in their old age, people with temporary incapacities, and situational restrictions. 

An organization must adhere to a long-term, sustainable strategy with no deadline if it wants to succeed in increasing accessibility. The organization’s standard practices must include accessibility. Similar to how all designs should take security, optimization for search engines, and privacy into account, all designs must include accessibility.

There are several key principles of web accessibility:

Perceivable: Web content and functionality must be presented in a way that users can perceive it. This includes providing alternatives for non-text content, such as images and videos, and ensuring that text can be resized and color contrast is sufficient.

Operable: Web content and functionality must be operable by users. This includes providing keyboard-accessible alternatives for mouse-based interactions and ensuring that users can pause, stop, or hide moving or scrolling content.

Understandable: Web content and functionality must be easy for users to understand. This includes using clear and simple language and providing context and instructions when necessary.

Robust: Web content and functionality must be robust enough to be used with a variety of assistive technologies. This includes using semantic HTML tags and following web standards.

Web Accessibility Standards

There are several tools and resources available to help developers create accessible websites and web applications. These include the Web Content Accessibility Guidelines (WCAG), which provide a set of standards and guidelines for making web content more accessible. It also includes the WAVE tool, which allows developers to check the accessibility of their websites.

In addition to benefiting individuals with disabilities, web accessibility has broader benefits. For example, it can improve the user experience for everyone, including older users. It can also help businesses and organizations reach a wider audience and comply with legal requirements.

To ensure that your website or web application is accessible to all users, it’s important to incorporate web accessibility best practices into your development process from the beginning. It includes testing your site with assistive technologies, conducting user testing with individuals with disabilities, and regularly reviewing and updating your site. This ensures that it meets the latest web accessibility standards.

Features of Accessibility

There are several features in web accessibility that help to improve the user experience on a website.  This includes features like text-to-speech, keyboard shortcuts, etc. Many of these features are already inbuilt into the user’s system. 

Some of such features are: 

  • Instead of reading what’s on the screen, users can hear it. Thanks to features like text-to-speech. Other features like high-contrast themes and bigger cursors make it simpler for the users with poor eyesight to view the screen.
  • Closed captioning enables the visual presentation of audio information for hearing-impaired users. Mono audio systems transmit both the right and left audio signals through earbuds and headphones, ensuring that listeners who have hearing loss in one ear do not miss any of what they are hearing.
  • Many individuals find keyboard shortcuts convenient, but those who have trouble physically using a mouse benefit most from them. Sticky keys enable users who have trouble pressing multiple keys at once to activate a shortcut by pressing a single key.

Web Accessibility Evaluation

Evaluation of web accessibility is a vast field that involves several disciplines and abilities. It includes both technical and non-technical elements. This includes the participation of end users in the evaluation process, as well as technical elements like the evaluation of adherence to standards and guidelines. Web accessibility is a qualitative and experience metric as opposed to a quantitative and concrete attribute. Hence evaluation approaches must use a variety of strategies while being adaptable to various circumstances. However, in order to be successful, evaluation systems must be solid and trustworthy.

Accessibility Tools

Accessibility tools, whether automated ones like axe DevTools and axe Monitor or even manual ones like axe Auditor, can be of great use. Yes, you should use them without a doubt, but they won’t finish the task for you.

Automated tools make it quicker to uncover many different accessibility problems. They also provide accurate measurements of standard compliance, but they can’t find everything. About 57% of accessibility may now be found using axe rules. As the tools advance, this percentage will rise, but they can never achieve 100% with automated testing alone. Certain accessibility difficulties will always call for human discretion.

Someone needs to intelligently address the issues that the tools find, even with the fraction of concerns that automated techniques can identify. Even if automated technologies can produce a list of accessibility problems, the list is meaningless if no one has the knowledge or know-how to fix the problems properly.

Some accessibility problems are simple to comprehend and resolve. Others call for a deeper understanding of accessibility. Incorrect solutions run the danger of failing to address the root of the issue and even leading to the development of new ones.

Additionally, it’s important to note that automated technologies only test content, not design concepts. It’s also crucial to remember that general design decisions, rather than individual lines of code or components of an application, have the greatest influence on users. Since teams should, ideally, make sound design judgments first, automated tools are essentially a second line of defense.


This manual was created to equip web designers with the awareness and expertise necessary to create accessible websites and web content. It is for both who are employed by a company or work as independent consultants.

However, everybody benefits from web accessibility. The inclusion of accessibility into the layout and performance of websites will help companies and clients of all abilities as the population ages, technology develops, and online commerce rises. As a result, businesses and web designers must constantly think about the users of their websites and the technologies they employ to access them.
