Web accessibility ensures websites and online content are user-friendly for everyone, including individuals with disabilities. Think of it as constructing a building with ramps and elevators to enable people of all physical abilities to navigate effortlessly. It means using plain and understandable text, offering image alternatives, and structuring content logically online. These guidelines guarantee that all users can easily access and comprehend online information, regardless of their capabilities. Web accessibility aims to establish an inclusive online environment where everyone can engage and reap the benefits of the digital realm.

What is Web Accessibility?

Web accessibility ensures that websites are user-friendly for everyone, including individuals with disabilities or limitations. Achieving this requires designing sites that provide a comparable experience to all users, irrespective of their unique challenges. This approach guarantees that all individuals can readily access and utilize the website’s content without encountering difficulties. In essence, web accessibility aims to ensure that every person, regardless of their abilities or limitations, can comfortably navigate and interact with a website.

Web Accessibility Standards

The latest version of WCAG outlines four primary principles for crafting an accessible website. These principles encompass a set of web accessibility guidelines that you can consult and strive to implement whenever and wherever feasible on your website.


Accessibility is a multifaceted concept encompassing various aspects, from legal frameworks to precise technical guidelines. Within web content accessibility, there are four fundamental principles known as POUR: Perceivable, Operable, Understandable, and Robust. These principles serve as the industry’s standard framework for ensuring that digital content is accessible to all. To provide a foundational understanding of accessibility, we’ve created an introductory guide to these principles. In simpler terms, it’s a way to make digital content, like websites, easy for everyone to use and understand, following these four fundamental principles for a more inclusive online experience.


In web accessibility, ‘perceivable’ means that website content should be easily noticeable and understandable by all users, including those with disabilities like blindness or low vision. To illustrate, people who are blind often rely on screen reader software that reads content aloud or converts it into braille. Achieving permeability on your website involves providing descriptive image text, using clear language, and adding video captions. Ultimately, the aim is to guarantee that your website’s content is accessible to everyone, regardless of their abilities.”


Operable websites provide a hassle-free experience for visitors, ensuring that everyone can effortlessly utilize all their features. It includes browsing pages, selecting menu options, and controlling video and audio playback. Effective operable websites often favor simplicity by eliminating extra functions that could pose difficulties for users with disabilities or limitations. Operability means that a website runs smoothly and effectively for all, avoiding any hindrances or complexities. The core aim is to establish an online environment that’s accessible and user-friendly for individuals of varying abilities and circumstances.


While users must perceive and operate a website, they must still understand it fully. Websites must also prioritize being understandable. It means using clear and concise language and offering user-friendly features. Users should easily connect their actions with the expected outcomes. Consistent navigation is vital to ensuring users can always find their way around. Forms should follow a logical sequence with clear labels. For processes like checkout, clear guidance is essential. The link between usability and accessibility is strong because user-friendly websites naturally tend to be more accessible. It fosters an online environment that welcomes everyone with open arms.


In web accessibility, “robust” denotes the strength and resilience of a website’s design and underlying code. A robust website possesses the capacity to endure various challenges and adapt to evolving technology, ensuring its continued functionality and accessibility. To simplify, consider a powerful website as a sturdy and versatile structure capable of withstanding different environmental conditions. In the digital sphere, this implies that the website’s design and code handle diverse web browsers, devices, and assistive technologies people use to access the internet. This approach safeguards the website’s functionality and accessibility, even as technology advances.

How to Make Your Website Accessible

Upon reflection on the abovementioned principles, you may recognize that your website only partially adheres to these standards. Alternatively, if you’ve utilized an accessibility testing tool and received a less-than-satisfactory rating, you’re not alone in this predicament. In both scenarios, the WCAG offers comprehensive guidelines for each of the four principles we’ve discussed. These guidelines present concrete steps you can readily implement to improve your website’s accessibility. For those seeking a thorough review of these guidelines, our extensive web accessibility checklist can offer further assistance and direction.

By following these guidelines, websites become operable, allowing all users to engage with the content and functionality effectively, promoting inclusivity and usability.

Understandable Web Accessibility Guidelines

Understandable Web Accessibility Guidelines focus on making digital content easy to comprehend for all users. It means using clear and straightforward language, avoiding jargon, and ensuring that the relationship between actions and outcomes is apparent.

By adhering to these guidelines, websites become more understandable, ensuring that all visitors, including those with cognitive challenges or language differences, can access and comprehend the content and features, promoting a more inclusive and user-friendly online environment.

Robust Web Accessibility Guidelines

Robust Web Accessibility Guidelines focus on making digital content and technology resilient and adaptable. It means ensuring that websites and applications work reliably across various devices, browsers, and assistive technologies. Following these guidelines, web developers and designers ensure that their digital creations remain functional and accessible as technology evolves. This adaptability ensures that people can continue to use and interact with the content, regardless of the tools or devices they employ. In essence, robust accessibility guidelines future-proof digital experiences, making them durable and accessible to many users.
