Introduction

Web accessibilityWeb accessibility is not just a beneficial practice for those with disabilities but a proactive approach that should be integrated into web design to ensure the digital realm is accessible to all.[1]. These web accessibility guidelinesThe Web Content Accessibility Guidelines (WCAG) serve as a foundation for developers and organisations aiming to create high-quality websites and web tools, enabling individuals with a range of disabilities to navigate, understand, and interact with the Web.[2]Adhering to international web standards, including WCAG compliance, not only improves user experience for everyone but is also a legal requirement in many situations, ensuring digital inclusivity is maintained.[2] [4].

The implementation of web accessibility principles and accessible design plays a critical role in breaking down the accessibility barriers present in many current websites, effectively benefiting individuals, businesses, and society at large.[2]By encompassing all disabilities that affect access to the web, content accessibility guidelines ensure that web technologies, browsers, authoring tools, and websites work together seamlessly to support accessibility.[2]Moreover, web accessibility guidelines, including WCAG, are recognized internationally and form the basis for creating an inclusive web environment that respects the human rights of over one billion people with disabilities worldwide, fostering international participation.[4].

Understanding Web Accessibility

Understanding web accessibility involves recognizing the broad spectrum of disabilities that can affect an individual’s ability to access the web. These include:

• Auditory: Challenges in hearing audio content.
• Cognitive: Difficulties in understanding complex information and navigating web interfaces.
• Neurological: Barriers encountered by individuals with neurological disorders in interacting with digital content.
• Physical: Limitations in using a mouse, keyboard, or other input devices.
• Speech: Difficulties in using voice commands to navigate or interact with websites.
• Visual: Challenges in seeing content, including text, images, and videos [2].

To address these challenges, the Web Accessibility Initiative (WAI) has developed comprehensive strategies, standards, and resources. These include accessibility guidelines for:

1. Web Content: Ensuring text, images, and multimedia are accessible.
2. User Agents: Making browsers and media players more accommodating.
3. Authoring Tools: Assisting in the creation of accessible content [6].

Moreover, the integration of web accessibility techniques is not solely a technical challenge. It involves a commitment to ensuring that all users, regardless of the technology or assistance they utilise, can engage in enriching online experiences. This commitment includes following best practices in web design, such as optimising format, structure, navigation, visuals, and written content for accessibility. Furthermore, accessibility testing, both automated and manual, is essential in confirming a website’s accessibility standards are met.[5]Through these dedicated efforts, web accessibility not only bridges the digital divide but also addresses the economic impact of exclusion, which is estimated to cost a staggering $16.8 billion. The goal is to foster social inclusion by making the digital world accessible to everyone, thereby reducing the financial losses associated with inaccessibility.[7].

The Cornerstones of Web Accessibility

The foundational elements of web accessibility are encapsulated in the POUR principles, which guide the creation of web content that adheres to web accessibility standards, ensuring it’s accessible to all users, including those with disabilities.

• PerceivableThe ‘Perceivable’ principle underscores the necessity for information and user interface components to be presented in ways that all users can perceive, including making web content accessible and understandable.
• Providing text alternatives for non-text content [6].
• Offering alternatives for time-based media [9].
• Creating content that can be presented in different ways without losing information or structure [9].
• Enhancing the visual media experience by making it simpler for users to see and hear content, which includes effectively separating the foreground from the background to aid in perception.[9].
• Operable: User interface components and navigation must be operable. This involves:
• Ensuring all functionality is available from a keyboard [9].
• Giving users enough time to read and use content [9].
• Not designing content in a way that is known to cause seizures [9].
• Providing ways to help users navigate, find content, and determine where they are [9].
• Understandable: Information and the operation of the user interface must be understandable. This means:
• Making text readable and understandable [9].
• Making web pages appear and operate in predictable ways [9].
• Helping users avoid and correct mistakes [9].
• RobustThe ‘Robust’ principle dictates that content must be robust enough to be interpreted reliably by a broad spectrum of user agents, including those that ensure user agent accessibility, such as assistive technologies.
• It is crucial to ensure that content is robust and can be reliably interpreted by a diverse array of user agents, with a particular emphasis on compatibility with assistive technology.[9].
• Users must be able to choose the technology they use to access web content [9].

Each of these principles is pivotal for guaranteeing web accessibility, laying the groundwork for WCAG 2.2 and its defining success criteria. These core tenets are essential for creating an inclusive digital space.[9] [10].

Implementing Accessibility Features

The integration of web accessibility development into a website is a complex endeavour that demands meticulous planning and strategic implementation. To facilitate a seamless incorporation of these features, one must follow a series of deliberate steps:

1. Start Early and Evaluate Often:
• Incorporate accessibility from the project’s inception [2].
• It’s crucial to carry out accessibility audits early and consistently throughout the web development lifecycle to swiftly pinpoint and rectify any accessibility barriers.[2].
2. Basic to Comprehensive Evaluation Techniques:
• Utilise simple browser settings adjustments for preliminary evaluations [2].
• For a more in-depth analysis, it’s beneficial to engage with expert human evaluators who can ensure thorough accessibility conformance with established guidelines.[2].
3. Key Accessibility Features:
• Organising content with a clear semantic structure, utilising headings, regions, and lists, is key, and providing a skip link for direct navigation to the main content enhances usability.[15].
• Alternative Text: Provide descriptive alternative text for all non-text elements [15].
• Navigation and Forms: Ensure navigation is intuitive, with properly labelled forms and controls, and use <label> for associating labels with form controls [15].
• Aesthetics and DesignStriking a balance between visual appeal and accessibility is vital, ensuring that colour contrast and luminance contrast are optimised so that colour isn’t the only means of conveying information, and text and UI elements are easily discernible.[15] [12].
• MultimediaTo make multimedia resources fully accessible, it’s imperative to include captions, transcripts, and descriptive audio tracks for all video and audio content, catering to the needs of all users.[15].

By adhering to these guidelines, developers can craft websites that meet both website accessibility and legal standards, thereby fostering an inclusive digital environment that provides equitable web experiences for individuals with disabilities.
