Web Accessibility Guide for Inclusive Digital Design
The Basics of Web Accessibility
Web accessibility ensures that digital platforms are inclusive and usable for everyone, regardless of physical or cognitive impairments. It’s about removing barriers so that all individuals can interact with websites, applications, and digital tools. Beyond disabilities, accessibility also takes into account temporary challenges like a broken arm or situational conditions such as glare from sunlight on a screen.
This guide explores the essentials of web accessibility, including the core principles, common features, testing methods, and valuable resources. We’ll also share our reflections on how accessibility aligns with our own agency's values.
What is Web Accessibility?
Web accessibility is the practice of designing and developing websites to ensure they are accessible to all users, irrespective of any limitations. Simply put, it removes obstacles that might hinder people from interacting with or gaining meaningful access to digital platforms.
Accessibility isn't solely about people with permanent disabilities; it’s also about accommodating diverse circumstances. For example:
- A person with a broken arm may rely on keyboard navigation.
- Bright sunlight might make a low-contrast app challenging to read.
- Older adults may require simpler interfaces or resizable text for better visibility.
Accessibility is about inclusivity for all, regardless of the situation.

The Four Principles of Accessibility (POUR)
Accessibility revolves around four foundational principles, collectively known as POUR—Perceivable, Operable, Understandable, and Robust. These principles guide developers in creating websites and apps that work for everyone.
1. Perceivable
Information presented must be accessible to all users, regardless of sensory limitations.
- Providing alt text for images.
- Using readable fonts and strong contrast between text and background.
- Adding captions and transcripts to video/audio content.
2. Operable
Users should be able to interact with and navigate digital content easily.
- Designing keyboard-navigable menus.
- Including adjustable time limits for completing tasks.
- Adding "skip links" to bypass repetitive sections of a page.
3. Understandable
Your content and interface should be easy to understand and predictable.
- Using consistent navigation patterns.
- Providing clear error messages with instructions on how to fix mistakes.
- Ensuring forms have labeled fields for guidance.
4. Robust
Digital content must function seamlessly across different devices and assistive tools.
- Following coding standards for compatibility with screen readers.
- Testing websites on multiple browsers and devices.
- Using progressive enhancement strategies to ensure usability across outdated or cutting-edge technologies.
Why Accessibility Matters to Developers
Accessibility isn’t just a moral obligation; it’s a marker of quality and foresight in digital development. Here’s why accessibility should be a priority for any developer or agency:
- Technical Excellence: Implementing accessibility often aligns with best practices in web development, such as using semantic HTML. This enhances both usability and functionality.
- Reaching a Broader Audience: Accessible websites include everyone, from people with disabilities to those facing temporary or situational challenges. This inclusivity drives engagement and increases your audience reach.
- Future-Proofing Your Platform: Accessibility is becoming a core requirement as web standards evolve. Building with accessibility in mind saves you from costly upgrades or compliance retrofits in the future.
- Meeting Legal Requirements: Many regions have enacted laws mandating accessible digital platforms. Non-compliance can result in litigation and reputational damage.
Accessibility supports ethical values while enhancing your platform’s performance and sustainability.
Common Accessibility Features
Making your platform more accessible doesn’t need to be overwhelming. Start by implementing these impactful features for a more inclusive user experience:
- Alternative Text (Alt Text): Descriptions for images, enabling screen readers to convey visual content.
- Keyboard Navigation: Ensure interface elements can be operated without a mouse.
- ARIA Landmarks: Helpful labels that enable assistive devices to identify web content.
- Readable Fonts and Contrast: Maintain readability by ensuring sufficient text-to-background contrast.
- Captions and Transcripts: Provide captions for videos and transcripts for audio files.
- Resizable Text: Allow users to adjust text sizes without breaking layouts.
- Skip Links: Add shortcuts to skip repetitive content like navigation menus.
- Error Guidance: Highlight form errors clearly and provide solutions for resolving them.
- Descriptive Titles and Headers: Help users and screen readers understand page content effortlessly.
- Accessible Forms: Use clear labels, error messages, and logical field groupings.
Accessibility Testing
Accessibility testing is a critical step in creating inclusive platforms. Here’s how to ensure your digital tools meet accessibility standards:
1. Automated Testing Tools
Tools like WAVE, axe, and Lighthouse help identify common accessibility issues. While helpful, they should supplement—not replace—manual evaluation.
2. Manual Testing
Manually review your site while simulating different user experiences. Use screen readers, try keyboard-only navigation, and test across devices.
3. User Testing
Invite people with diverse disabilities to test your platform. Their feedback is invaluable for understanding potential gaps in accessibility.
4. Code Validation
Run your code through validators like the W3C Markup Validation Service to ensure compliance with web standards.
5. Ongoing Updates
Accessibility isn’t a one-off task. Conduct regular checks during maintenance cycles to ensure ongoing compliance.
Document the methods, tools, and results of your tests to refine strategies and demonstrate your commitment to accessibility.
Why Accessibility Matters to Us
Web accessibility is deeply personal to us. Our commitment started years ago when we partnered with a non-profit serving individuals with disabilities. That project opened our eyes to how technology can bridge gaps—or widen them if inclusivity is overlooked.
We believe accessibility should be a guiding principle, not an afterthought. Creating web platforms that anyone can use reflects the values of fairness, inclusivity, and respect.
