Accessibility in Web Development: 21 Vital Steps to Create Inclusive WordPress & Shopify Sites

In today’s digital-first world, websites are a gateway to services, products, education, and more. But what happens when someone with a disability can’t navigate that gateway? That’s where [BKThemes](https://dev.to/ target="_blank" rel="nofollow noopener">accessibility in [web development](https://bkthemes.design/web-design-web-development-services/)** becomes essential. Whether you're building a blog on [WordPress**](https://wordpress.com), managing an online store on [Shopify**](https://shopify.com), or designing a web app, creating accessible experiences ensures that everyone* can use your site—regardless of ability.

In this comprehensive guide, you’ll learn what accessibility means, why it matters, and how to build websites that are not only user-friendly but also inclusive and legally compliant.

What is Web Accessibility?**

Definition and Importance**

[Web accessibility**](https://bkthemes.design/blog/web-development-accessibility/) means designing and developing websites so that people with disabilities can perceive, understand, navigate, and interact with them effectively. Disabilities may be visual, auditory, physical, speech-related, cognitive, or neurological.

Who Benefits from Accessible Design**
    -

    People with disabilities**

    Seniors with reduced vision or mobility**

    Mobile users in bright sunlight**

    People in noisy or quiet environments**

    Users with temporary impairments (like a broken arm)**

    Accessible websites work better for everyone, improving usability and user satisfaction across the board.

    The Legal and Ethical Side of Accessibility**

    ADA, WCAG, and Global Guidelines**

    In many countries, digital accessibility is protected by law:

      -

      ADA (Americans with Disabilities Act)** in the U.S.

      WCAG (Web Content Accessibility Guidelines)** globally recognized standard

      EN 301 549** in Europe

      Failure to comply can lead to lawsuits, especially for e-commerce and public-facing websites.

      Business Risks of Non-Compliance**

      Thousands of businesses face legal action each year for inaccessible websites. It’s not just a PR problem—it’s a real legal and financial risk.

      Accessibility as a Core Value**

      Beyond compliance, accessibility reflects your brand’s commitment to equality, inclusion, and customer care. It’s not just about doing things right—it’s about doing the right thing.

      Common Web Accessibility Barriers**

      Visual Impairments**

      This includes blindness, low vision, and color blindness. Users may rely on screen readers or magnification tools to navigate your website. Poor contrast, missing alt text, or images with embedded text create significant challenges.

      Hearing Loss and Deafness**

      For users who are deaf or hard of hearing, audio content without captions or transcripts is inaccessible. Podcasts, videos, and voiceovers must offer alternative formats.

      Motor and Cognitive Challenges**

      Users with limited motor control might use keyboards or voice commands. Complicated forms, inconsistent layouts, or flashing animations can create obstacles for those with cognitive or neurological disabilities

      Key Principles of Accessible Web Design**

      Perceivable Content**

      Ensure all users can perceive the information presented, regardless of their sensory abilities. This means using alt text, captions, and readable font sizes.

      Operable Interfaces**

      Users must be able to operate your website, whether through a mouse, keyboard, or assistive technology. That includes logical tab order and accessible navigation menus.

      Understandable Layouts**

      Content must be presented in a clear and predictable way. Headings, buttons, and form fields should all follow a logical flow.

      Robust Code**

      Your site should work well with a wide range of user agents and assistive technologies. Clean HTML, ARIA roles, and semantic structure are key.

      Accessibility in WordPress**

      Choosing Accessible Themes**

      Not all WordPress themes are created equal. Look for themes that are "[accessibility-ready](https://medium.com/@brian_27980/the-future-of-the-web-designer-with-the-advent-of-ai-7f3874d729df)"** in the WordPress directory. These are tested for compatibility with screen readers, contrast, and keyboard navigation.

      Plugins That Enhance Accessibility**

      Top accessibility plugins for WordPress include:

        -

        WP Accessibility**

        Accessibility Checker**

        One Click Accessibility**

        These help fix contrast, skip links, alt tags, and more.

        Keyboard Navigation and ARIA Roles**

        Ensure all elements can be reached via keyboard. Use ARIA (Accessible Rich Internet Applications) roles to describe dynamic content and live regions.

        Accessibility in Shopify**

        Limitations and Opportunities**

        Shopify themes vary widely in accessibility. Some are optimized, others aren’t. Start with a well-reviewed theme and check documentation for accessibility notes.

        Using Alt Text and Semantic HTML**

        Every product image should have descriptive alt text**. Use semantic HTML for headings, paragraphs, and lists to make the content understandable to screen readers.

        Shopify App Integrations**

        Apps like Accessibility Enabler** and Accessibly** provide toolbars, font resizing, contrast toggles, and more. These are especially useful for stores with limited coding ability.

        Acessibility vs Usability: What’s the Difference?**

        How They Work Together**
          -

          Usability** is about how easy something is to use.

          Accessibility** ensures it's usable by people with disabilities.

          Both aim to improve user experience, and a site that is both accessible and usable reaches the broadest possible audience.

          Improving Both Simultaneously**

          Clear layouts, readable fonts, responsive design, and logical navigation all support both accessibility and usability—no trade-off needed.

          Designing for Screen Readers**

          Use of Proper HTML Tags**

          HTML5 elements (like <header>, <nav>, <article>) provide structure and meaning. Avoid excessive <div> and <span> usage.

          Skip Navigation Links**

          Allow screen reader users to bypass repetitive navigation and go straight to content with a skip to content** link at the top of each page.

          Labeling Forms and Buttons**

          Every input field and button must have a label that screen readers can interpret. Use aria-label, aria-labelledby, or visible <label> tags.

          Color and Contrast Best Practices**

          Accessible Color Palettes**

          Avoid using color alone to convey meaning (e.g., red for error). Combine with icons, text, or underlines.

          Tools to Check Contrast Ratios**

          Use tools like:

            -

            WebAIM Contrast Checker**

            Color Oracle**

            Accessible Colors**

            Aim for a minimum contrast ratio of 4.5:1** for normal text and 3:1 for large text.

            Font Size, Readability, and Typography**

            Minimum Font Guidelines**

            Your body text should be no smaller than 16px** for readability. Smaller text can strain the eyes, especially for older users or those with visual impairments.

            Line Height and Spacing**

            Use a line height of at least 1.5** times the font size. Also, ensure there’s enough spacing between paragraphs and list items to prevent cluttered text blocks.

            Avoiding Fancy Fonts**

            Stick to clear, sans-serif fonts like Arial, Verdana, or Open Sans. Avoid decorative fonts, which may look nice but can be hard to read or confusing for screen readers.

            Image and Media Accessibility**

            Writing Effective Alt Text**

            Alt text describes the content of an image for users who can’t see it. Keep it:

              -

              Brief**

              Descriptive**

              Context-aware**

              Example:
              ❌ “Image”
              ✅ “Woman using a wheelchair entering a library”

              Captioning Videos and Audio Descriptions**

              Always provide:

                -

                Closed captions** for spoken content

                Transcripts** for podcasts

                Audio descriptions** for visual elements that are important to understanding the media

                Creating Accessible Forms and Buttons**

                Clear Labels and Placeholders**

                Don’t rely on placeholder text alone. Every input field should have a visible and programmatically labeled description.

                Error Handling and Feedback**

                Use simple, clear language for error messages, and guide users on how to correct mistakes. Red text alone is not enough—add icons or text cues.

                Touch Target Sizing**

                Buttons and links should be at least 44x44 pixels** to be easily tapped on mobile or touch devices.

                Mobile Accessibility Considerations**

                Responsive Design**

                Your site must adjust gracefully across screen sizes. Use relative units like em**, rem**, and percentages instead of fixed pixels.

                Mobile Screen Reader Support**

                Ensure headings, landmarks, and forms are logically structured so screen readers like VoiceOver (iOS) and TalkBack (Android) can interpret the layout correctly.

                Testing for Accessibility**

                Manual Testing with Assistive Tech**

                Try navigating your website using:

                  -

                  Keyboard only**

                  Screen readers** (e.g., NVDA, JAWS, VoiceOver)

                  It’s a great way to uncover real usability issues.

                  Automated Tools (WAVE, Axe, Lighthouse)**

                  These tools scan your site for accessibility violations and offer suggestions for improvement.

                  User Feedback and Accessibility Audits**

                  Real user testing, especially with people who rely on assistive tech, can reveal critical issues that automation can’t detect.

                  Accessibility Plugins and Tools**

                  WordPress Accessibility Helper (WAH)**

                  Adds accessibility settings such as font resizing, contrast toggle, alt tag audits, and skip links.

                  Shopify Accessibility Tools**

                  Apps like Accessibility Enabler**, Accessibly**, and EqualWeb** offer plug-and-play accessibility enhancements for Shopify stores.

                  Browser Extensions**

                  Try:

                    -

                    WAVE (WebAIM)**

                    axe DevTools**

                    Color Contrast Analyzer**

                    These help check compliance while browsing or developing.

                    Maintaining Accessibility Long-Term**

                    Content Updates**

                    Even if your site was **[fully accessible at launch](https://bkthemes.design/wordpress-design-trends-using-elementor-2025/)**, adding new images, products, or blog posts may reintroduce accessibility issues. Regular updates matter.

                    Training Your Team**

                    Teach your content writers, designers, and developers how to keep accessibility in mind during day-to-day updates.

                    Setting an Accessibility Policy**

                    Outline your commitment, procedures, and responsibilities. This keeps your whole organization aligned on inclusive practices.

                    Accessibility and [SEO](https://bkthemes.design/seo): A Hidden Connection**

                    How Accessibility Boosts Rankings**

                    Search engines reward:

                      -

                      Proper heading structure

                      Clear link descriptions

                      Mobile-friendly design

                      These are also accessibility best practices.

                      Shared Benefits for All Users**

                      Improved speed, usability, and navigation help everyone—especially people with slow internet, outdated devices, or limited tech skills.

                      Accessibility in [web development](https://bkthemes.design/web-design-web-development-services/) for E-Commerce**

                      Accessible Checkout Flows**

                      A poorly designed checkout process can be a deal-breaker. Make sure:

                        -

                        Every field is clearly labeled.

                        Errors are easy to fix.

                        The entire process works with a keyboard or screen reader.

                        This is especially important for Shopify** and WordPress WooCommerce** stores.

                        Navigable Product Listings**

                        Users should be able to navigate product categories, filters, and items without confusion. Use consistent headings, descriptive links, and ARIA labels for dropdowns or dynamic elements.

                        Inclusive Promotions and Popups**

                        Avoid popups that are hard to dismiss or block the main content. Always ensure promotions are keyboard-friendly and don’t trap users on the page.

                        Cost and ROI of Investing in Accessibility**

                        Development Costs**

                        Yes, building accessible websites may have upfront costs. But integrating accessibility from the start is far more affordable than retrofitting later or facing legal challenges.

                        Benefits: More Visitors, Better UX**

                        Accessible websites have:

                          -

                          Lower bounce rates**

                          Higher engagement**

                          More return visitors**

                          You open your site to a wider audience, including over 1 billion people** globally who live with some form of disability.

                          Case Studies of Accessible Brands**
                            -

                            Apple**: Market leader in inclusive tech.

                            BBC**: Global leader in screen reader navigation and media captions.

                            Target**: Invested in accessibility after a lawsuit and now serves millions better.

                            FAQs About Accessibility in [web development](https://bkthemes.design/web-design-web-development-services/)**

                            What is WCAG and why does it matter?**

                            WCAG (Web Content Accessibility Guidelines)** is a set of international standards for web accessibility. It outlines how to make websites usable for everyone, especially those with disabilities.

                            Is WordPress fully accessible out of the box?**

                            Not entirely. While WordPress core is built with accessibility in mind, some themes and plugins may not be compliant. Choose “accessibility-ready” themes and test your plugins.

                            What tools can I use to test my site?**

                            Start with:

                              -

                              WAVE (WebAIM)**

                              Axe DevTools**

                              Google Lighthouse**

                              Screen readers** like NVDA or VoiceOver

                              Can accessibility improve conversion rates?**

                              Yes! Easier navigation, readable content, and a smoother experience benefit all users—not just those with disabilities.

                              How often should I audit my site for accessibility?**

                              At least every 6–12 months**, or whenever you launch a new design or major feature.

                              Does Shopify support full accessibility?**

                              Shopify has made improvements, but full accessibility depends on the theme** and apps** you use. Choose themes built with accessibility in mind and test your store thoroughly.

                              Conclusion: Accessibility Is Everyone’s Responsibility**

                              Inclusive Design Is Smart Design**

                              Accessibility in [web development](https://bkthemes.design/web-design-web-development-services/) isn't just a technical requirement—it's a human one. Every element, from buttons and menus to videos and checkout pages, should welcome everyone*, regardless of ability.

                              Whether you're a solo entrepreneur on Shopify**, a developer building custom apps, or a blogger using WordPress**, accessibility means treating your users with respect and empathy.

                              Your Next Steps Toward a More Accessible Web**
                                -

                                Audit your current site with tools and real user feedback.

                                Choose accessible themes and plugins.

                                Prioritize clear structure, readable text, and alternative formats.

                                Keep learning and stay updated on WCAG standards.

                                By making your site more accessible, you build a better internet—one that values inclusivity, equality, and excellent user experience.
