Getting Started with

Accessibility

Web accessibility helps people with disabilities use websites, applications, documents, forms, checkout flows, videos, navigation, and online services. Practical accessibility work often focuses on WCAG, the Web Content Accessibility Guidelines, and ADA, the Americans with Disabilities Act. The goal is to remove barriers that prevent people from reading content, using a keyboard, understanding forms, completing purchases, watching media, accessing documents, or interacting with online services.

Make sites usable

Accessibility improves real usability for people using screen readers, keyboards, magnification, captions, voice control, alternative input devices, or other assistive technologies.

Reduce compliance risk

WCAG-aware implementation and ADA-aware review help organizations identify barriers, prioritize fixes, document good-faith progress, and reduce avoidable exposure.

Improve quality

Accessible markup, clear forms, keyboard support, readable contrast, captions, predictable navigation, and semantic structure often improve the experience for all users.

WCAG and ADA in practical terms

WCAG provides technical guidance for making web content more accessible. It is commonly used as the benchmark for evaluating websites, applications, documents, and digital interfaces. WCAG success criteria are organized around four principles: content should be perceivable, operable, understandable, and robust.

ADA is a civil rights law that addresses discrimination against people with disabilities. For websites and applications, ADA-related accessibility questions often involve whether people with disabilities can effectively access the goods, services, programs, activities, or information offered online.

Practical note: Accessibility work is both technical and legal-adjacent. We can help identify and remediate technical barriers, but legal obligations, settlement risk, formal compliance positions, and policy language should be reviewed with qualified legal counsel when needed.

WCAG introduces technical guidance

  • Can users perceive the information?
  • Can users operate the interface without a mouse?
  • Are instructions, labels, errors, and navigation understandable?
  • Does the code work reliably with assistive technologies?
  • Do forms, media, documents, and widgets expose useful information?
  • Are accessibility issues testable and repeatable?

ADA concerns often involve access

  • Can customers complete purchases or requests?
  • Can users access public information or services?
  • Can people complete forms, registrations, payments, or applications?
  • Can users consume videos, PDFs, documents, and instructions?
  • Can disabled users communicate effectively with the organization?
  • Are known barriers being addressed and documented?

When accessibility help is valuable

Accessibility help is valuable when a website, store, application, form, document library, media archive, or digital workflow may exclude users with disabilities or expose the organization to avoidable ADA or WCAG-related risk.

Common triggers

  • A website redesign or platform migration is planned.
  • An organization received an accessibility complaint or demand letter.
  • A public-sector or regulated project requires WCAG conformance.
  • Forms, checkout, applications, or account workflows may be inaccessible.
  • PDFs, documents, videos, or downloadable materials need review.
  • An accessibility overlay, plug-in, or widget is being considered or questioned.
  • Automated scans show issues but the remediation path is unclear.

Common business reasons

  • Reduce barriers for customers, members, students, patients, or constituents.
  • Improve e-commerce conversion and form completion.
  • Support procurement, grant, government, education, or enterprise requirements.
  • Improve brand trust and customer service.
  • Document a practical remediation plan.
  • Build accessibility into future design, development, and content workflows.
  • Reduce the chance of repeating the same accessibility problems.

Common accessibility barriers

Accessibility issues often come from ordinary design and development oversights: missing labels, low contrast, unclear errors, mouse-only controls, poor heading structure, inaccessible PDFs, unlabeled icons, videos without captions, custom widgets without keyboard support, or dynamic content that assistive technologies cannot understand.

Content and structure barriers

  • Missing or poorly written alternative text for meaningful images
  • Headings used for visual size rather than page structure
  • Links with vague text such as “click here” or “read more”
  • Tables without proper headers or captions
  • PDFs and documents without usable tags, reading order, or text alternatives
  • Instructions that rely only on color, shape, location, or visual cues
  • Complex language where plain instructions would help users complete tasks

Interface and code barriers

  • Form fields without programmatic labels
  • Errors that are not announced or explained clearly
  • Menus, modals, tabs, sliders, or filters that cannot be used by keyboard
  • Focus indicators that are hidden or hard to see
  • Color contrast that makes text difficult to read
  • Icons, buttons, and controls without accessible names
  • Dynamic updates that screen readers cannot detect or understand

Accessibility audits

An accessibility audit identifies barriers and organizes them into a practical remediation plan. Automated tools are useful for finding certain issues, but many important problems require manual review, keyboard testing, screen reader testing, code inspection, and workflow testing.

Recommended first move: Identify the highest-value workflows first: homepage, navigation, search, product pages, checkout, contact forms, account login, documents, videos, and any page that supports a legal, financial, medical, educational, government, or customer-service task.

Audit methods

  • Automated accessibility scans
  • Manual WCAG review
  • Keyboard-only testing
  • Screen reader inspection
  • Color contrast and visual review
  • Responsive and mobile accessibility review
  • Form, checkout, login, and document workflow testing

Audit deliverables

  • Issue inventory by page, component, or workflow
  • Severity and user-impact ranking
  • WCAG success criteria mapping where appropriate
  • Code-level remediation notes
  • Content and document remediation recommendations
  • Quick wins versus structural fixes
  • Retesting plan after remediation

Accessibility remediation

Remediation is the process of correcting accessibility barriers. The best fixes usually happen in the underlying HTML, CSS, JavaScript, templates, content model, design system, document process, and editorial workflow rather than as a last-minute visual adjustment.

Common code fixes

  • Correct heading hierarchy and semantic landmarks
  • Add proper labels, descriptions, and error associations to forms
  • Improve keyboard behavior for menus, dialogs, tabs, filters, and custom controls
  • Add accessible names to buttons, links, and icon controls
  • Improve focus order and visible focus states
  • Use ARIA carefully where native HTML is insufficient
  • Ensure dynamic updates are announced when needed

Common content fixes

  • Write meaningful alternative text for informative images
  • Use descriptive link text and clear button labels
  • Add captions, transcripts, and audio descriptions where appropriate
  • Improve instructions, help text, and error messages
  • Remediate PDFs and documents or provide accessible HTML alternatives
  • Make tables, charts, and diagrams understandable to non-visual users
  • Review page copy for clarity, sequence, and task completion

E-commerce, forms, and checkout accessibility

E-commerce accessibility deserves special attention because barriers can directly prevent customers from buying. Product browsing, filters, cart updates, account login, shipping estimates, payment forms, coupon fields, address validation, and order confirmation all need to work for keyboard users, screen reader users, users with low vision, and users who need more time or clearer instructions.

Shopping barriers

  • Product options that cannot be selected by keyboard
  • Color, size, price, or availability conveyed only visually
  • Filters and sort controls without accessible labels or state
  • Product images without meaningful descriptions
  • Cart updates that are not announced
  • Checkout errors that are hard to find or understand
  • Payment iframe or gateway controls with accessibility issues

Practical improvements

  • Use accessible labels and instructions for every form field.
  • Group related fields with clear structure.
  • Make validation errors visible, understandable, and programmatically associated.
  • Preserve user input after errors.
  • Make cart and checkout updates detectable to assistive technologies.
  • Test third-party payment and shipping components.
  • Confirm the full purchase path works without a mouse.

If the project involves an online store, review the E-commerce getting started guide.

Documents, PDFs, video, and media

Accessibility is not limited to websites. PDF files, Word documents, spreadsheets, slide decks, videos, webinars, podcasts, image galleries, charts, maps, and downloadable forms may all create barriers if they are not prepared correctly.

Document concerns

  • Scanned PDFs that contain images of text instead of selectable text
  • Incorrect reading order
  • Missing headings, tags, bookmarks, or table structure
  • Forms that cannot be completed with assistive technologies
  • Charts or images without text alternatives
  • Documents that are easier to provide as accessible HTML pages

Media concerns

  • Videos without captions
  • Audio without transcripts
  • Important visual information without audio description or text equivalent
  • Autoplaying media that disrupts users
  • Players that cannot be operated by keyboard
  • Embeds that lack accessible titles or controls

Third-party tools, overlays, and widgets

Many accessibility problems come from third-party tools: chat widgets, review widgets, booking tools, payment iframes, embedded forms, maps, video players, ads, tracking tools, social embeds, calendars, and plug-ins. These components should be reviewed because they can create barriers even when the surrounding website is well built.

Overlay caution: Accessibility overlays and widgets may provide limited user-preference features, but durable accessibility usually requires fixing the underlying content, templates, code, forms, media, and workflows.
  • Review vendor widgets: Test chat, scheduling, payment, review, and marketing widgets with keyboard and screen reader workflows.
  • Check embedded forms: Ensure labels, errors, instructions, and submit behavior remain accessible.
  • Watch performance and focus: Third-party scripts can affect focus order, page speed, modals, popups, and mobile usability.
  • Document limitations: If a vendor component cannot be made accessible, document the limitation and evaluate replacement or alternate access paths.

Accessibility as an ongoing workflow

Accessibility is easiest to maintain when it becomes part of ordinary design, development, content, quality assurance, and publishing workflows. A site can pass an audit and later regress when new templates, plug-ins, campaigns, forms, videos, documents, or product data are added without review.

Sustainable practices

  • Use accessible design-system components.
  • Include keyboard and screen reader checks in QA.
  • Train content editors on headings, links, images, tables, and documents.
  • Require accessible media workflows for captions and transcripts.
  • Review new plug-ins and third-party tools before launch.
  • Track accessibility issues like other production defects.
  • Retest high-value workflows after releases.

Helpful documentation

  • Accessibility issue backlog
  • Remediation notes and code examples
  • Accessibility statement or feedback channel
  • Content editor checklist
  • Template and component accessibility notes
  • Third-party component limitations
  • Retesting and monitoring plan

Accessibility assessment checklist

Before beginning an accessibility project, identify the digital assets, workflows, compliance expectations, and user paths that matter most.

Useful decision factors

  • Whether the project is driven by usability, procurement, compliance, complaint response, redesign, or risk reduction
  • Target WCAG version and conformance level
  • ADA, Section 508, contractual, public-sector, or industry-specific expectations
  • Business impact of inaccessible forms, checkout, documents, or service workflows
  • Volume and importance of PDFs, videos, product pages, forms, and third-party tools
  • Current design-system, content-management, and development constraints
  • Availability of staff to maintain accessibility after remediation
  • Need for legal review, policy language, or formal compliance documentation

Typical deliverables

  • WCAG accessibility audit
  • ADA-focused technical accessibility review
  • Issue backlog with severity and remediation guidance
  • Keyboard and screen reader testing notes
  • Form, checkout, and e-commerce accessibility review
  • PDF, document, and media accessibility recommendations
  • Third-party widget and overlay review
  • Code-level remediation support
  • Accessibility statement and feedback-channel guidance
  • Ongoing accessibility workflow plan

When an accessibility consultation makes sense

An accessibility consultation is most useful when a website, application, store, document library, form, or digital service needs practical review against WCAG and ADA-related expectations. The work may be preventive, tied to a redesign, driven by a complaint, required for procurement, or part of a larger usability and quality improvement effort.

Good reasons to ask for help

  • You need to understand whether a website meets WCAG expectations.
  • You received an ADA-related accessibility complaint or demand letter.
  • You are redesigning or rebuilding a website and want accessibility built in.
  • Your forms, checkout, login, or account workflows may block users.
  • You need PDFs, videos, documents, or downloads reviewed.
  • You use third-party widgets, overlays, plug-ins, or embedded tools that may create barriers.
  • You need a remediation plan developers and content editors can act on.
  • You want an ongoing workflow so the site does not regress after fixes.

Good questions to answer first

  • Which standard or requirement is driving the project?
  • Which pages and workflows are most important?
  • Are there existing complaints, audit reports, or automated scan results?
  • Who can change templates, code, content, PDFs, media, and third-party tools?
  • Which barriers prevent users from completing important tasks?
  • What timeline is tied to launch, procurement, remediation, or legal review?
  • Who will maintain accessibility after the first round of fixes?
