Web Accessibility testing

Explore the concept of accessibility as the design of usable products for people with disabilities. See how keyboard, ramp, screen readers, and step by step forms improve universal digital usability.

Explore how visual, hearing, motor, and cognitive disabilities affect web accessibility, and learn to test with screen readers, captions, keyboard navigation, color contrast, and simple layouts.

Explore wcag 2.0 and 2.1, levels a, aa, and aaa, and the four principles: perceivable, operable, understandable, robust.

Learn how assistive technologies like screen readers (JAWS, NVDA, Narrator, VoiceOver, TalkBack) and refreshable Braille enable keyboard-only access, and why keyboard functionality and HTML structure matter in accessibility testing.

Explore how HTML landmarks create a semantic layout with header, main, sidebar, and footer, and learn to test screen reader navigation using Nvda shortcuts.

Explore semantic html elements and nvda screen reader behavior for headings, lists, and landmarks, contrasting with non-semantic markup to improve accessibility testing.

Learn the HTML table structure with table, tr, th, and td, featuring four columns, and how screen readers interpret it, including image alt text and headings, lists, and tables.

Use axe devtools to automate accessibility testing on a website, scan pages for issues, and review severity levels from critical to minor, with guided fixes and reporting.

Explore how Wave validates accessibility, reveals color contrast issues, heading order problems, and attributes, and learn to interpret reports for automated and manual testing.

Introduce manual testing for web accessibility, focusing on keyboard operability via tab navigation and activation with enter or spacebar. Ensure screen reader compatibility and focus indicators.

Learn how accessibility testing begins in design, focusing on responsiveness and readability, plus color contrast, target size, meaningful content, and complexity to ensure readable, usable web experiences.

Improve web accessibility by checking readability, reading order, and typography, and apply WCAG 2.1 1.4.12 spacing and color contrast tests with a color contrast analyzer.

Ensure target size of 44 by 44 pixels for icons and buttons to be easily clickable on small screens and dexterity issues, use meaningful content and provide pause for motion.

As an accessibility tester, log image issues by documenting alternative text for each image, verify 15 images, and ensure alt text conveys meaning or remains empty for decorative images.

Initiate web accessibility testing by running automation tools on a defined scope, identify critical issues, and document labeled fixes with descriptive notes and screenshots.

Use automation tools to identify accessibility issues, then conduct manual keyboard testing to verify focus indicators and focusable elements in the navigation bar, documenting findings with screenshots and issue reports.

Explore aria-label and other aria attributes using the Mozilla developer site, see how invisible labels provide screen reader access, override visible text, and inform users about links opening in tabs.

Explore how aria attributes convey state for custom widgets, using aria-expanded and aria-checked with roles like combo box, to support screen readers and keyboard navigation.

Discover how role attributes and ARIA roles change non-semantic elements into accessible links, buttons, and headings, using tab index and screen reader behavior to illustrate focus and presentation.

Mastering focus management for web accessibility by testing focus trapping in modal dialogs, ensuring keyboard users tab through elements and screen readers announce the correct focus changes and alerts.

Create a final accessibility report documenting WCAG conformance levels, severity, actual vs expected results, and QA status, including name, URLs, date, author, and testing method.
