The large promotional banner at the top of the Walmart page automatically rotates between images, which creates an accessibility issue. Module 2 explains that many users with motor impairments rely on assistive technologies like adaptive keyboards, head wands, or single-switch devices, and these tools cannot easily pause or control moving content. When the carousel changes on its own, it can move too quickly for screen readers to finish reading the text and makes navigation harder for users who cannot use a mouse. Because the movement happens without user input and may not offer clear pause controls, it fails the "Operable" principle by reducing user control over the interface.

Each product tile on the Walmart page uses proper HTML structure for elements like product names, prices, and "+Add" buttons. Module 2 explains that content must be readable by a wide range of assistive technologies, including screen readers, braille displays, and screen magnifiers. Because these elements are coded in a way that tools like NVDA, ChromeVox, and braille readers can interpret, users with visual or motor impairments can reliably access the same information. This supports the "Robust" principle by ensuring the page remains usable across different devices, browsers, and assistive technologies as they evolve.

The search bar at the top of the Walmart page can be accessed and used with only a keyboard, without requiring mouse-based actions like hovering. Module 2 explains that not all users can operate a mouse, especially those with motor impairments, so interactive elements must be useable through alternative input methods. Because the search bar supports keyboard navigation, it follows the "Operable" principle by allowing users to interact with the interface in multiple ways.

This section places text directly on top of a detailed background image, which reduces contrast and makes the writing harder to read. Module 2 explains that colour should never be the only cue for communicating information, and text needs strong, consistent contrast from its background to stay "Perceivable." Because the images behind the text have many colours and textures, the contrast changes and the words become less clear for users with low vision, colour-vision deficieincies, or anyone viewing the page in bright light.

This Walmart section shows many promotional tiles at once, each with different colours, images, and text styles. As Module 2, explains users with dyslexia, ADHD, or autism can struggle with cluttered or visually busy designs because they increase cognitive load. Since the layout is not simple or predictable, it violates the "Understandable" principle by making the content harder to process.
