Accessibility Practice: Needs improvement. The homepage has a busy layout with the large number of promotional boxes and advertisements displayed all at once. This busy layout may create cognitive overload for users with dyslexia, ADHD, or other cognitive disabilities. This further relates to the Understandable principle since overly cluttered webpages can make it challenging for users to process information, focus, and navigate efficiently.

Accessibility Practice: Needs improvement. I noticed that the homepage relies heavily on images to communicate their sales and promotions. If these images don't contain descriptive alt text, the screen reader users who are blind or visually impaired may miss the important deals and information. Furthermore, the Robust and Perceivable aspects of accessibility would be improved with the addition of detailed alt text.

Accessibility Practice: Good Practice. This menu highlights the Understandable principle since the categories are located at the beginning of the website and they are clearly organized. The consistent navigation helps users with cognitive disabilities, as well as, it improves screen reader navigation by creating a logical page structure. The organization of the menu further allows user to instantly understand and find items of interest on the website without getting confused and frustrated.

Accessibility Practice: Good Practice. The "Shop Now" buttons on the Staples website are large, spaced apart from other elements, and clearly labelled. This makes them easier to click for users that may have motor impairments or other limited hand precision, further improving the website's overall navigation. Thus, "Shop Now" are large clickable buttons, making them support the Operable principle.

Accessibility Practice: Good practice. The Staples website homepage is perceivable due to the strong colour contrast. For example, the black background with white lettering for the "Chair + Desk Event" improves readability for the users with colour blindness or low vision. The style of text and large font size are also easy to understand and it attracts the user's attention. This further supports the WCAG principle of being perceivable.
