Step-by-step explanation:
Web sites can use design techniques, scripts, images, and graphics in ways that make the content inaccessible or difficult to use. One way this can happen is through poor design decisions early in the process, which can lead to a design that doesn't meet the needs of users. Another way is by not providing alternative text or descriptions for images and graphics, making it difficult for those with visual impairments to understand the content. Additionally, compatibility issues, visibility problems on different devices, and incorrect sizing or placement of images can also make the content inaccessible.
