Chapter 11 offers eleven guidelines for designing accessible websites. Two of the guidelines are to provide appropriate alternative text and to provide appropriate document structure. What are two other guidelines?

Two other guidelines for designing accessible websites, in addition to providing appropriate alternative text and appropriate document structure, are:

1. Ensure Keyboard Accessibility: Make sure that all interactive elements on the website can be accessed and used through keyboard commands alone. This is crucial for users who cannot use a mouse due to physical disabilities or who prefer keyboard navigation. Elements such as links, buttons, and form controls should be navigable using the Tab key, and actions should be executable using Enter or Spacebar.

2. Use Sufficient Color Contrast: Ensure that there is enough contrast between text and background colors to make the content easily readable for users with visual impairments, including those who are color blind. The Web Content Accessibility Guidelines (WCAG) provide specific contrast ratio recommendations to ensure that text stands out against its background, making it legible for users with varying degrees of visual acuity.
