  • Contrast Ratio: Maintain a sufficient contrast ratio between text and background colors to make content readable for low-visioners.
     

  • Descriptive Links: Use clear and descriptive link text. Avoid generic phrases like "click here" or "read more."
     

  • Video and Audio Accessibility: Provide captions for videos and transcripts for audio content to accommodate users with hearing impairments.
     

  • Form Accessibility: Ensure that forms are accessible and include proper field labels. Users with disabilities should be able to complete forms efficiently.
