Understanding ALT Text
ALT Text, short for 'Alternative Text', is a textual substitute for visual elements on digital platforms, designed to provide a comprehensive and equivalent experience for users who are unable to perceive these elements visually. Its primary purpose is to ensure accessibility, enabling screen readers and other assistive technologies to interpret and convey the content of images, videos, and other non-textual elements to visually impaired or blind users. For example, an image of a bustling city street might have an ALT Text description that reads, 'A busy city street scene with pedestrians walking on the sidewalks and cars driving on the road, with tall buildings lining either side under a clear blue sky.' This detailed description attempts to capture the essence and specific details of the visual content, offering a vivid mental image for those who cannot see it. Powered by ChatGPT-4o。
