**Alt Text**
*Definition:* Alt text, short for “alternative text,” is a textual description of an image or graphic displayed on a webpage.

*Purpose:* The primary purposes of alt text are to improve accessibility for individuals with disabilities, enhance the user experience by providing context, and aid in the indexing of images by search engines, thereby contributing to better SEO (Search Engine Optimization).
*Usage:* Alt text should be concise yet descriptive enough to convey the essence of the image.
