### Long Definition
Alt text, short for "alternative text," is a descriptive attribute used in HTML to provide text-based information about images on webpages. It is essential for accessibility purposes, as it helps individuals who are visually impaired or using screen readers to understand the content and function of images. Alt text is added to the <img> tag as the "alt" attribute, like this: <img src="image.jpg" alt="Description of the image">. The text within the alt attribute should concisely describe the image's content or convey the message it conveys. Alt text serves several important functions:
1. Accessibility: Alt text enables users who are visually impaired or using screen readers to comprehend the purpose and context of images on a webpage.
2. SEO: Search engines use alt text to understand the content of images, which can contribute to better indexing and ranking in search results.
3. Fallback: In cases where an image cannot be displayed due to slow internet connection or other technical issues, alt text provides a fallback option, ensuring that users still receive meaningful information.
4. Image Optimization: Alt text encourages the use of descriptive keywords related to the image, which can improve the webpage's relevance and visibility in search engine results.
When writing alt text, it's essential to be descriptive but concise, providing relevant information without being overly verbose. Alt text should accurately represent the image while also considering the context in which it appears on the webpage. Properly implemented alt text enhances accessibility, improves SEO, and contributes to a better user experience for all visitors to the website.
