What is Alt Attribute?

Alt Attribute - also known as "alt tag" or "alt text," is a HTML attribute added to images that describe the visual content of an image. It helps visually impaired users who use screen readers to understand what an image represents on a website.

The alt attribute is also used by search engine crawlers to index images, which can help with website accessibility and SEO optimization. A well-crafted alt attribute provides context for the image and enhances the overall user experience of your website.

In addition to its practical uses, the alt attribute also has aesthetic benefits, allowing web designers to add a descriptive caption or message when someone hovers over an image with their mouse.
