What is it and why is it important?
Alt tags, also known as alternative text or alt text, are HTML attributes used to describe the content of images on a web page. Alt tags are an important part of web accessibility, helping users with visual impairments to understand the purpose of images on a page. Additionally, alt tags can improve search engine optimization (SEO) by providing additional context to search engines about the content of a web page.

Alt tags provide important information to users who may not be able to see an image. Screen readers, for example, can read out the alt text to users with visual impairments, helping them to understand the content and purpose of an image on a web page. Additionally, alt tags can improve the SEO of a web page by providing search engines with additional context about the content of an image.
