When creating web pages, it is important to include alternative text (alt text) that describes the images on the page. This allows visitors who are unable to see the images on the page to still understand what is on the page.
Alt text is especially important for those who are visually impaired or blind, as they use screen readers to read the alt text of images on a web page. Screen readers are software programs that allow users to hear the contents of a web page.
Including alt text also helps search engines index your website and understand what is on each page. When writing alt text, be sure to describe what is happening in the image and why it is relevant to the rest of the content on the page.
