What is the primary purpose of the Alt attribute in an Img Tag?

The primary purpose of the Alt attribute in an Img tag is to provide alternative text for an image. This attribute is essential for several reasons. It serves as a textual substitute for images, ensuring that the content remains accessible to users who may be unable to see the images, such as those using screen readers or individuals with visual impairments. If an image fails to load, the alt text will be displayed in place of the image, giving users context about what the image represents.

This enhances the user experience and helps with search engine optimization, as search engines use the alt text to understand the content of the image, potentially improving visibility in search results. Furthermore, providing descriptive alt text contributes to the overall accessibility of a web page, aligning with best practices in web development and design.

The other options primarily focus on different functionalities that are not related to the alt attribute: hyperlinks, image maps, and styles have distinct purposes in HTML that do not pertain to providing alternative text for images.
