How does alt attribute improve accessibility?

The alt attribute improves accessibility in several ways:

Screen Readers: For users who are visually impaired and use screen readers, the alt text provides a description of the image. This allows them to understand the content and context of the image.
Image Loading Issues: If an image fails to load, the alt text will be displayed in its place. This gives users an idea of what the image was supposed to convey.
Search Engine Optimization (SEO): While not directly related to accessibility, alt text can help search engines understand the content of images, potentially improving the visibility of the webpage.
Contextual Understanding: The alt attribute can provide context for images that are essential to the content, ensuring that all users, regardless of their ability, can grasp the full message of the page.

By including descriptive alt text, you enhance the user experience for individuals with disabilities and ensure that your content is more inclusive.
