Understanding Alt Text (Alternative Text)
Alternative text is a text description added to images in HTML. It serves multiple purposes: providing context for screen reader users, displaying when images fail to load, and helping search engines understand image content. Good alt text is concise, descriptive, and contextual. It should convey the image's purpose and content without being overly long. Decorative images may have empty alt attributes to be skipped by screen readers.
