What is the purpose of semantic HTML in web development?

Semantic HTML plays a crucial role in web development by providing structure and meaning to web content, which directly aids accessibility. When developers use semantic HTML, they apply elements that clearly define the roles of their content. For example, using headings to represent sections, lists to convey items in a sequence, and paragraph tags for text creates a clear hierarchy and meaning for both users and assistive technologies, such as screen readers.

This clarity helps individuals with disabilities navigate and understand the content more effectively. Semantic elements convey the purpose and context of the enclosed content, enhancing the user experience by ensuring that everyone, regardless of their ability, can access and interpret the information presented on the page. This is especially vital for compliance with accessibility standards and guidelines, which advocate for inclusivity in digital environments.
