What does semantics refer to in web development?

Semantics in web development refers specifically to the practice of giving meaning and structure to content on a web page through the use of proper HTML elements. This approach allows developers to use HTML tags that not only format the content but also convey the intended meaning to both the web browser and users. For example, using headings, paragraphs, lists, and other appropriate elements helps search engines better understand the content’s hierarchy and purpose, which can improve search engine optimization (SEO) and accessibility.

Utilizing semantic HTML improves the overall user experience by making content more understandable and navigable. It also assists assistive technologies, like screen readers, in accurately interpreting and conveying the structure of the content to users with disabilities. This context enhances the importance of semantics in creating well-structured and meaningful web pages, ensuring that the content is presented logically to all users.

Other options refer to different concepts: one focuses on the rules of symbols in documents (related to syntax), another pertains to data analysis, and the last one involves creating interactive features, none of which specifically address the meaning and structure of content through proper elements as semantics does.
