Semantics accurately represent the structure and purpose of content in computer languages like HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript, enabling web developers and programmers to ensure the written code produces an output legible to humans and machines.

For example, using semantic tags such as <h1> for important headings and <p> for paragraphs instructs HTML semantics to render the corresponding elements accordingly, guaranteeing that the intended structure appears on the website.

Accurate semantics play a crucial role in improving search engine optimization (SEO) by helping search engines like Google and Bing understand and rank web content. Semantics also enhance accessibility for users who rely on assistive technologies, such as screen readers, by interpreting and presenting the content as intended.
