Introduction to Semantic Elements

Semantic HTML refers to the use of tags that clearly describe the purpose of the elements in a web page. This helps search engines and assistive devices better understand the structure and content of the page, improving accessibility and search engine optimization.

Sections and Articles (<header>, <footer>, <section>, <article>)

Some of the most common semantic tags are <header> and <footer> for headers and footers, <section> to group content thematically, and <article> for standalone content.

Aside, Nav, and Main Elements (<aside>, <nav>, <main>)

Other important tags include <aside> for related content, <nav> for navigation, and <main> for the main content of the page. These tags enhance the organization and navigation of the site.

Accessibility with Semantic HTML

The use of semantic HTML contributes to accessibility, allowing assistive devices, such as screen readers, to interpret and navigate the content efficiently. This also benefits users with disabilities, as semantic elements make the page structure clearer.

For example, a screen reader identifies the <nav> tag as a navigation area, allowing the user to jump directly to the menu instead of reading all the content.
