Semantic HTML refers to the use of HTML elements that convey meaning or semantics to the content of a web page. In other words, it’s using HTML tags that accurately describe the type of content they contain.
Semantic HTML is important for several reasons. Firstly, it improves accessibility for users with disabilities such as vision impairment or cognitive impairments by making it easier for screen readers to interpret and understand the content of the page. Secondly, it improves search engine optimization (SEO) by providing search engines with a clearer understanding of the page’s content and structure. Lastly, semantic HTML improves the readability and maintainability of the code, making it easier for other developers to understand and modify the code.
Some examples of semantic HTML elements include:
<header>: used to define the top section of a web page, typically containing the site’s logo and primary navigation.<nav>: used to define a set of navigation links for a web page.<main>: used to define the main content area of a web page.<section>: used to group related content on a web page.<article>: used to define a self-contained piece of content, such as a blog post or news article.<footer>: used to define the bottom section of a web page, typically containing copyright information and other relevant links.
By using these and other semantic HTML elements, web developers can create web pages that are more accessible, readable, and maintainable.
