Semantic HTML
Semantic HTML is a way of writing HTML that makes the meaning of the content more explicit. This makes it easier for browsers, search engines, and assistive technologies to understand the content of a web page.
Semantic HTML uses elements that have a specific meaning, such as <header>
, <article>
, and <footer>
. These elements tell the browser what the content of the element is, which makes it easier for the browser to render the content correctly and to pass the content on to search engines and assistive technologies.
Here is an example of a semantic HTML document:
This document uses the <header>
, <article>
, and <footer>
elements to define the header, article, and footer of the document. This makes it clear to the browser what the content of each section is, which helps the browser to render the content correctly and to pass the content on to search engines and assistive technologies.
Benefits of Semantic HTML
There are several benefits to using semantic HTML:
- It makes the content of a web page more accessible. Assistive technologies, such as screen readers, can use the semantic meaning of the elements to help people with disabilities understand the content of a web page.
- It makes it easier for search engines to index the content of a web page. Search engines can use the semantic meaning of the elements to understand the content of a web page, which can help the page to rank higher in search results.
- It makes it easier for web developers to work with the content of a web page. The semantic meaning of the elements can help web developers to understand the structure of a web page, which can make it easier to make changes to the page.
Examples of Semantic HTML Elements
Here are some examples of semantic HTML elements:
- <header> – This element defines the header of a document.
- <article> – This element defines an independent, self-contained piece of content.
- <section> – This element defines a section of a document.
- <footer> – This element defines the footer of a document.
- <nav> – This element defines a navigation bar.
- <aside> – This element defines content that is aside from the main content of a document.
