HTML5 Section Element (Live Playground)


The <section> element in HTML5 is a semantic element used to define a section of content that is thematically related and can be treated as an independent unit. In this tutorial, you will learn how to use the <section> element to create structured and accessible content sections within your web pages, including common use cases and best practices.

Using the <section> Element

The <section> element is used to group related content within a web page, such as chapters, articles, or other thematic groupings. The content inside a <section> should be related and have a common purpose.

Here's an example of using the <section> element to create a simple content section:

<!DOCTYPE html>
<html lang="en">
<meta charset="UTF-8" />
<title>HTML5 Section Example</title>
<h1>My Website</h1>
<!-- Navigation menu -->
<h2>About Us</h2>
<p>Welcome to our website! We are a small company specialized in web development.</p>
Our team is composed of experienced professionals who are passionate about creating high-quality web solutions
for our clients.
<!-- Footer content -->

In this example, the <section> element is used to create a content section within the <main> element. The section contains an <h2> heading and two paragraphs.

Nesting the <section> Element

The <section> element can be nested within other elements, such as the <main>, <article>, or <aside> elements, depending on the layout and design of your web page. For example, you can use nested <section> elements to create subsections within an <article> element:

<h1>Web Development Trends in 2023</h1>
<h2>Progressive Web Apps</h2>
Progressive Web Apps (PWAs) are a popular trend in web development, providing users with a seamless experience
across devices.
<h2>Serverless Architecture</h2>
Serverless architecture is gaining traction as a cost-effective and scalable solution for web applications,
enabling developers to focus on writing code without worrying about infrastructure management.

Best Practices

When using the <section> element, consider the following best practices:

  1. Use the <section> element to group related content that forms a cohesive unit within your web page. Do not use it as a generic container for styling purposes; use the <div> element instead.

  2. Include a heading within each <section> element to provide a clear description of the content and improve accessibility.

  3. Use the <section> element in combination with other semantic elements to create a well-structured and accessible web page. For example, use the <main> element for the main content, the <header> and <footer> elements for the header and footer, and the <article> and <aside> elements for content and sidebars respectively.

  4. Nest <section> elements when necessary to create a hierarchy within your content. However, avoid excessive nesting, as it can make your web page structure more complex and harder to maintain.

  5. Make your content accessible by providing meaningful and descriptive headings for each <section> element. This helps screen reader users and search engines understand the structure of your content.


The <section> element is an essential part of HTML5, allowing you to create well-structured and accessible content sections within your web pages. By understanding its purpose and how to use it effectively, you can create websites that are both user-friendly and optimized for search engines.

Remember that the key to mastering HTML5 and semantic elements is practice and patience. Keep building web pages, incorporating these semantic elements, and experimenting with different layouts and designs. As you gain experience, you'll develop a better understanding of how and when to use each element to create accessible and well-structured web content.
