Introduction to the <section> Element
The <section> element is a versatile HTML5 element used to group related content together within a webpage. It is a semantic element, meaning it conveys meaning about the content it wraps, helping to improve the structure and accessibility of your website. The <section> element is particularly useful when you need to divide your content into thematic groups, each with its own heading.
Purpose of the <section> Element
The primary role of the <section> element is to organize content into distinct sections that are logically connected. These sections typically represent different parts of the document that contribute to the overall content theme. This element can be used multiple times within a webpage to separate and group various topics or ideas.
Basic Usage of the <section> Element
The <section> element should be used to group related content together. Each section should have a heading, usually an <h1>, <h2>, or <h3>, to define the content within the section. Unlike the <div> element, which is used purely for layout purposes, the <section> element adds meaning to the content it contains.
Example:
<section>
<h2>About Us</h2>
<p>We are a company dedicated to providing high-quality products and services.</p>
</section>
<section>
<h2>Our Services</h2>
<p>We offer a wide range of services to meet your needs, including web development, design, and consulting.</p>
</section>In this example, each <section> groups related content together under a common theme, making it easier for users and search engines to understand the structure of the page.
Best Practices
- Use the <section> element to group content that belongs together thematically.
- Each <section> should start with a heading to clearly define the content within the section.
- Avoid using <section> purely for styling or layout purposes; use it to add semantic meaning to the content.
- Combine <section> with other semantic elements like <article>, <aside>, and <header> for a well-structured document.
