HTML headings are used to define headings and subheadings on a web page. They provide structure and hierarchy to your content, making it easier for both users and search engines to understand the page's organization.

There are six levels of headings, from <h1> to <h6>, with <h1> being the most important and <h6> the least.

Structure and Usage

  • Hierarchy: Headings should be used in a logical order, starting with <h1> for the main heading and progressing to lower levels for subheadings.
  • One <h1> per page: It's generally recommended to use only one <h1> element per page to represent the main title.
  • Consistency: Maintain a consistent heading structure throughout your page. Don't skip levels (e.g., don't go from <h1> to <h3> without an <h2>).

Example

HTML
<!DOCTYPE html>
<html>
<head>
  <title>Heading Example</title>
</head>
<body>

<h1>This is the main heading</h1>

<h2>Section 1</h2>
<p>Content for section 1.</p>

<h3>Subsection 1.1</h3>
<p>Content for subsection 1.1.</p>

<h2>Section 2</h2>
<p>Content for section 2.</p>  

<h3>Subsection 2.1</h3>
<p>Content for subsection 2.1.</p>

<h4>Subsubsection 2.1.1</h4>
<p>Content for subsubsection 2.1.1.</p>

</body>
</html>

Importance of Headings

  • User experience: Headings help users quickly scan a page and find the information they need.
  • Accessibility: Screen readers use headings to navigate content, making your website accessible to people with visual impairments.
  • SEO: Search engines use headings to understand page structure and content, which can improve your search rankings.
