Using Headings for SEO
SEO Benefits
Properly using headings can improve your site's SEO. Search engines give more weight to headings when indexing your page, so using relevant keywords in headings can boost your search ranking.
<h1>Main Topic</h1>
<h2>Subtopic 1</h2>
<h2>Subtopic 2</h2>
<h3>Detail 1 under Subtopic 2</h3>
<h3>Detail 2 under Subtopic 2</h3>
Accessibility Considerations
Using headings correctly also improves accessibility, as screen readers use them to help users navigate the page.
Styling Headings with CSS
Customizing Appearance
You can style HTML headings using CSS to fit the design of your website. This includes changing font size, color, and other text properties.
h1 {
font-size: 2em;
color: #333;
}
h2 {
font-size: 1.5em;
color: #666;
}
Responsive Design
Ensure your headings are responsive by using relative units like em or rem, which scale with the user's default font size.
Best Practices for Headings
Use Headings Hierarchically
Always use headings in a hierarchical order. Start with <h1> for the main title, followed by <h2> for sub-sections, and so on. Avoid skipping heading levels.
<h1>Main Title</h1>
<h2>Section Title</h2>
<h3>Subsection Title</h3>
<h4>Detail Title</h4>
Avoid Using Headings for Style
Do not use headings solely for styling purposes. Instead, use CSS classes to apply styles to any text element.
Combining Headings with ARIA
Enhancing Accessibility with ARIA
Use ARIA roles to enhance the accessibility of your headings. This helps assistive technologies better understand the structure of your content.
<h1 role="heading" aria-level="1">Main Title</h1>
<h2 role="heading" aria-level="2">Section Title</h2>
ARIA Levels
Specify the level of each heading using aria-level to maintain the correct hierarchy for users relying on assistive technologies.
HTML headings are fundamental for structuring content effectively.
Understand the hierarchy from <h1> to <h6>.
Focus on accessibility and semantic correctness for professional-grade webpages.
