Heading Hierarchy refers to the logical and nested structure created by using HTML heading tags (<h1> to <h6>) to organize content on a web page. This hierarchy is crucial for both user experience and search engine optimization.
A proper heading hierarchy starts with a single <h1> for the main topic, followed by <h2> tags for major sections, <h3> for sub-sections within those, and so on. This structure helps users quickly scan and understand the content's flow and importance. For search engines, it signals the relationships between different content sections, aiding in topic understanding and potentially improving visibility in rich snippets.
For example:
<h1>Mastering Modern CSS Layouts</h1><h2>Introduction to Flexbox</h2><h3>Basic Flex Container Properties</h3><h3>Aligning Items with Flexbox</h3><h2>Deep Dive into CSS Grid</h2><h3>Defining Grid Templates</h3><h3>Responsive Grid Design</h3>
This clear structure makes the content digestible and SEO-friendly.
