Problem Statement
Explain the semantic meaning of heading hierarchy.
Explanation
Heading hierarchy in HTML refers to the structured use of heading tags from h1 to h6 to organize content in a logical, hierarchical manner. This hierarchy has important semantic meaning for browsers, search engines, and assistive technologies. The h1 tag represents the most important heading and should typically be used once per page for the main title. The h2 tags are used for major sections, h3 for subsections within those sections, and so on. This creates a clear outline of your content structure. Proper heading hierarchy is crucial for several reasons. First, search engine optimization. Search engines use headings to understand the structure and main topics of your page. The h1 carries the most weight for search engine optimization. Second, accessibility. Screen readers use heading hierarchy to help visually impaired users navigate your page. Users can jump between headings to quickly find the content they need. Third, user experience. Clear headings make content scannable and easier to read. Users can quickly identify main topics and subtopics. Best practices include: never skip heading levels, such as going from h2 directly to h5. Use headings in order. Do not use headings just for styling purposes. If you need larger or smaller text, use CSS instead. Each page should have one h1 tag. Use heading tags for structure, not for making text bigger. Understanding and implementing proper heading hierarchy demonstrates professional web development skills and is often discussed in technical interviews.
