Beginner LevelHTML & Semantic Web
Why is heading hierarchy (<h1> through <h6>) critical for web accessibility?
❓ Interview Prompt: Explain heading level hierarchy, avoiding skipped heading levels, single <h1> per page, and screen reader outline navigation.
Headings ('<h1>' through '<h6>') establish a hierarchical document outline:
Best Practices:
1
Single '<h1>': Each page should have one primary '<h1>' describing the core topic.
2
Never Skip Levels: Do NOT jump from '<h1>' directly to '<h3>' for visual styling (use CSS for font size!).
3
Screen Reader Navigation: Visually impaired users press the 'H' key to jump between headings to skim document outlines.
Code Implementation Example
html
<h1>Main Page Title</h1>
<section>
<h2>Topic Heading</h2>
<h3>Sub-topic Detail</h3>
</section>💡Sequential heading hierarchy maintaining logical document outline.
🎯 Interview Key Takeaway
Maintain sequential heading levels (h1 -> h2 -> h3) without skipping levels for screen reader navigation.
