Frequently Asked Questions
What are semantic HTML elements?
Semantic HTML elements are tags whose names describe the meaning or role of their content — `<nav>` for navigation, `<article>` for a self-contained piece of content, `<footer>` for page or section footer. Contrast with non-semantic elements like `<div>` and `<span>`, which carry no inherent meaning.
Why should I use semantic HTML?
Semantic HTML helps search engines understand page structure, improves screen reader navigation through landmark regions, makes code more maintainable, and can unlock rich results in Google (breadcrumbs, sitelinks, etc.) when combined with structured data.
What is the difference between div and section?
`<div>` is a generic container with no semantic meaning — for styling and layout. `<section>` represents a thematic grouping of content that typically has its own heading. Use `<section>` when the content is a distinct part of the page; use `<div>` when you just need a styling hook.
How do semantic elements help SEO?
Search engines use semantic structure to understand the content hierarchy — `<h1>` through `<h6>` headings establish document outline, `<article>` signals independent content, and `<nav>` helps identify site structure. Proper semantics can also qualify pages for rich results.
What is a landmark region in HTML?
Landmark regions are semantic elements that define major page areas for assistive technology: `<header>`, `<nav>`, `<main>`, `<aside>`, `<footer>`, and `<form>`. Screen reader users navigate between landmarks like chapters — they skip over entire sections to reach the area they want.
