What Are HTML Elements?

Many developers overlook the importance of using proper HTML elements.

Run

<p>This is a paragraph.</p>  

Here, <p> is the opening tag, This is a paragraph. is the content, and </p> is the closing tag.

Some elements, like <img> or <br>, are self-closing and don’t need a closing tag.

Common HTML Elements and Their Uses

1. Semantic Elements

Beyond basic structure, semantic elements clarify content meaning for browsers and assistive tools:

  • <article>: Self-contained content (e.g., blog post, news story).
  • <section>: Thematic grouping (e.g., chapter, product features).
  • <nav>: Navigation menu links.
  • <aside>: Supplementary content (e.g., sidebar, pull quotes).
  • <time>: Machine-readable dates (<time datetime="2023-10-05">Oct 5</time>).

Why semantics matter:
✅ Screen readers interpret page structure accurately.
✅ Search engines prioritize well-labeled content.
✅ Developers quickly understand code organization.

2. Interactive Elements

Enhance user engagement with:

  • <details> and <summary>: Expandable/collapsible sections (no JavaScript needed!):htmlCopyDownloadRun<details> <summary>Click to reveal</summary> <p>Hidden content appears here!</p> </details>
