HTML5 introduced new semantic tags to improve webpage structure and accessibility. 1. <header> defines introductory content or navigation. 2. <nav> contains major navigation links. 3. <main> holds the unique, primary content of a page. 4. <article> represents self-contained content like blog posts. 5.
HTML5 introduced a bunch of new tags that make web development more semantic and organized. These tags help browsers, search engines, and developers better understand the structure of a webpage without relying too much on generic divs and classes.
Here are some of the most commonly used HTML5 tags you’ll see in modern websites:
1. <header></header>
This tag is typically used at the top of a page or within a section to introduce content — like site navigation, logos, or introductory text. It doesn’t have to be the very top of the whole page; it can also be used inside a <section></section> or <article></article>.
For example:
<header>
<h1>My Website</h1>
<nav>
<ul>
<li><a href="#home">Home</a></li>
<li><a href="#about">About</a></li>
</ul>
</nav>
</header>2. <nav>
The <nav> element defines a section of navigation links. It’s useful for menus, tables of contents, or any major block of links. Screen readers and search engines use this to skip or index navigation areas.
You’ll usually find it inside <header>, but not always.
3. <main>
This tag represents the main content of the document — the unique part that isn’t repeated across pages (unlike headers or footers). There should only be one <main> per page, and it shouldn't be nested inside other elements like <header>, <footer>, or <aside>.
4. <article>
Use <article> when you want to define a self-contained piece of content that could stand alone — like blog posts, forum entries, or news articles.
Example:
<article> <h2>Blog Post Title</h2> <p>This is the content of the article...</p> </article>
5. <section></section>
A <section></section> groups related content together. Think of it like a thematic break in the page. You might use it to divide different parts of your homepage: features, testimonials, contact info, etc.
