How do I use the element to represent the main content of a document?

html <main> tag

The reason for using the <main> tag is to improve the semantic structure and accessibility of web pages, make it easier for screen readers and search engines to understand page content, and allow users to quickly jump to core content. Here are the key points: 1. Each page should contain only one <main> element; 2. It should not include content that is repeated across pages (such as sidebars or footers); 3. It can be used in conjunction with ARIA attributes to enhance accessibility. <main> is usually located after and before <footer> and is used to wrap unique page content, such as articles, forms, or product details, and should be avoided in <header>, <footer> or <aside>; to improve accessibility, aria-labeledby or aria-label can be used to explicitly identify the <main> part.

The <main></main> element is used to wrap the primary content of a webpage — the part that's unique to that page and not shared with others (like headers, footers, or navigation). It helps both developers and assistive technologies identify the core content quickly.

Why Use <main></main> ?

Using <main></main> makes your HTML more semantic. That means screen readers and search engines can better understand your page structure. It also improves accessibility by allowing users to jump straight to the main content.

Some key points:

Where to Place <main></main> in Your HTML

The <main></main> tag usually comes after the header and navigation but before the footer. Here's a typical layout:

 <header>...</header>
<nav>...</nav>
<main>
  <!-- Unique page content -->
</main>
<footer>...</footer>

This structure helps users and tools find the main content easily without having to scan through repeated parts of the site.

How to Use <main> Effectively

Here are some practical tips:

A simple example:

 <main aria-labelledby="page-title">
  <h1 id="page-title">Welcome to Our Blog</h1>
  <article>...</article>
</main>

This helps screen readers announce the main content clearly.


That's basically how to use <main></main> — straightforward, but important for structure and accessibility.
