Jun 19, 2025 pm 11:09 PMThe 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:
- There should only be one
<main></main>
element per page. - It shouldn't include content repeated across pages (like sidebars or footers).
- It works well with ARIA attributes for enhanced accessibility.
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:
- Wrap only the central content inside
<main>
, like articles, forms, or product details. - Avoid placing it inside elements like
<header>
,<footer>
, or<aside>
. - Consider using
aria-labelledby
oraria-label
if you want to name the main section explicitly for screen readers.
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.

You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.

To reduce the size of HTML files, you need to clean up redundant code, compress content, and optimize structure. 1. Delete unused tags, comments and extra blanks to reduce volume; 2. Move inline CSS and JavaScript to external files and merge multiple scripts or style blocks; 3. Simplify label syntax without affecting parsing, such as omitting optional closed tags or using short attributes; 4. After cleaning, enable server-side compression technologies such as Gzip or Brotli to further reduce the transmission volume. These steps can significantly improve page loading performance without sacrificing functionality.
