The <h1> HTML element is used to define the most important heading on a webpage or within a section of content. It represents the highest level of heading and is typically used for the main title or heading of a document or a significant section within it. The <h1> element is a block-level element that provides semantic meaning, indicating the primary topic or purpose of the content that follows.
Usage and Characteristics
The <h1> element is crucial for both accessibility and search engine optimization (SEO), as it helps search engines and assistive technologies understand the structure and hierarchy of the content. While a webpage can technically contain multiple <h1> elements, especially in HTML5 where they can be used within different sections or articles, it is generally recommended to use a single <h1> per page to represent the main title or heading. Here is an example of how the <h1> tag can be used:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document Title</title>
</head>
<body>
<header>
<h1>Welcome to My Website</h1>
</header>
<main>
<section>
<h1>About Us</h1>
<p>This section provides information about our company.</p>
</section>
</main>
</body>
</html>Valid Attributes for <h1>
The <h1> element does not have specific attributes beyond the global attributes, which include:
| Attribute | Description |
|---|---|
| class | Specifies one or more class names for the element, used for CSS styling. |
| id | Defines a unique identifier for the element, useful for linking and JavaScript. |
| style | Contains inline CSS styles for the element. |
| title | Provides additional information about the element, often displayed as a tooltip. |
