Introduction
HTML provides a set of structural elements designed to define different sections and areas of a web page, facilitating better organization and visual layout. These elements play a crucial role in establishing the fundamental structure of a web page and are essential for both semantic meaning and accessibility. This article will delve into the core layout elements provided by HTML, explaining their purpose and usage.
Layout Elements
Div
The <div> element acts as a generic container for grouping and styling content. It offers no inherent semantic meaning, allowing you to create logical divisions within your document based on your specific requirements. You can apply CSS rules to a div to customize its appearance and layout.
<div class="container">
<h2>Welcome</h2>
<p>This is a simple example of using a div for grouping content.</p>
</div>Main
The <main> element represents the main content of a web page. It is used to encapsulate the core content that is most relevant to the document's purpose. The <main> element should ideally contain only one instance within a document.
<main>
<h1>My Blog Post</h1>
<article>
<p>This is the primary content of my blog post.</p>
</article>
</main>Header
The <header> element signifies the introductory content of a page or section. This often includes elements like the site title, navigation links, or a search bar. While multiple headers can exist within a page, they are typically found at the beginning of the page.
<header>
<h1>My Website</h1>
<nav>
<a href="#">Home</a>
<a href="#">About</a>
<a href="#">Contact</a>
</nav>
</header>Nav
The <nav> element is used to define a section of navigation links within a web page. This element is typically associated with the header or footer but can also be used for other navigation sections within the document. The <nav> element is crucial for website structure and user navigation.
<nav>
<ul>
<li><a href="#">Products</a></li>
<li><a href="#">Services</a></li>
<li><a href="#">Blog</a></li>
</ul>
</nav>Aside
The <aside> element designates content that is tangentially related to the primary content of a page. This might include sidebars, related content, or advertisements. The <aside> element is commonly used for content that complements the main content without being integral to the primary flow of the document.
<article>
<h2>My Article Title</h2>
<p>This is the main content of my article.</p>
</article>
<aside>
<h3>Related Articles</h3>
<ul>
<li><a href="#">Article 1</a></li>
<li><a href="#">Article 2</a></li>
</ul>
</aside>Article
The <article> element represents a self-contained piece of content, such as a blog post, news article, or forum comment. It should convey a specific topic or theme and can be independently syndicated or distributed. The <article> element is essential for separating different content units within a web page.
<article>
<h2>My Blog Post</h2>
<p>This is the primary content of my blog post.</p>
</article>Section
The <section> element represents a thematic grouping of content, often used to structure longer documents or web pages. While a section can contain an article, it is distinct from an article itself, grouping related content without necessarily being self-contained. The <section> element provides a clear and logical division for different content areas within a page.
<section id="about-us">
<h2>About Us</h2>
<p>This section introduces our company and its mission.</p>
</section>Footer
The <footer> element signifies the concluding content of a page or section. This commonly includes elements like copyright information, contact details, or site navigation links. It should be placed at the end of the document and is typically used for supplementary information and links. The <footer> element helps provide a consistent structure and concluding information for web pages.
<footer>
<p>© 2023 My Website</p>
