HTML Layout Elements and Techniques
Creating a well-structured layout is a fundamental part of web design. HTML provides several elements and techniques to help you organize and structure your content effectively.

The <header> element represents introductory content or a set of navigational links.
Example:
<header>
<h1>Website Header</h1>
</header>1.2. The <nav> Element
The <nav> element defines a set of navigation links.
Example:
<nav>
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Services</a></li>
<li><a href="#">Contact</a></li>
</ul>
</nav>1.3. The <main> Element
The <main> element represents the main content of the document.
Example:
<main>
<h2>Main Content</h2>
<p>This is the main area of the website.</p>

There are several techniques to create layouts in HTML, including using CSS for advanced styling and positioning.
2.1. CSS Flexbox
CSS Flexbox is a layout model that allows you to create complex layouts with simple and flexible syntax.
Example:
<div style="display: flex;">
<div style="flex: 1;">Flex Item 1</div>
<div style="flex: 1;">Flex Item 2</div>
<div style="flex: 1;">Flex Item 3</div>

CSS Grid Layout is a two-dimensional layout system for the web that allows you to create complex and responsive grid-based designs.
Example:
<div style="display: grid; grid-template-columns: repeat(3, 1fr); gap: 10px;">
<div>Grid Item 1</div>
<div>Grid Item 2</div>
<div>Grid Item 3</div>
</div>2.3. Using <div> Elements for Layout
The <div> element is often used as a container for other elements to apply styles and layout using CSS.
Example:
<div class="container">
<header class="header">Header</header>
<nav class="nav">Navigation</nav>
<div class="main">Main Content</div>
<aside class="sidebar">Sidebar</aside>
