We’ll also delve into popular layout techniques like Flexbox and CSS Grid to create responsive and visually appealing web layouts.

Understanding HTML Layout Elements

HTML provides a range of semantic elements for structuring web content, each serving a specific purpose:

• <div>: Generic container for grouping elements.
• <header>: Represents introductory content or a group of navigation links.
• <nav>: Contains navigation links.
• <main>: Encloses the main content of the webpage.
• <section>: Defines a section of content within a document.
• <article>: Represents a standalone piece of content, such as a blog post or news article.
• <aside>: Contains content related to the main content, such as sidebars or callout boxes.
• <footer>: Contains footer information or links.

<header>
    <h1>Website Header</h1>
    <nav>
        <ul>
            <li><a href="#">Home</a></li>
            <li><a href="#">About</a></li>
            <li><a href="#">Contact</a></li>
        </ul>
    </nav>
</header>
<main>
    <section>
