HTML Layout

HTML layout involves structuring and organizing the content on a webpage. It's crucial for creating a coherent and user-friendly design. Here's an overview of HTML layout with examples:

Basic HTML Structure

Before diving into layout techniques, let's start with a basic HTML template:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
        /* Add CSS styles here */
    </style>
</head>
<body>
    <!-- Page content goes here -->
</body>
</html>

Layout Techniques

1. Block-Level Elements

Block-level elements take up the full width available and start on a new line. Common block-level elements include <div>, <header>, <footer>, <article>, and <section>.

Example:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Block-Level Example</title>
    <style>
        header, footer, section {
            border: 1px solid black;
            padding: 10px;
            margin: 10px 0;
        }
    </style>
</head>
<body>
    <header>
        <h1>Header</h1>
    </header>
    <section>
        <h2>Section</h2>
        <p>This is a section of content.</p>
    </section>
    <footer>
        <p>Footer</p>
    </footer>
</body>
</html>

2. Inline Elements

Inline elements take up only as much width as necessary and do not start on a new line. Examples include <span>, <a>, and <img>.

Example:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Inline Example</title>
    <style>
        .highlight {
            background-color: yellow;
        }
    </style>
</head>
<body>
    <p>This is a <span class="highlight">highlighted</span> word in a paragraph.</p>
</body>
</html>

3. Flexbox

Flexbox is a CSS layout module that allows you to create complex layouts easily by aligning items in rows or columns.

Example:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Flexbox Example</title>
    <style>
        .container {
            display: flex;
            justify-content: space-between;
        }
        .box {
            width: 30%;
            padding: 20px;
            border: 1px solid black;
        }
    </style>
</head>
<body>
    <div class="container">
        <div class="box">Box 1</div>
        <div class="box">Box 2</div>
        <div class="box">Box 3</div>
    </div>
</body>
</html>

4. Grid Layout

CSS Grid Layout is a powerful tool for creating complex grid-based layouts.

Example:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Grid Layout Example</title>
    <style>
        .grid-container {
            display: grid;
            grid-template-columns: repeat(3, 1fr);
            gap: 10px;
        }
        .grid-item {
            padding: 20px;
            border: 1px solid black;
        }
    </style>
</head>
<body>
    <div class="grid-container">
        <div class="grid-item">Item 1</div>
        <div class="grid-item">Item 2</div>
        <div class="grid-item">Item 3</div>
        <div class="grid-item">Item 4</div>
        <div class="grid-item">Item 5</div>
        <div class="grid-item">Item 6</div>
    </div>
</body>
</html>
