HTML Style Guide

An HTML style guide provides conventions and best practices for writing clean, consistent, and maintainable code. By following a style guide, you ensure that your markup is more readable, easier to maintain, and consistent across large projects or multiple team members.

Key Topics

Naming Conventions

Example: Use meaningful class names that reflect the purpose or content of the element.

<div class="product-list">
    <div class="product-item">Item 1</div>
</div>

Indentation and Spacing

Example: Use consistent indentation (often 2 or 4 spaces) to improve readability.

<nav>
    <ul>
        <li><a href="#">Home</a></li>
        <li><a href="#">Services</a></li>
    </ul>
</nav>

Semantics and Consistency

Example: Always use semantic elements appropriately and consistently, like using <header> for the top section of the page.

<header>
    <h1>Page Title</h1>
</header>

Style Guide Example

This example showcases a snippet following a basic style guide. A full code sample is provided below.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8" >
    <meta name="viewport" content="width=device-width, initial-scale=1.0" >
    <title>Styled Project</title>
    <link rel="stylesheet" href="css/main.css">
</head>
<body>
    <header>
        <h1>Site Title</h1>
    </header>
    <main>
        <section class="intro">
            <h2>Introduction</h2>
            <p>Short description of the site.</p>
        </section>
    </main>
    <footer>
        <p>© 2023 Company</p>
    </footer>
</body>
</html>

Explanation: Consistent indentation, meaningful class names, and proper use of semantic elements reflect a good HTML style guide, making the code easier to understand and maintain.
