You're starting a web project and want to avoid chaos in your files?

No worries! In this article, discover the essential steps to properly structure your HTML/CSS project. By following these best practices from the start, you’ll be able to work efficiently and make future modifications with ease.

Why is a good structure essential?

A poorly organized project can quickly become a nightmare, especially if you're working in a team or come back to it after several months. A clear structure allows you to:

  • Save time when adding or modifying features.
  • Facilitate collaboration with other developers.
  • Ensure the maintainability of your code.

Step 1: Organize your files and folders

A good organization starts with a coherent file structure. Here’s an example of a recommended structure:

BASH
/my-project

├── /css
   └── style.css
├── /images
   └── logo.png
├── /js
   └── script.js
├── index.html
└── README.md

Details:

  • /css: Contains all your CSS files.
  • /images: Groups your images to avoid scattering them around.
  • /js: If you're using JavaScript, place your files here.
  • index.html: Your main page.
  • README.md: Provides project information (useful if you’re working in a team or for your own reference).

Step 2: Use naming conventions

Adopt a consistent naming method for your files, classes, and IDs. This will make your code more readable and professional.

Files:

  • Short and explicit names: style.css instead of mystyle.css.
  • No spaces: Prefer dashes `` or underscores _.

Classes and IDs:

  • Use descriptive names in English (the universal coding language):
HTML
<div class="header"></div>
<div id="main-content"></div>

Step 3: Comment and indent your code

Comments:

Add comments to explain important sections of your code.

HTML
<!-- Section for the header -->
<header>
  <h1>Welcome</h1>
</header>

In CSS:

CSS
/* Style for the navigation */
.nav {
  background-color: #f4f4f4;
}

Indentation:

Organize your code with clear indentation to distinguish hierarchical levels.

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

Step 4: Use an external CSS file

Avoid inline or internal CSS to keep your HTML clean. Link an external CSS file in the <head> tag:

HTML
<link rel="stylesheet" href="css/style.css">

Step 5: Modularize your CSS

If your project grows, divide your styles into multiple CSS files:

  • reset.css: Reset default styles.
  • header.css: Styles for the header.
  • footer.css: Styles for the footer.

Then, import them into a main file:

CSS
@import 'reset.css';
@import 'header.css';
@import 'footer.css';

Step 6: Optimize your images and files

Large files slow down your website. Make it a habit to:

  • Compress images using tools like TinyPNG.
  • Minify your CSS files for production (using tools like CSSNano).

Step 7: Regularly test your project

  • On different browsers: Chrome, Firefox, Edge, Safari.
  • On multiple screen resolutions to check responsiveness.

A tool like Google Chrome DevTools can help simulate different screens.

Practical Example: A Structured Base Project

Here’s a simple example structure to get started:

HTML (index.html)

HTML
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>My Structured Project</title>
  <link rel="stylesheet" href="css/style.css">
</head>
<body>
  <header>
    <h1>Welcome</h1>
  </header>
  <main>
    <p>This is my main content.</p>
  </main>
  <footer>
    <p>Footer content</p>
  </footer>
</body>
</html>

CSS (css/style.css)

CSS
/* General styles */
body {
  font-family: Arial, sans-serif;
  margin: 0;
  padding: 0;
}

header {
  background-color: #333;
  color: #fff;
  text-align: center;
  padding: 1rem;
}

footer {
  background-color: #f4f4f4;
  text-align: center;
  padding: 1rem;
}

Conclusion

By following these best practices, you lay a solid foundation for your web projects, making development and maintenance easier. A clear structure is not just about cleanliness; it’s a valuable time-saver in the long run.
