Write clean, performant, and maintainable CSS with these best practices and strategies.


🧹 Clean Coding Practices

  • 🚫 Minimize specificity conflicts
  • 🧼 Avoid redundancy by reusing classes and rules
  • 📝 Use shorthand properties when possible:
/* Instead of */
margin-top: 10px;
margin-right: 10px;
margin-bottom: 10px;
margin-left: 10px;

/* Use */
margin: 10px;

⚡ Performance Optimization

  • 📦 Minify CSS to reduce file size
  • 💾 Use browser caching for stylesheets
  • 🎛️ Utilize CSS variables for reusable values:
:root {
  --primary-color: #007bff;
}

.button {
  background-color: var(--primary-color);
}

🧾 Naming Conventions

Follow structured naming like BEM (Block Element Modifier) for better readability:

.card {}
.card__title {}
.card--highlighted {}

✅ Improves collaboration and scalability in large projects
