HTML templating is a powerful technique to separate presentation logic from application code, enabling reusable, maintainable, and dynamic web content. Below are key concepts and best practices for advanced templating in web development.

🧩 Template Engine Overview

Common engines include:

  • Handlebars (via /en/tutorials/html-templating-basics)
  • Pug (Jade)
  • Mustache

Each engine uses its own syntax for embedding logic into HTML. For example:

// Pug example
div#header
  h1= title
  p= content

📌 Key Use Cases

  1. Dynamic Content Generation
    Inject data into HTML using variables and loops.

✅ Best Practices

  • Keep templates clean and minimal
  • Use semantic HTML tags for structure
  • Avoid overnesting for readability
  • Implement template caching for performance
