CSS Comments

Comments in CSS help explain code and guide collaborators. They’re invisible to the browser, allowing you to leave notes, clarify complex rules, or temporarily disable certain styles without deleting them. Well-placed comments make stylesheets easier to understand and maintain over time.

Key Topics

Syntax of Comments

CSS comments begin with /* and end with */. The browser ignores everything inside this comment block.

/* This is a comment explaining why we chose red for the heading */
h1 {
    color: red; /* Inline comment for clarity */
    font-size: 24px;
}

Explanation: Comments can be placed above rules to describe their purpose or inline to explain a single property. They help keep your code understandable for future reference.

When to Use Comments

  • Clarify Complex Rules: Explain non-obvious styling choices.
  • Section Breaks: Use comments to divide your stylesheet into logical sections.
  • Debugging: Temporarily comment out code without removing it permanently.

Best Practices

Keep comments concise and relevant. Over-commenting can be as confusing as having no comments at all. Aim for clarity that helps other developers (and your future self) understand the reasoning behind certain styles.

Key Takeaways

  • Use /* ... */ to add explanations that don’t affect rendering.
  • Comments aid in debugging and maintainability.
  • Keep comments meaningful and to the point.
