CSS comments are a useful feature that allows you to add notes and explanations within your CSS code without affecting its functionality.

Comments are ignored by the browser and serve as documentation for yourself or other developers working on the codebase. They can help you understand the purpose of certain styles or provide context for future modifications.

The Syntax for CSS Comments

To add a comment in CSS, you can use the following syntax:

/* This is a CSS comment */

Example Usage:

/* Styles for the navigation menu */
.navbar {
  background-color: #333;
  color: #fff;
  /* Adding padding for better spacing */
  padding: 10px;

/* Styles for the main content area */
.content {
  font-size: 16px;
  /* Margin to create separation */
  margin-top: 20px;


In the given example, comments are used to provide additional information and explanations for different sections of the CSS code.

  • The first comment /* Styles for the navigation menu */ helps identify the purpose of the styles that follow and provides a clear context for the .navbar selector.
  • Within the .navbar rule, a comment /* Adding padding for better spacing */ explains the intention behind adding padding to the element.
  • Similarly, in the .content rule, a comment /* Margin to create separation */ clarifies the purpose of the margin-top property.

By using comments effectively, you can improve code readability, enhance collaboration, and make future maintenance or modifications easier.


CSS comments are an essential tool for documenting and annotating your code. They allow you to add explanatory notes that can be helpful to yourself and other developers. Properly placed comments can make your CSS code more understandable and maintainable in the long run.
