CSS Comment

CSS comments are used to add notes or explanations within your CSS code. These comments are not displayed on the web page but can help you or others understand the code better. They also help in organizing and documenting your styles.

Here's how you use comments in CSS:

Basic Syntax

CSS comments are written between /* and */.

/* This is a single-line comment */

Multi-Line Comments

You can also use comments to span multiple lines:

/*
  This is a multi-line comment.
  It can be used to explain
  more complex sections of code.
*/

Examples

1. Single-Line Comment

   /* Setting the background color for the header */
   header {
     background-color: #f4f4f4;
   }
   

2. Multi-Line Comment

   /*
     This section of CSS is used for styling the main content area.
     It includes settings for margins, padding, and font sizes.
   */
   .main-content {
     margin: 20px;
     padding: 15px;
     font-size: 16px;
   }
   

3. Commenting Out Code

   You can also use comments to temporarily disable parts of your CSS:

   /* 
   .old-button {
     background-color: red;
     color: white;
   }
   */
   
   .new-button {
     background-color: blue;
     color: white;
   }
   

4. Section Headers

   Comments can also be used to organize your CSS file into sections:

   /* Header Styles */
   header {
     background-color: #333;
     color: #fff;
   }
   
   /* Navigation Styles */
   nav {
     font-size: 18px;
   }
   
   /* Footer Styles */
   footer {
     background-color: #f1f1f1;
     padding: 10px;
   }
   

Using comments effectively helps maintain and manage CSS, especially in larger projects.
