CSS Comments
CSS comments are used to explain code and make stylesheets easier to understand. Comments are ignored by the browser and do not affect how styles are applied. They are very helpful for documentation and teamwork.
Why Use CSS Comments?
- To explain complex CSS rules
- To organize large stylesheets
- To make code easier to maintain
- To temporarily disable CSS code
CSS Comment Syntax
CSS uses a specific syntax for comments.
A comment starts with /* and ends with */.
/* This is a CSS comment */
Single-Line Comments
Although CSS does not officially support single-line comments, you can still write short comments on one line using the same syntax.
/* Header styles */
header {
background-color: #333;
}
Multi-Line Comments
Multi-line comments are commonly used to describe sections or explain groups of CSS rules.
/*
Navigation Bar Styles
These styles control the main menu
*/
nav {
display: flex;
justify-content: space-between;
}
Using Comments to Organize CSS
Comments are often used to separate different parts of a stylesheet for better readability.
/* =========================
Layout Section
========================= */
.container {
max-width: 1200px;
margin: auto;
}
Commenting Out CSS Code
You can temporarily disable CSS rules by commenting them out. This is useful for debugging and testing.
/*
.button {
background-color: blue;
color: white;
}
*/
Best Practices for CSS Comments

- Use comments to explain why code exists, not just what it does
- Avoid overusing comments
- Update comments when code changes
Common Mistakes with CSS Comments
