Want to make your CSS code more readable and maintainable?
Learn how to use CSS comments to annotate your stylesheets, making it easier to understand and manage your code. This tutorial provides syntax examples and best practices for writing effective comments.
CSS comments are a simple yet powerful way to organize your code and make it easier to understand for yourself and others. Comments are not rendered by browsers—they're ignored during the page load—but they help you document what your styles are doing.
CSS comments are notes or explanations inside a CSS file. They don't affect how the webpage looks or functions. They are used to explain the purpose of specific blocks of code or to temporarily disable code during debugging.
CSS comments are written using the following syntax:
html syntax ✍
/* This is a CSS comment */
You can use this syntax for both single-line and multi-line comments.
html syntax ✍
/* This styles the main heading */
h1 {
color: blue;
}
The comment describes what the rule set is doing — making the `h1` heading text blue.
html syntax ✍
/* This section styles the
main navigation menu */
nav {
background-color: #f2f2f2;
padding: 10px;
}
Multi-line comments are useful when you want to add detailed notes.
html syntax ✍
/*
button {
background-color: red;
}
*/
This is useful when you want to temporarily remove code without deleting it.
Using CSS comments helps you write cleaner, more maintainable stylesheets. They're especially helpful in team environments or large projects. Make it a habit to comment your code smartly—it pays off in the long run.
