CSS Comments

CSS Comments

Comments are used to explain the CSS code, and may help when you edit the source code at a later date.

Comments are also used to temporarily disable sections of CSS code within a stylesheet.

Comments are ignored by browsers!

A CSS comment is placed inside the HTML <style> element, and starts with /* and ends with */:

Example

/* This is a single-line comment */
p {
  color: red;
}

You can add comments wherever you want in the code:

Example

p {
  color: red;  /* Set text color to red */
}

Even in the middle of a code line:

Example

p {
  color: /*red*/blue; 
}
Try it Yourself »

Comments can also span multiple lines: 

Example

/* This is
a multi-line
comment */

p {
  color: red;
}

HTML and CSS Comments

From the HTML tutorial, you learned that you can add comments to your HTML source by using the <!--...--> syntax.

In the following example, we use a combination of HTML and CSS comments:

Example

<!DOCTYPE html>
<html>
<head>
<style>
p {
  color: red; /* Set text color to red */
}
</style>
</head>
<body>

<h2>My Heading</h2>

<!-- These paragraphs will be red -->
<p>Hello World!</p>
<p>This paragraph is styled with CSS.</p>
<p>HTML and CSS comments are not shown in the output.</p>

</body>
</html>
