Comments in CSS

Comments in CSS

Comments in CSS are a very useful tool that can help developers better organize and understand code. Comments can be used to explain the purpose of code, remind yourself or other developers of something, or temporarily disable certain styles. In this article, we’ll take a detailed look at comments in CSS and provide code examples.

Single-line Comments

Single-line comments are the most common form of comment, used to add comments to a line of code. In CSS, single-line comments begin with /* and end with */.

Sample code:

/* This is a single-line comment */
body {
font-family: Arial, sans-serif;
}

Multi-line Comments

Multi-line comments can span multiple lines and are used to comment on a section of code or multiple style rules. Multi-line comments begin with /* and end with */.

Sample Code:

/*
This is a multi-line comment.
Can span multiple lines.
*/ 
h1 {
color: blue;
} 

Comment Functions

Comments have many functions in CSS, including but not limited to:

– Explaining the purpose of the code

– Reminding yourself or other developers of something to note

– Temporarily disabling certain styles

Below, we’ll use sample code to illustrate these functions.

Explain the code’s purpose

Sample code:

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

Notes

Sample Code:

/* Note: The border color here is light gray */ 
div { 
border: 1px solid lightgray; 
} 

Temporarily Disable Styles

Sample Code:

/* Temporarily disable the following code 
p { 
font-size: 16px; 
} 
*/ 

Notes on Comments

When using comments, please note the following points:
